Features

The PCR-LE Series is equipped with the following features.
• Various power supply simulations Power line abnormalities such as outages and voltage dips can
be simulated. This is a basic feature for power-supply-environ­ment testing.
• Various measurements The rms voltage and current, the peak voltage and current, the
active power, apparent power, and power factor of the output can be measured. Harmonic analysis (up to the 40th harmonic) can be performed on the output current.
• DC output The PCR-LE Series can generate DC output and AC + DC out-
put. This makes it possible to use the PCR-LE Series in a wide variety of fields, including chemistry and physics.
• Sequences The output voltage, frequency, and waveform can be changed
over time. Power-supply-environment testing can be automated. In addition to the AC output sequences, DC output and AC + DC
output sequences are also available. A variety of standard tests can also be performed.
• Sensing and regulation adjustment Even if the load device is at a remote location, the PCR-LE Series
can stabilize the voltage across the load by correcting for volt­age drops.
There are two types of sensing: hard sensing and soft sensing. The different types of sensing are used depending on the load conditions and how you will use the PCR-LE Series.
• Output current control The output limit function can be used to limit the output current
(rms) to a fixed value to perform continuous operation. Continuity tests on electrical equipment (such as switchboards, breakers, and wiring devices) can be performed under stable conditions.
• Power management function (power saving function) A sleep function, which turns the power units off to reduce power
consumption when output is not generated for the specified length of time, and a power-saving function, which operates the power units at the bare minimum settings as required by the sup­ply load, are available.
• Memory function Up to 99 entries of output frequency, voltage (AC or DC), and
waveform bank settings can be saved to the internal memory. The contents of internal memory, panel settings, power line ab-
normality simulations, sequence data, and waveform bank data can be saved to a USB memory device.
• External communications The PCR-LE Series can be controlled remotely through its
RS232C interface. If an optional interface board is used, the PCR-LE Series can be controlled remotely through USB, GPIB, and LAN interfaces.
• Single-phase, three-wire output/ Theree-phase output (Optional) Use of the optional 2P05-PCR-LE allows the outputs of two PCR-
LEs to be connected in series for use as single-phase, three-wire system power supplies. Use of the optional 3P05-PCR-LE allows the outputs of three PCR-LEs to be connected in star connection for use as three-phase system power supplies
• Master-Slave parallel control (Optional) The PD05M-PCR-LE/PD05S-PCR-LE option enables the PCR-LE
Series to be operated in parallel (except for the PCR500LE and PCR1000LE; up to five units or within 27 kVA of power; different models can be mixed).
• External analog signal control (optional) The EX05-PCR-LE/EX06-PCR-LE option enables you to control
the PCR-LE2 Series output using external analog signals. .

User’s Manual -Advanced-
• Using the synchronization Function The synchronization function synchronizes the frequency and
phase of the PCR-LE output voltage with a 50 Hz or 60 Hz input power supply.
• Using the Voltage Compensation Function The compensation function compensates for voltage drops in the
load cables when the load is connected to the PCR-LE over a long distance.
• Using Power Line Abnormality Simulations In AC mode, you can simulate power supply line errors by stop-
ping the PCR-LE output and decreasing and increasing the volt­age (to simulate voltage dips and pops).
• Using the Sequence Function A sequence is a series of settings - values such as the output
voltage, frequency, and time - that are saved in advance and are then recalled and automatically carried out in order at a later time.
• Using the Harmonic Current Analysis Function You can perform harmonic analysis of the output current.
• Generating Special Waveforms (Waveform bank) You can generate peak-clipped sine waveforms.
• Setting the Output Impedance The PCR-LE output impedance (output resistance) is approxi-
mately 0 Ω. Commercial power supplies have an impedance (resistance) of several milliohms to several ohms. You can set the PCR-LE output impedance. This enables you to simulate the same environment as that which is provided by commercial power supplies.
• Setting Soft Starts (The voltage rise time) To prevent the output from being turned off (the alarm from be-
ing activated) and the voltage from dropping due to the load device’s inrush current that exceeds the rated capacity of the PCR-LE, you can control the inrush current by having the output voltage rise gradually when the output is turned on.
• Fixing the Internal Vcc To minimize loss in the linear amplifier section, the PCR-LE au-
tomatically adjusts the linear amplifier supply voltage (Vcc) to a level that is suitable for the output voltage. You can fix the Vcc voltage of the PCR-LE. This is useful when you want to prioritize the output voltage response over the product’s efficiency.
• Selecting the Response The PCR-LE uses a high-speed amplifier. Depending on the load
circuits (especially in the case of capacitive loads) and the wiring conditions, the output may become unstable may oscillate. You can set the response speed of the internal amplifier according to the load conditions and how you will use the PCR-LE.
• Using the Power Management Functions The PCR-LE has the following two power management functions:
a sleep function and a power-saving function
• External analog signal control (optional) You can use the optional analog signal interface board to control
the product with external analog signals.

OUTPUT terminal block.
Securely connect the load cables to the OUTPUT ter-
4
minal block.
If the load has a ground (GND) terminal, be sure to connect it to the G terminal of the PCR-LE Series OUTPUT terminal block. Be sure to use a wire that is greater than or equal to the diameter of the wires used to connect the load.

The values vary depending on conditions such as the wire covering (insulator), the wire material (allowable temperature), and whether there are multiple cores in the cable. For cables other than those specified in this table, consult with a qualified engineer.
WARNING
Risk of electric shock. Before you connect cables to the OUTPUT terminal block, be sure to turn the POWER switch off, and then remove the power plug from the outlet or turn off the switchboard.
- Note -
The L and N terminals of the OUTPUT terminal block are isolated from the input power supply. The polarity does not constitute a problem in terms of safety. The polarity matters in synchro mode (in which the product is synchronized with the input power supply) and DC mode, so check the polarity of the load before you connect it to the product. You can use either L or N to ground the product.
In DC mode and AC+DC mode, N is the reference. When N has a positive polarity, L is positive electric potential. When N has a negative polarity, L is negative electric potential.

Twist the load wires (L and N), and connect between the output ter­minal and load with the shortest wires possible. If you cannot twist the wires, we recommend that you run the wires alongside each other and tie them together at several points with cable ties.
When you are not using the OUTPUT terminal block, attach the ter­minal cover.
Use the upper holes to fix the terminal

If you do not insert the terminal block tray all the way into its storage compartment, an electric current will not flow through the PCR-LE Series even if the POWER switch is turned on.
If the load is located at a remote location, the PCR-LE may need be controlled remotely.
Remote control can be used to turn the output off, but it cannot be used to turn the POWER switch off. If you want to connect the PCR­LE Series to a load that is located at a remote location, install a switch between the OUTPUT terminal block and the load to prevent electric shock. Then, turn that switch off.
WARNING
Risk of electric shock.
• Before you install the switch between the OUTPUT ter­minal block and the load, be sure to turn the POWER switch off and remove the power plug from its outlet or turn off the breaker of the switchboard.
• The current rating of the switch must be greater than or equal to the maximum current of the PCR-LE Se­ries.
• For the switch circuit, use a two-pole type switch that can cut off the L and N wires simultaneously.
• Be sure to turn the switch off before connecting the load to the terminal at the load end of the switch.
• Do not touch the switch terminals when the POWER switch is on. Do not touch the switch terminals when the POWER switch is on. Before you connect cables to the OUTPUT terminal block, be sure to turn the POWER switch off, and then turn off the switchboard.

Connecting the Load (Cont.)
Connecting to the front-panel outlets
The PCR-LE Series can generate power from the OUTPUT termi­nal block on the rear panel and the outlets on the front panel. The specifications of the front-panel outlets are not regulated. Their per­formance may decrease.
CAUTION
The maximum rated voltage of the front-panel outlets is 250 Vac.
Max. output voltage: 250 Vac(rms)
Maximum output current:
10 Aac (rms) per outlet (on models other than the PCR500LE) 5 Aac (rms) total for the two outlets on the PCR500LE 10 Aac (rms) total for the two outlets on the PCR1000LE
Do not disconnect the load when the maximum rated voltage of the outlets has been exceeded or in DC mode. Doing so may cause the product to malfunction.
On the PCR-LE Series (excluding the PCR500LE and PCR1000LE), if an overcurrent is detected, the breaker trips, and the output is cut off.
The outlets are designed for power plugs like those shown below.
NEMA5-15
NEMA1-15
The output current may be lower than the maximum output current due to the output voltage, the output frequency, and the load power factor.
For example, on the PCR1000LE, if the output voltage is 115 V, the load power factor is 0.7, and the output frequency is 50 Hz, the to­tal maximum output current for the two outlets is 7.61 A. If an output current of 5 A is drawn from one of the outlets, the maximum output current that can be drawn from the other outlet is 2.61 A.
Turn the POWER switch off.

Setting the output voltage
You can set the output voltage while output is on or off. The measured value is always displayed.
Set the voltage limit to prevent the PCR-LE Series from generat­ing a voltage that is greater than is necessary.
The PCR-LE Series output impedance is extremely low, so de­pending on the load, a current may flow even if the voltage is set to 0.0 V. Be sure to turn the output off or turn the POWER switch off when you do not want any current to flow and before you connect a load.
•
AC mode
Specify the AC voltage that you want to generate. You can specify an output voltage as low as 0.0 V, but the
voltage that is actually generated will not be lower than a value in the range of 0.1 V to 0.6 V (the value varies depend­ing on factors such as the output voltage range and the tem­perature).
•
DC mode
Specify the DC voltage that you want to generate.
•
AC+DC mode
Specify the AC and DC voltages that you want to generate. The AC voltage setting is shared between AC and AC+DC
modes. The DC voltage setting is shared between DC and AC+DC
modes. The set AC and DC voltages must meet the following condi-
tions: (1) they must be within the setting range of the volt­age limit and (2) the AC+DC waveform’s peak value must be within -431 V to 431 V when the H range is selected and within -215.5 V and 215.5 V when the L range is selected.
When the output is on
If the output is on, the measured value (output terminal voltage) and the setting are displayed. You can adjust the output volt­age while viewing the output voltage setting and the measured value.
If you are using the rotary knob to set the value, you may in­crease or decrease the value too much because the display response is slow. Until you have an intuitive understanding of the display response speed, change the output voltage while viewing the voltage setting or make small changes to the out­put voltage.

The internal circuits and the output of the PCR-LE Series are not separated by a mechanical switch or relay. The PCR-LE Series turns the output off by electrically increasing the output impedance. This enables you to turn the output on and off with­out chattering. When the output is off, the output is set to high impedance, and the output voltage is nearly 0 V.
Even when the output is on, the following impedances are present, so if the load is a battery or a similar device, a slight current may flow into the PCR-LE Series, and the load may be discharged.

You can set the voltage surge suppression that is activated when the output is turned off.
When the output is off, the output of this product is at high im­pedance.
If voltage surge suppression is set to ON (factory default set­ting), immediately after the output is turned off, the output voltage is set to 0 V (low output impedance), and then the impedance is changed to high. To prevent large overshooting and undershooting by the load immediately after the output is turned off, we recommend that you use the PCR-LE Series with the voltage surge suppression set to on.
When voltage surge suppression is on, an unexpected current may flow through the product immediately after the output is turned off depending on the connected load (power condition­er, regenerative inverter, battery, etc.). This may affect the test. Turn voltage surge suppression off for the above loads.

Setting the aperture time (measurement time)
With a longer aperture time, the measurements become more stable, but it takes longer to update the display of the mea­sured values. Guidelines for the aperture time when the signal includes an AC component are given below.
• When the period of the AC is known, you can obtain the most accurate measurement results if you set the aperture time to an integer multiple of the period.
Example: If the period of the AC component is 0.1 s, you can obtain the best results in the shortest time if you set the aper­ture time to 0.1 s.
• When the period of the AC component is unknown, you can obtain comparatively stable measurement results if you set the aperture time to a value that is at least 10 times the ex­pected period.
If the period is set greater than the aperture time, line voltages cannot be measured correctly.
If the harmonic current analysis function is in use and the peri­od is set greater than the aperture time, correct measurements cannot be made.
Press OTHERS (SHIFT+MEMORY), 1/3 (F6), 2/3 (F6), and then APERTUR (F1) to set the aperture time.

The following shows an example of how to calculate the rated current on the PCR1000LE.
• If the output voltage is 80 V, the load power factor is 0.6, and the output frequency is 50 Hz,
the rated current is 10 A × 0.825 = 8.25 A.
• If the output voltage is 250 V, the load power factor is 0.4, and the output frequency is 60 Hz,
the rated output current is 1 000 W/250 V × 0.65 = 2.6 A.
• If the output voltage is 80 V, the load power factor is 0.6, and the output frequency is 10 Hz,
the rated current is 10 A × 0.775 = 7.75 A (≤ 8.25 A).

setting and frequency setting. They prevent damage to the load caused by mistaken operations and limit the current that flows through the load.
•
Protection Functions Protection functions apply limits when there is a danger of
damaging the internal circuitry of the PCR-LE Series or to protect the DUT.
When a protection function is activated, an alarm (ALM-xx) or a trouble indication (TRBL-xx) is generated, and the output is turned off.

Limit You will not be able to specify voltages that are outside
of the set limit range.
Protection If the measured voltage exceeds the OVP value, an
alarm occurs, and the output turns off.
Protection If the measured voltage falls below the UVP value, an
alarm occurs, and the output turns off.
Limit You will not be able to specify frequencies that are
outside of the set limit range.
Limit If the upper limit is exceeded, the output turns off, or
the output voltage is controlled so that the limit value is not exceeded. You cannot set the lower limit. You can set how the PCR-LE Series behaves when the limit is exceeded (whether to turn off the output or control the output voltage). If you select to turn off the output, you can set the time that must elapse before the output is turned off when the current limit is exceeded. If you select to control the output voltage, the following functions will not be available.
• Turn soft start on (set the rise time)
• Execute power line abnormality simulations
• Run sequences
• Use the compensation function’s software sensing and regulation adjustment
Limit This function instantly limits the peak output current.
You can set positive and negative limits.
Protection This function protects the internal semiconductors of
the PCR-LE Series. If a temporary overcurrent—such as an inrush current—occurs, an alarm occurs, and the output turns off.
Protection If the input voltage falls below the rating, a trouble indi-
cation occurs, and the output turns off.
Protection If the output current exceeds the rated current or cur-
rent limit, an alarm occurs, and the output turns off.
Protection If the internal temperature increases abnormally, an
alarm occurs, and the output turns off.

AC+DCLOAD
Limits can be placed on the PCR-LE Series output voltage setting and frequency setting. They prevent damage to the load caused by mistaken operations and limit the current that flows through the load. You can set limits in advance according to the load conditions.
You can set these values while output is on or off.
Voltage upper and lower limits
Limits can be placed on the PCR-LE Series output setting. They prevent damage to the load caused by mistaken operations. You can set limits in advance according to the load conditions.
After you set the voltage limits, you will no longer be able to specify voltage values that are outside of the range that you have set. The only exception is 0 V. You can still use the nu­meric keypad to specify this value.
Set the limits so that the lower limit is less than or equal to the upper limit.
In AC+DC mode, there are AC limits and DC limits. Check the title in the entry area, and then set the value.
During single-phase, three-wire output and three-phase output (optional), set the limits using phase voltages.
To set the voltage upper limit, press V and then VMAX (F4). To set the voltage lower limit, press V and then VMIN (F5).

Current limit and peak current limits
Limits can be placed on the current that flows through the load. There is a current limit, a positive peak current limit, and a neg­ative peak current limit. You can set limits according to the load conditions.
•
Current limit
You can set the output current’s upper limit. You cannot set the lower limit.
The limit operates on the rms value of the output current. You can set how the PCR-LE Series acts (turn the output off/
do not turn the output off) when the current limit is exceeded. The actual current limit is activated at 1.1 times the rated cur-
rent or the current limit, whichever is less. The rated current is automatically derated (reduced) depending on the output conditions (output voltage, frequency, and load power fac­tor).For details of rated output current, see ”About the output and the load”. -> p94
•
Positive peak current limit and negative peak current limit
You can set positive and negative peak current limits. These instantly limit the peak output current. If the peak current approaches the peak current limit (ap-
proximately 94 % of the peak current limit), “IPK.LIM” is dis­played.
Setting the peak current limits does not change the load level meter’s full scale.

turned off when the current limit is exceeded
In AC mode, you can set the amount of time that elapses after the current limit is exceeded (the amount of time during which the current limit is continuously exceeded) before the output is turned off. This is useful when you don’t want the output to be turned off due to issues such as inrush current causing short­term overloads.
If the voltage setting is at or lower than 10 V (L range) or 20 V (H range), the output will turn off after 3 s even if you set the trip time to 4 s or longer.
The amount time until the output is turned off may become large due to the state of the load or the timing of the PCR-LE Series internal current measurement. There is a delay in the re­sponse depending on the aperture time setting.
If the full scale bar of the load level meter continues to be lit, the temperature inside the PCR-LE is high. If an overload oc­curs repeatedly, the time until the output is turned off may be shortened.

Clearing alarms
Press ALM CLR (SHIFT+CLR) to clear the alarm, and then fix the problem that caused the alarm.
If an alarm still occurs even after you have corrected all the causes of alarms, the PCR-LE Series may be malfunctioning. Stop using it immediately, and contact your Kikusui agent or distributor. Inform the individual that you contact of the alarm code that is displayed.
Input voltage drop protection
If the input voltage drops lower than the rating, the input volt­age drop protection function is activated, and an alarm (AC INPUT LOW) is generated. Adjust the input voltage so that it is within the range in the specifications. If the input power supply wiring is long, use wires that have a large diameter to make the voltage drops smaller.
Overheat protection (OHP)
If the internal temperature rises to an abnormal level, the over­heat protection is activated, and an alarm (ALM-02: OHP) is generated. Leave the PCR-LE Series on, and wait for approxi­mately 10 minutes.
If the alarm has stopped occurring after 10 minutes, the PCR­LE Series may have been installed incorrectly, or the dust filter may be clogged.
If there are no problems with the installation or the dust filter, stop using the PCR-LE Series immediately, and contact your Kikusui agent or distributor to request repairs.
Overload protection
If the output current exceeds the rated current or the current limit (-> p32), the overload protection is activated, and an alarm is generated (ALM-06: OVERLOAD).
During reverse power flow, the protection is activated at 30% of the rated current or the current limit, whichever is less.

What to do if the breaker trips
The PCR500LE and PCR1000LE do not have a breaker. On the PCR2000LE, PCR3000LE, PCR4000LE, PCR6000LE,
and PCR9000LE, if an output current of 10 A or greater flows from one of the outlets on the front panel, the breaker next to the outlet may trip, which will cut off the outlet’s output. If the breaker trips, the red button (the breaker button) will pop out.
The total output current that can be generated from the two outlets and the OUTPUT terminal block on the rear panel is the rated output current. If the rated value is exceeded, the over­load protection function is activated.
For example, on the PCR4000LE, when the output voltage is 100 V (the 100 V range), the load power factor is 1, and the output frequency is 50 Hz, if an output current of 10 A is flowing from each outlet, the maximum output current that can be gen­erated from the OUTPUT terminal block is (40 A - 10 A - 10 A =) 20 A.

Using the Synchronization Function

- Advanced -

The synchronization function synchronizes the frequency and phase of the PCR-LE Series output voltage with a 50 Hz or 60 Hz input power supply. This is valid in AC mode and AC+DC mode.
This is useful in situations such as when the display of an exter­nal measuring instrument is not stable.
Setting the synchronization delay phase angle enables you to manage the synchronization phase of the input voltage on the three-phase input model (PCR9000LE) with a high degree of precision.
Turning the synchronization function on disables the frequency limit function.
Turning the synchronization function on and off
If the input voltage frequency is outside of the rated range or if the input power supply voltage distortion and the noise are extremely large, synchronization is not possible. In these situa­tions, “SYNC NG” is displayed.
Press SYNC (SHIFT+9) to turn the synchronization function on and off.

If the frequency when you are using the synchronization func­tion is within the frequency limits, the frequency is set to the 50 Hz or 60 Hz, whichever the PCR-LE Series was synchronized to.
If the frequency when you are using the synchronization func­tion is outside the frequency limits, the frequency limit function will be activated.
If the frequency when you are using the synchronization func­tion is lower than the lower limit, the frequency is set to the lower limit.
If the frequency when you are using the synchronization func­tion is higher than the upper limit, the frequency is set to the upper limit.

Using the Voltage compensation Function

The compensation function compensates for voltage drops in the load cables when the load is connected to the PCR-LE Series over a long distance. The PCR-LE Series has three types of compensation functions: soft sensing, hard sensing, and regulation adjustment. Use the different compensation functions depending on how you need to use the PCR-LE Series.
During single-phase, three-wire output and three-phase output (optional), regulation adjustment is invalid.
WARNING
Risk of electric shock.
• Before you connect the load or the sensing cables, turn the POWER switch off, and then remove the pow­er plug from the outlet or turn off the switchboard.
• Firmly attach the terminal box cover.
•
Hard sensing
Connect the PCR-LE’s internal output voltage compensation point directly across the load. Because compensation is per­formed in real time, the output voltage can be stabilized at a high speed.
Because the impedance (the combination of the resistance and the inductance) of the power line across the load will be included in the compensation circuit, the power circuit’s sta­bility decreases. The PCR-LE Series operations may become unstable (for example, it may oscillate) depending on the wiring and the load type. If the operations become unstable, use soft sensing.
It is recommended that you use soft sensing if you are using a load that does not require a fast output voltage response speed.
You cannot use hard sensing in the following situations.
When the output is on When you are setting the output impedance (ON) When you have selected the normal response speed (ME-
DIUM) or the fast response speed (FAST).
•
Soft sensing
The voltage of the sensing point is measured by the PCR-LE Series measurement functions, and any insufficiencies in the voltage are automatically compensated for. The performance of the PCR-LE Series such as the stability of the voltage, out­put voltage response to sudden changes in the load current, and waveform quality (distortion ratio) is lower than that avail­able during normal operation.
Even in DC mode, the performance is lower than that avail­able during remote sensing of a normal DC power supply.
The maximum voltage that soft sensing can compensate is “the PCR-LE Series’ output voltage ±10 %.” The maximum output voltage during compensation is limited by the rated voltage of the PCR-LE Series.
If the frequency is less than 40 Hz, soft sensing is disabled. You cannot use soft sensing in the following situations.
When the output is on When in AC+DC mode When you are setting the output impedance (ON) When you have configured the PCR-LE Series so that it
does not turn output off when the current limit is exceeded (DISABLE)
When you have specified the waveform bank When power line abnormality simulations are being per-
formed When sequences are being performed When soft start is on.
•
Regulation adjustment
This function calculates the voltage drops that are caused by the output current and increases the output voltage just by the calculated voltage drops.
Use this function when there is a great distance between the PCR-LE Series and the load and you want to stabilize the voltage across the load. This function does not require you to connect the sensing cables that the hard sensing and soft sensing functions require.
The performance of the stabilization accuracy, distortion ratio, and response speed of the voltage is lower than the normal performance of the PCR-LE Series. Depending on how you are using the PCR-LE Series, you may not be able to use this function. Check the operation that you will perform before you use the regulation adjustment function.
The maximum voltage that regulation adjustment can com­pensate is “the PCR-LE Series’ output voltage + 10 %.” The maximum output voltage during compensation is limited by the rated voltage of the PCR-LE Series. If the output current is 10 % or less of the maximum rated current, the voltage is not compensated.
You cannot use regulation adjustment in the following situa­tions.
When the output is on When in AC+DC mode, in DC mode When you are setting the output impedance (ON) When you have configured the PCR-LE Series so that it
does not turn output off when the current limit is exceeded (DISABLE)
When you have specified the waveform bank When power line abnormality simulations are being per-
formed When sequences are being performed When soft start is on.

the chassis.
Twist the load wires (L and N), and connect between the output terminal and load with the shortest wires possible. If you cannot twist the wires, we recommend that you run the wires alongside each other and tie them together at several points with cable ties.
The sensing feature can compensate up to 1.5 V for a single line. Select a load cable that has sufficient current capacity to prevent the voltage drop in the cable from exceeding the com­pensation voltage.
As the PCR-LE Series output voltage becomes small, so too does the detected voltage. If the PCR-LE Series output volt­age is small, reduce the voltage drops in the cables by using cables that have large diameters to wire the load, connecting the load so that the cables are as short as possible, and taking other similar precautions.
CAUTION
Risk of damage to the product and the load. If the sensing cables become disconnected or the polarities are incorrect, an overvoltage will be generated in the output. The protection function will be activated and the output will be turned off, but an overvoltage will be generated for the several hundreds of milliseconds before the protection function is activated.
Pull out the terminal block tray, and then connect the sensing cables.
Use AWG22 to AWG16 cables when connecting to the sensing terminals. Strip approximately 10 mm of coating from the end of the cables.
Match the N and L of the OUTPUT terminal block and N and L of the SENSING terminal block.

After you finish connecting the load, turn the output on. Then, set the output voltage to the voltage that is required across the load. Because of voltage drops in the load wiring, the volt­age across the load is lower than the voltage generated by the PCR-LE Series. Use a voltmeter (or other instrument that enables you to measure voltage) to check whether the voltage across the load is the required voltage.

Checking the sensing functions (excluding the regulation adjustment function)

Turn the POWER switch on.

Set the output voltage to 10 V, and then turn the
5
output on.
Check whether a voltage of several tens of volts

is being generated.
An output being generated in this situation indicates that there are connection errors. Check whether the sensing cables are connected and whether the polarities are cor­rect. If the sensing cables are disconnected or the polarities are incorrect, a voltage will be applied across the load (at the sensing point) for approximately one second until the protection function is activated.
If the sensing cables are not firmly connected, an alarm (ALM­07: UVP or ALM-22: SENSING FAILURE) may be generated. If the polarities of the sensing cables are not correct, an alarm (ALM-00: OVP) may be generated. Connect the cables cor­rectly.
If you are installing a dedicated terminal block for sensing, check the sensing function before you connect the load to the terminal block.

In AC mode, you can simulate power supply line errors by stopping the PCR-LE Series output (to simulate power failures) and decreasing and increasing the voltage (to simulate voltage dips and pops).
You can use this to test switching power supplies and other electronic devices.
A sine wave is generated during the power line abnormality simulations. Even if you have set a special waveform, a sine wave will be generated as soon as you execute the power line abnormality simulation.
You can set these values while output is on or off.
T4=0 V(T3)=0
Parameter Description T1 This is the voltage regulation start time or the voltage regu-
lation start phase. This is the time or the phase from the waveform’s posi­tive zero crossing (the point where the signal crosses the zero axis) to the point where voltage regulations - such as increases or decreases - start to occur.
T2 This is slope time 1.
For pops, this indicates how much time is required to raise the voltage to the pop voltage. For dips, this indicates how much time is required to lower the voltage to the dip voltage.
T3 This is the voltage regulation time.
For pops, this indicates the length of time that the voltage will be kept at the voltage that it has been raised to (the pop voltage). For dips, this indicates the length of time that the voltage will be kept at the voltage that it has been lowered to (the dip voltage).
T4 This is slope time 2.
For pops, this indicates how much time is required to lower the voltage from the pop voltage to the voltage that is in use during the period indicated by T5. For dips, this indicates how much time is required to raise the voltage from the dip voltage to the voltage that is in use during the period indicated by T5.
T5 This is the return time or the number of return cycles.
This indicates how long (either as a length of time or as a number of cycles of the present frequency) the voltage will be kept at the level that it returns to after a pop or dip is completed.
T3VOLT This is regulated voltage.
For pops, this is the voltage level that the voltage will be raised to (the pop voltage). For dips, this is the voltage level that the voltage will be lowered to (the dip voltage).
LOOP This is the number of repetitions.
This indicates the number of times that the sequence of steps defined by T1 to T5 will be repeated.

Voltage regulation start polarity
You can set the zero crossing (the time at which the voltage becomes zero) that will be the reference for T1 to positive zero crossing or negative zero crossing by switching the volt­age regulation start polarity (POL). You can use this function to change the phase by 180 °. The PCR-LE Series displays the output voltage (waveform) of L of the OUTPUT terminal block, with N as its reference.

Status signals
Status signals are only generated during the periods defined by T2, T3, and T4 (period T3 when T2 and T4 both equal zero).
During single-phase, three-wire output or three-phase output (optional), status signals are output to the U-phase unit.
Signals are generated from the SEQ STAT OUT terminal (a BNC connector) on the rear panel of the PCR-LE Series. Use the configuration settings to set the signal polarity. “H” is approxi­mately 5 V. “L” is approximately 0 V.
The BNC connector is isolated from the PCR-LE Series’ INPUT and OUTPUT terminal blocks. However, the common line of the TRIG and STAT signals is shared internally, so it is not isolated from the BNC connector. Also, the BNC connector is not isolat­ed from the SLOT internal circuits. There is a slight time differ­ence (approximately 100 ms) between the status signal output and changes to the actual output.
Status signals may be output when you change the settings of the various parameters.
Press CONFIG (SHIFT+OPR MODE) and then SIG.I/O (F3) to set the status output polarity. The status signal polarity setting is shared with the sequence function.

Using the Sequence Function

Sequence overview
A sequence is a series of settings—values such as the output voltage, frequency, and time—that are saved in advance and are then recalled and automatically carried out in order at a later time.
Sequences are groups of executable units called steps. When a sequence is executed (run), its steps are executed in order, starting with the specified starting step. A single execution of a sequence is completed after the sequence’s specified last step has been executed.
You can use the jump function to skip steps and repeatedly ex­ecute all the steps in the sequence except for those that have been skipped.
Step 0
Sequence
Step 1 Step 2
…
Step 599
The maximum number of steps is 600.
Step’s signal change (ramp)
To change the frequency or voltage linearly over the specified time, select “RAMP ON.” To change the value as a step, select “RAMP OFF.”
If you specify “RAMP ON” in step 0, the signal will change lin­early from the current voltage or frequency.

Steps are managed in terms of time.
If you set the starting phase angle, steps will start from the specified phase angle.
Phase wait time is the duration from the point when the step time of the last step has elapsed to the point where the phase angle reaches the starting phase angle. The phase wait time is dependent on frequency.

If you set both the starting and ending phase angles and spec­ify phase change, the phase will change suddenly.
If you set sudden phase change to ON, you can switch be­tween two steps according to the set phase angles. For ex­ample, if you set the step n-1’s ending phase angle to 90°, the step n’s starting phase angle to 270°, and set sudden phase change to ON, when the step time of step n-1 elapses and 90° is reached, a transition is made to step n (270° phase angle).
Jump function
The steps in a sequence are normally executed in order start­ing with the starting step. However, you can use the jump fea­ture to skip over steps and repeat sets of steps by repeatedly executing jumps.
Sequence tutorial
Appendix A in the supplied CD-R operation manual contains sequence tutorials that explain sequence creation basics, phase angle settings, sudden phase changes, and multi-phase operation.
PCR-LE series 55
You can output the same waveform regardless of whether you set the starting phase angle or the ending phase angle.
When a waveform is to be output continuously (the phase does not change suddenly) and you set both the starting and ending phase angles, the waveform may be offset by one period. To avoid confusion, we recommend that you set the starting phase angle and not the ending phase angle (FREE).

Status signal output (STAT.OUT)
Status signals are only output during the time when the step’s waveform is being output.
If you set STAT.OUT to “ON,” signals are generated from the SEQ STAT OUT terminal (a BNC connector) on the rear panel of the PCR-LE Series.
•
Trigger signal output (TRIG.OUT)
Trigger signals are output during the step’s execution time. If you set TRIG.OUT to “ON,” signals are generated from the
SEQ TRIG OUT terminal on the rear panel of the PCR-LE Se­ries for several tens of microseconds.
•
Waiting trigger (TRIG.IN)
If set to “ON,” the sequence will be paused after the previous step is finished, and the PCR-LE Series will wait for a trigger. If a trigger signal (pulse width of at least 10 μs) is received through the SEQ TRIG IN terminal, the paused is released, and the step is executed.
While waiting for the trigger, the screen shows the next step number. The elapsed time remains at zero until the next step starts.

*1. In the same step, do not turn on both the trigger wait setting and the sud-

The BNC connector is isolated from the PCR-LE Series’ INPUT and OUTPUT terminal blocks. The common line of the TRIG and STAT signals is shared internally, so it is not isolated from the BNC connector.
The remote control function (excluding LAN remote control) also shares this common line. If you are using a desktop PC to control the PCR-LE Series remotely, the communication signal line of the PC is grounded, so the BNC connector will also be set to ground potential. If the signal line that is connected to the BNC connector has an electrical potential compared to ground, the connected device or the PCR-LE Series may be damaged when a current flows through the signal line.
There is a slight time difference (approximately 100 µs) be­tween the trigger signal output and changes to the actual out­put.
Trigger signals may also be output when you change the con­tents of a sequence.
For signal I/O, high level signals are approximately 5 V, and low level signals are approximately 0 V. For signal input, opening the terminal is equivalent to applying a high level signal, and shorting the input is equivalent to applying a low level signal.

Jump function
The steps in a sequence are normally executed in order start­ing with the starting step. However, you can use the jump fea­ture to skip over steps and repeat sets of steps by repeatedly executing jumps.
If the step execution time of the jump origin or jump destination step is less than 500 ms, the peaks of the output voltage wave­form of the step that will be executed next may be clipped.
The PCR-LE Series automatically adjusts the power supply volt­age (Vcc) of the linear amplifier. If you set the execution time of the jump origin step to a value less than 500 ms, the PCR-LE Series cannot perform this automatic adjustment. If the peaks of the output voltage waveform are clipped, set the execution time of the previous step to 500 ms or greater, or fix the internal Vcc.

Setup example for making sudden phase changes
Appendix A in the supplied CD-R operation manual contains se­quence tutorials that explain sequence creation basics, phase angle settings, sudden phase changes, and multi-phase opera­tion.
First, set the ending phase angle of the step immediately before the sudden phase change to 90 deg. If the sudden phase change is set to off, the sequence moves to the next step when the phase angle reaches 90 deg after the step time of the previous step elapses, as shown below.
Lastly, set the sudden phase change to on. When the phase an­gle of the previous step reaches 90 deg, the sequence changes to the next step. The next step begins at 270 deg.
When step n-1 reaches 90 deg,

You can perform harmonic analysis of the output current. A simplified measurement method is used, so this method does not conform to standards such as IEC. For measurements that conform to the standards, use the Harmonic/Flicker Analyzer KHA3000.
If the period is set greater than the aperture time, correct mea­surements cannot be made.
The harmonic current analysis function is valid in AC mode. Press OTHERS (SHIFT+MEMORY) and then FFT (F5) to set the
order and the unit. During single-phase, three-wire output or three-phase output
(optional), press OTHERS (SHIFT + MEMORY), FFT (F5), and then 1/2 (F6), and then press the key that corresponds to the phase that you want to set.

You can generate peak-clipped sine waveforms. This is valid in AC mode and AC+DC mode.
You can use remote control to configure user-defined wave­forms. For details, see the Communication Interface Manual on the included CD-R.
The PCR-LE Series creates reference waveforms for output voltage by performing D/A conversion on the data that is stored in its internal memory. One cycle (phase angle of 360°) con­sists of 10 horizontal bits and 14 vertical bits.
The reference voltage waveform of the PCR-LE Series is a sine wave. A sine wave whose positive peak is 8191 and negative peak is -8191 is assigned.

The stored waveform data in memory that corresponds to one waveform is referred to as a waveform bank. The PCR­LE Series has 64 waveform banks. Each bank is assigned a number from 0 to 63, which is used to select the waveform. Waveform bank 0 contains a sine wave that is used as the PCR-LE Series’ reference voltage waveform. This waveform bank cannot be overwritten. In the factory default settings, all waveform banks have the same waveform (sine wave) as the one that is stored in waveform bank 0.
These settings cannot be made if you are using the synchroni­zation function.
When you turn the power off, the waveform banks from number 24 to number 63 are set to the factory default setting (a sine wave). Save these waveform banks to a USB memory device as necessary before you turn the power off.
During single-phase, three-wire output and three-phase output (optional), the same waveform is assigned to all phases.

Setting the Output Impedance

ACLOAD

The PCR-LE Series’ output impedance (output resistance) is approximately 0 Ω. Commercial power supplies have an im­pedance (resistance) of several milliohms to several ohms. You can set the PCR-LE Series’ output impedance. This enables you to simulate the same environment as that which is provided by commercial power supplies.
The impedance that is required for IEC standard tests has a prescribed inductance component, but the output imped­ance of the PCR-LE Series consists entirely of resistance. You can use the PCR-LESeries to perform rough harmonic current analyses. If you require accurate data, use the Line Impedance Network (LIN Series).
Setting Soft Starts (The voltage
rise time)
To prevent the output from being turned off (the alarm from be­ing activated) and the voltage from dropping due to the load device’s inrush current that exceeds the rated capacity of the PCR-LE Series, you can control the inrush current by having the output voltage rise gradually when the output is turned on.

Fixing the Internal Vcc

AUTOFIXED
FASTMEDIUMSLOW

Selecting the Response

To minimize loss in the linear amplifier section, the PCR-LE Series automatically adjusts the linear amplifier supply voltage (Vcc) to a level that is suitable for the output voltage. Because the response speed of the preregulator (DC power supply) that generates Vcc is slower than that of the linear amplifier, the Vcc voltage is set internally (only when the output voltage is being raised) several hundreds of milliseconds before the voltage output is changed. There will be a time lag before the output voltage is actually changed even when you frequently change the output voltage externally.
You can fix the Vcc voltage of the PCR-LE Series. This is useful when you want to prioritize the output voltage response over the product’s efficiency.
Fix the PCR-LE Series’ Vcc voltage according to the peak volt­age in the output voltage change tests.
When you fix the Vcc, the internal (power) loss increases, so the protection functions may be activated depending on the output voltage (the duration that the voltage is generated for), load conditions, and ambient temperature. Be sure to carry out tests (simulations) in advance, and check how the PCR-LE Se­ries operates.
If the Vcc is fixed and the maximum used output voltage is set lower than the peak output voltage, the maximum used output voltage setting is changed to follow the peak output voltage to prevent a malfunction.
Press OTHERS (SHIFT+MEMORY), 1/3 (F6), and then VCC (F1) to set the internal Vcc.

The PCR-LE Series uses a high-speed amplifier. Depending on the load circuits (especially in the case of capacitive loads) and the wiring conditions, the output may become unstable may oscillate.
You can set the response speed of the internal amplifier (to one of the following three levels) according to the load conditions and how you will use the PCR-LE Series.
During single-phase, three-wire output, three-phase output, master-slave parallel control (optional), only soft sensing is available.
•
High speed response (FAST)
This is only valid on the PCR500LE, PCR1000LE, PCR2000LE, PCR3000LE, and PCR4000LE.
This is mostly used in research and development, such as in special tests that require fast rise and fall speeds of power supplies. Depending on the load conditions, the output may become unstable (it may oscillate). Check the output voltage waveform before you actually perform the tests. If the output is unstable, set the response to MEDIUM or SLOW.
•
Normal speed response (MEDIUM)
This is used in power-supply-environment testing - including tests such as low-frequency immunity tests - to cover a range of frequencies from commercial power line frequencies to the frequencies used by ship and aircraft power supplies.
•
High stable response (SLOW)
This is used to provide stable power to a variety of loads. For example, this setting would be used on the power supplies at an EMC test sight. Even if a capacitor that has a large ca­pacity (such as a large noise filter) is connected to the output of the PCR-LE Series, this setting can be used to provide stable operations. This setting provides a sufficient response speed to generate commercial power line frequencies, so it can also be used in typical evaluation tests.

Using the Power Management Functions

The PCR-LE Series has the following two power management functions: a sleep function and a power-saving function
Sleep function
You can set the PCR-LE Series so that it enters sleep mode after a certain amount of time passes with its power on but no output being generated (the output is off).
When sleep mode is enabled and the specified time elapses, the internal power units turn off, which reduces power con­sumption.
“zzz...zzz...Please push ESC key” is displayed faintly on the screen (it scrolls across the screen).
Press ESC to exit sleep mode. You cannot turn the output on for the few seconds between when sleep mode is exited and the internal power units turn on (the “Busy” state).

stantly.
Power-saving function (excluding the PCR500LE and the PCR1000LE)
The PCR-LE Series (excluding the PCR500LE) is made of units. Each model contains power units that correspond to the rated output capacity.
If you are using the PCR-LE Series at less than the rated output capacity, the PCR-LE Series can operate using only the neces­sary power units. Even if you are not supplying power to a load, the power units suffer power loss. Operating the PCR-LE Series with the minimum number of power units reduces power con­sumption.
This function is invalid on the PCR500LE and PCR1000LE. Set the maximum power that you will use. If the specified power
capacity is exceeded, the protection functions will be activated. Master-slave parallel operation (option) is valid only when the
connected PCR-LE Series are of the same model.

Setting the aperture time (only when using EXT)
To use an external signal source (EXT), set the aperture time.
-> p28 If the aperture time is not set, the voltage and current that are
being output may be different from what are displayed on the panel.
The aperture time setting was added in firmware version 5.00. As a result, the function for setting the estimated minimum fre­quency that was available in firmware version 4.99 and earlier is no longer available.
Setting the internal Vcc
If you set the signal source to EXT or EXT+INT, the internal Vcc is changed to a fixed value. Set the Internal Vcc value to the voltage that you want to output (peak value) + 10 V.-> p66
If the internal Vcc is set to a value greater than the actual out­put voltage, the protection function may be activated. If the in­ternal Vcc is set to a value less than the actual output voltage, a few hundred milliseconds of response delay will occur.
Outputting the signal
After you set the signal source, polarity, and the estimated minimum frequency (EXT only), apply an external signal to the INPUT terminal.
Check that the POWER switch is turned off.

Controlling the PCR-LE through external con­tacts
Wiring
To minimize the influence of noise on the output, use a two­core shielded wire or a twisted-pair wire to connect the control terminals and the external contact. Make the wires as short as possible. Susceptibility to the effects of noise increases as the wires get longer. When wires are long, proper operation may be hindered even if a cable with anti-noise measures is used.
The release voltage across pins is approx. 12 V maximum, and the short circuit current is approx. 8.5 mA maximum. (The inter­nal circuit is pulled up to 12 V through 1.3 kΩ.)
Use parts with a contact rating of 12 Vdc and 8.5 mA for the external contact.

Instantaneous peak current ratio (%)
The output voltage ratio is a percentage where 100 % repre­sents an output voltage of 100 V (output L range) or 200 V (out­put H range) in AC mode or DC mode.
The output current ratio is a percentage where 100 % represents the maximum rated output current in AC mode or DC mode.
The instantaneous peak current ratio is the instantaneous peak cur­rent expressed as a percentage of the rated maximum output current.
The rated output current in AC mode depends on the output conditions (output voltage, load power factor, output frequency). The rated output current under given output conditions is the value obtained by converting the smaller of the two values: the product of the output current ratios derived from fig. 1 (output voltage) and fig. 3 (load power factor) and the output current ratio derived from fig. 4 (output frequency).

Rated output capacity
This is the maximum output power capacity (in VA) that can be supplied continuously in the following ranges. For example, this is 1 kVA on the PCR1000LE.
In DC mode, this value is 70 % of the value in AC mode.
AC mode DC mode
Output voltage
Load power factor 0.8 to 1.0 NA Output frequency 0 Hz to 999.9 Hz NA
Rated output current
This is the maximum continuous output current (rms value). (Unit: A.)
The rated output current requires derating (reduction), which is performed according to the output conditions (output voltage, frequency, and load power factor).
Rated maximum output current
This is the maximum rms output current (in A) that can be sup­plied continuously in the following ranges. For example, this is 1 kVA on the PCR1000LE.
In DC mode, this value is 70 % of the value in AC mode.

Maximum peak current (AC mode)
This is the maximum continuous output current (peak value in Apeak) that the PCR-LE Series can supply when using a capacitor-input rectifier load.
Maximum peak current = rated maximum output current (rms) × 4
≤
Output voltage: 100 V to 150 V (for output L range) 200 V to 300 V (for output H range) Output frequency: 40 Hz to 999.9 Hz
Resistive load
Maximum instantaneous current (DC mode/ AC+DC
mode)
This is the maximum instantaneous output current (peak cur­rent in Apeak) that can be supplied to the load in DC mode or AC+DC mode.
Maximum instantaneous current = Rated maximum output current × 3.6
*: See p. 91,Output L range is 100 V, and output H range 200 V.
Instantaneous peak currenst (AC mode)
This is the maximum instantaneous output current (peak cur­rent in Apeak) that can be supplied to the load in AC mode.
This depends on the output range, voltage setting, and instan­taneous output voltage.
The instantaneous peak current near the peak value of the instantaneous output voltage is four times the rated maximum output current (maximum peak current), but it decreases in ac­cordance with the reduction in the absolute value of the instan­taneous output voltage.
Figs. 10 and 11 (p. 95) show “Instantaneous output voltage versus instantaneous peak current ratio” for the representative voltage settings of each range.
Instantaneous peak current ratio
This is the instantaneous peak current as a percentage where the rated maximum output current is 100 %.
Output current ratio
This is the output current as a percentage where the rated maximum output current is 100 %.

Output voltage ratio
This is the output voltage as a percentage where 100 V for the output L range or 200 V for the output H range is 100 %.
Output voltage waveform distortion ratio
This is the total harmonic distortion (in %) of the output voltage waveform when the output voltage is between 80 V and 150 V (for output L range) or between 160 V and 300 V (for output H range) and the load power factor is 1.
Output voltage response speed
This is the time duration defined by the output voltage change exceeding 10 % of the total change and then returning back to 10 % or less of the total change when the output current ratio has changed from 0 % to 100 % under the following conditions: the output voltage is 100 V (for output L range) or 200 V (for output H range) and the load power factor is 1 (in AC mode). (The unit is µs.)
(t: µs)
Derating
"Derating" means "reducing." In general, this refers to using a device at reduced maximum rated values (such as the voltage and the current) depending on the ambient conditions (such as the temperature and load).
Voltage dip
This refers to situations in which the voltage in a commercial power line drops momentarily due to the effects of lightning and other similar phenomena.
Generally, these voltage drops last for several tens of milli­seconds to several hundreds of milliseconds, and the voltage drops by 20 % to 80 %.
Capacitor-input rectier load (circuit)
This is a load whose rectifier circuit part is constructed as shown below. The rectifier circuit is used to convert the input AC voltage into the DC voltage that the device needs to oper­ate.
The peak input current is normally approximately two to four times the rms value. The conduction angle (the period that the current is flowing for) centered on the peak output voltage (phase angle of 90 deg or 270 deg) is approximately 20 deg to 90 deg.

• Fig.10 Instantaneous output voltage ratio versus instanta­neous peak current ratio (AC mode L range, excluding three­phase three-wire output)
The instantaneous output voltage is the instantaneous value of the output voltage waveform.
This shows the instantaneous peak current ratio in relation to the instantaneous output voltage when the output voltage is set to 50 V, 100 V, and 150 V.
For example, the instantaneous peak current that can be supplied when the setting voltage is 100 V is 160 % of the rated current (rms) when the instantaneous output voltage is 50 V and 280 % of the rated current (rms) when the instanta­neous output voltage is 100 V.
During three-phase three-wire output, the instantaneous peak current ratio is limited also by the instantaneous output volt­age of other phases.
• Fig.11 Instantaneous output voltage ratio versus instanta­neous peak current ratio (AC mode H range, excluding three­phase three-wire output)
The instantaneous output voltage is the instantaneous value of the output voltage waveform.
This shows the instantaneous peak current ratio in relation to the instantaneous output voltage when the output voltage is set to 100 V, 200 V, and 300 V.
For example, the instantaneous peak current that can be supplied when the setting voltage is 200 V is 160 % of the rated current (rms) when the instantaneous output voltage is 100 V and 280 % of the rated current (rms) when the instan­taneous output voltage is 200 V.

About the output and the load (Cont.)
Rated output current in AC mod (Cont.)
How the rated output current is determined on the PCR1000LE
The rated output current in AC mode depends on the output conditions (output voltage, load power factor, output frequen­cy). The rated output current under given output conditions is the value obtained by converting the smaller of the two values: the product of the output current ratios derived from fig. 7 (out­put voltage) and fig. 8 (load power factor) and the output cur­rent ratio derived from fig. 9 (output frequency).
The full scale of the load level meter of control panel is set to 1.1 times the calculated rated current or the current limit, which­ever is less.
Example
If you use the PCR-LE Series under conditions that exceed those that produce the rated output currents described below, the protection functions may be activated, which may cause the output voltage to drop, or turn off the output.
Example 1: The output voltage is 80 V (L range), the load power factor is 0.6, and the output frequency is 50 Hz.
From the fig.7, the output current ratio at an output voltage of 80 V
is 100 %. - - -(a)
From the fig.8, the output current ratio at a load power factor of 0.6
is 82.5 %. - - - (b)
From the fig.9, the output current ratio at an output frequency of 50
Hz is 100 %. - - - (c)
Example 2: The output voltage is 250 V (H range), the load power factor is 0.4, and the output frequency is 60 Hz.
From the fig.7, the output current ratio at an output voltage of 250 V
is 80 %. - - (a)
From the fig.8, the output current ratio at a load power factor of 0.4
is 65 %. - - - (b)
From the fig.9 the output current ratio at an output frequency of 60
Hz is 100 %. - - - (c)
From (a) and (b), the output current ratio at an output voltage of 250 V and a load power factor of 0.4 is
(a)×(b) = 52 % - - - - - - - - - - - - - - - - - - - - - - (d)
Because (d) is smaller than (c), the output current ratio is lim­ited by (d). Therefore, the maximum output current ratio is 78 %.
On the PCR1000LE, the rated maximum output current for the output H range is 5 A, so the rated output current under the above conditions is
5×0.52 = 2.6 A
From (a) and (b), the output current ratio at an output voltage of 80 V and a load power factor of 0.6 is
(a)×(b) = 82.5 % - - - - - - - - - - - - - - - - - - - - - - - - (d)
Because (d) is smaller than (c), the output current ratio is lim­ited by (d), which was calculated as (d). Therefore, the maxi­mum output current ratio is 82.5 %.
On the PCR1000LE, the rated maximum output current for the output L range is 10 A, so the rated output current under the above conditions is
10×0.825 = 8.25 A

Example 3: The output voltage is 80 V (L range), the load power factor is 0.6, and the output frequency is 10 Hz.
From the fig.7, the output current ratio at an output voltage of 80 V
is 100 %. - - (a)
From the fig.8, the output current ratio at a load power factor of 0.6

From the fig.9 the output current ratio at an output frequency of 10

From (a) and (b), the output current ratio at an output voltage of 80 V and a load power factor of 0.6 is
(a)×(b) = 82.5 % - - - - - - - - - - - - - - - - - - - - - - (d)
Because (c) is smaller than (d), the output current ratio is lim­ited by (c). Therefore, the maximum output current ratio is (c) =
77.5 %. On the PCR1000LE, the rated maximum output current for the
output H range is 5 A, so the rated output current under the above conditions is

As shown in figs. 10 and 11, “Instantaneous output voltage versus instantaneous peak current ratio,” the peak current sup­ply performance depends on the output range, voltage setting, and instantaneous output voltage.
Figs. 12 and 13 show the range in which peak current can be supplied (range between two solid lines) for the voltage wave­forms (broken lines) at the representative voltage settings of each range.
The instantaneous peak current near the peak value of the instantaneous output voltage is four times the rated maximum output current (maximum peak current), but it decreases in accordance with the reduction in the absolute value of the in­stantaneous output voltage. If this range is exceeded, the pro­tection functions of this product may be activated, which may distort the output voltage waveform or turn off the output.
For loads through which inrush current flows, such as trans­formers, motors, lamps, and capacitor-input rectifier circuits, check the current waveform, and provide adequate margin so that the peak current supply range is not exceeded. In addi­tion, keep the rms value of the output current from exceeding the rated output current or in the case of reverse power flow, 30 % of the rated output current.

How peak current that can be supplied is deter-
mined (for three-phase output)
Also for three-phase output, the peak current supply perfor­mance depends on the output range, voltage setting, and instantaneous output voltage as shown in fig. 10 and fig. 11, “Instantaneous output voltage versus instantaneous peak current ratio.”
If you are using three-phase four-wire output, read “setting voltage” as “setting phase voltage” and “instantaneous out­put voltage” as “instantaneous value of phase voltage” in fig. 10 and fig. 11.
If you are using three-phase three-wire output, because the phase voltages of the two phases are connected in series as shown in the following figure, the instantaneous peak current ratio is limited also by the instantaneous output voltage of the other phase. As such, the instantaneous peak current ratio when the instantaneous output voltage of the other phase is near 0 V may be lower than the rating.

About the output and the load (Cont.)
Rated output current in AC mod (Cont.)
Capacitor-input rectier loads
For electronic devices that have capacitor-input rectifier circuits in their input, when the output voltage approaches the peak output voltage, a peak current several times greater than the output current rms value flows as the output current.
Output current
As shown in figs. 10 to 13, keep the maximum peak current near the peak value of the instantaneous output voltage from exceeding four times the rated maximum output current.
*: Output L range is 100 V, and output H range 200 V.
The output current rms should not exceed the rated output current value calculated with the load power factor set to 1, as explained in "Linear load".
If you use the PCR-LE Series with an output current that ex­ceeds the rated output current (peak or rms value) specified above, the protection functions may be activated, which may distort the output voltage waveform or turn off the output.
You can only supply the maximum peak current described above without any distortions when the output voltage (the set­ting) is fixed. If the output voltage setting is changed suddenly (increased), the voltage and current waveforms may be dis­torted. Even if you are executing power line abnormality simula­tions or sequences, distortions may occur in the same manner if the output voltage is changed suddenly. To supply the maxi­mum peak current without distortions, fix the output voltage set­ting and then turn the output on.
Loads that generate surges
Some loads (for example, fluorescent lights) generate surges when the voltage is applied to the load or when the voltage is changed suddenly. When a surge occurs, the PCR-LE Series may malfunction. For this type of load, connect a noise filter to the output cable.
Special loads
If you connect a capacitor directly to the OUTPUT terminal block or the OUTPUT outlets, the output waveform may be dis­torted. In this situation, connect the capacitor to the load side of the output wiring.
Loads that draw an inrush current
For loads such as those listed below, when the voltage is ap­plied to the load or when the voltage changes suddenly, an inrush current (several times to several tens of times the normal current) flows for several cycles to several tens of cycles of the output frequency.
•
Transformer and slide transformer (SLIDAC) loads
When a voltage is applied to a transformer or a slide trans­former, an inrush current of up to several hundreds of times the normal current will flow for several cycles depending on the timing that the voltage is applied or the residual magneti­zation in the transformer.
•
Motor and lamp loads
When a voltage is applied to a motor or a lamp, an inrush current of several times to several tens of times the normal current flows for several tens of cycles to several hundreds of cycles.
•
Capacitor-input rectier loads
For electronic devices that have capacitor-input rectifier cir­cuits in their input, if the device does not have an inrush cur­rent protection (limitation) circuit, an inrush current of several tens to several hundreds of times the normal current flows for several cycles.
As shown in figs. 10 to 13, for capacitor-input rectifier loads, this product can supply maximum peak current up to four times the rated maximum output current near the peak value of the instantaneous output voltage.
For other loads, this product can supply maximum peak cur­rent up to 200 % of the instantaneous peak current ratio for the specified trip time (TRIP TIM) even if the rms value of the output current exceeds the rated output current (varies depending on the current waveform, output voltage, output frequency, and the like).
Examples of the instantaneous peak currents that can be sup­plied when TRIP is set to ENABLE, the output voltage is set to 100 V, and the output frequency is set to 50 Hz are shown in the following table.

If an inrush current that exceeds the peak currents listed above flows, the protection circuits of the PCR-LE Series will be acti­vated, which may distort the output voltage waveform or turn off the output.
Particularly for inductive loads such as transformers and mo­tors, if the protection circuit is activated and the output is turned off, a reverse voltage exceeding the voltage setting may be generated and appear at the output terminals.
