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.

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.

Use the lower holes to attach the terminal cover that

you removed in step 3 .

Use the lower holes.

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

terminals from being exposed.

Connecting cables(PCR1000LE - PCR9000LE)

Risk of electric shock. Do not touch the terminals.

Before you connect the cables, be sure to turn the POWER switch

OUTPUT terminal block

When the load is located at a remote location

Pull out the terminal block tray, and then connect the load cables.

Check that the POWER switch is turned off.

Check that the breaker of the switchboard is off.

Pull out the terminal block tray.

Securely connect the load cables to the OUTPUT ter-

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 whose diameter is greater than or equal to the diameter of the wires used to connect the load.

PCR1000LE, PCR2000LE : M4 PCR3000LE, PCR4000LE : M5 PCR6000LE, PCR9000LE : M8

Return the terminal block tray to its previous posi-

tion.

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.

Connect the power cord of the load device to a front-

panel outlet.

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.



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.

You can monitor the present output value. When the output is off, this is nearly 0.

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.

Factory default is 0.4 s.

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).

Limit Values and Protection Functions

This product has the following limit functions and protection functions.

•

Limit Functions 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.

•

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.

Item Function Description Output off Voltage upper limit Voltage lower limit Output overvoltage protection (OVP) Output undervoltage protection (UVP) Frequency upper limit Frequency lower limit Current limit

Peak current limit

Internal semiconductor protection (OCP)

Input voltage drop protection Overload protection

Overheat protection (OHP)

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.
