When the Load Has Accumulated Energy Such as Batteries

Connecting a load with accumulated energy, such as a battery

unit may cause current to ﬂow from the load to the internal circuit of the unit. This current may damage the unit or reduce the life of the load.

For this type of loads, connect a reverse-current-prevention diode (DRP) between the unit and the load in series as shown in Fig.2-4.

CAUTION

• To protect the load and the unit, select DRP according

to the following criteria.

1. Reverse voltage withstand capacity: At least twice the rated output voltage of the unit.

2. Forward current capacity: Three to ten times the rated output current of the unit.

3. A diode with small loss.

• Be sure to take into account the heat generated by

DRP. DRP may burn out with inadequate heat dissipa- tion.

2.3 CV Power Supply and CC Power Supply

This unit is capable of both constant voltage and constant current operation. This section describes these operations.

An ideal constant voltage power supply has zero output impedance at all frequencies and maintains a constant voltage against all types of load current variations. An ideal constant current power supply has inﬁnite output impedance at all frequencies and maintains constant current by absorbing the load resistance variations by changing the voltage.

Fig.2-6

Ideal constant current power supply

However, the output impedance of an actual constant voltage or constant current power supply is neither zero nor inﬁnite and has a frequency response. In addition, since the output has limitations in terms of maximum voltage and maximum current, power supplies are unable to maintain a constant voltage or current for all types of load current variations and load resistance variations. The following describes the relationship between the basic operations in constant voltage (CV) and constant current (CC) modes and the limit setting of the unit.

The following description assumes a power supply with a DC output of 100 V and 10 A (maximum rated output voltage of 100 V and maximum rated output current of 10A) as an example.

A resistive load of 10 Ω is connected to the output terminals of the power supply, and the output current limit is set to 5 A. In this condition, the output voltage is raised gradually from 0 V. At this point, the power supply is operating in the constant voltage (CV) mode. The

2-4 Before Using the Unit PAS SERIES

output current increases as the output voltage increases. When the output voltage reaches 50 V (that is, the output current has reached 5 A), the output voltage no longer increases even if you attempt to raise it. This is because the output current is limited to 5 A speciﬁed initially, causing the power supply to switch to the constant current (CC) operation mode. In this way, the power supply automatically switches from the constant voltage to constant current operation to prevent an overcurrent from ﬂowing. (The point at which the operation mode switches is called the "crossover point".) If the current limit is raised in this condition, the power supply returns to the previous constant voltage operation, allowing you to increase the output voltage further. If the current limit is increased from 5 A to 9 A in Fig.2-7, a voltage of up to 90 V can be output.

operation

Next, let's assume the case in which a load resistance of 4 Ω is used. The output current limit is considered to be the rated maximum output current. If you increase the output voltage from 0 V, the output current reaches the output current limit when the output voltage reaches 40 V; the power supply cannot output a voltage above 40 V. This is the limit even though the power supply is generating less than

PAS SERIES Before Using the Unit 2-5

half its output capacity in terms of power. If you wish to increase the output voltage further, the unit needs to be replaced by a model having larger current capacity. Particularly for loads into which a transient peak current ﬂows, the current must be set such that its peak does not reach (or exceed) the current limit. If the unit enters constant current operation mode even when the current is set to the rated output current, the current capacity needs to be raised.

Next, we consider a case in which a load resistance of 25 Ω is used. In this case, if the output current limit is set to 4 A or more, the power supply can output voltages from 0 V to the rated maximum output voltage in the constant voltage operation mode. The output voltage limit is set to the rated maximum output voltage under this load condition, and the output current is gradually increased from 0 A. At this point, the power supply is operating in the constant current (CC) mode. The output voltage increases as the output current increases. When the output voltage reaches 100 V, the output current no longer increases even if you attempt to raise it. If you wish to increase the current ﬂow further in this condition, the unit needs to be replaced by a model having higher output voltage. Particularly for loads that generate transient surge voltage, the voltage must be set so that the surge voltage does not reach (or exceed) the voltage limit.

2.4 Alarm

The unit is equipped with the following protection function. When the protection function is activated, "ALM" on the front panel display lights, and the OUTPUT is turned off or the POWER switch is shut down. However, the only action available when OHP is activated is turning off the OUTPUT. (See Fig.2-8.)

In addition, an ALARM signal is output to pin 20 of the J1 connector when the protection function is activated. (See Fig.2-9.)

For details on selecting whether to turn off the OUTPUT or shut down the POWER switch when an alarm is activated, see "3.2.4 Unit Conﬁguration (CONFIG)".

When POWER switch shutdown is selected, the illumination of "ALM" and the ALARM signal output is held for approximately 0.5 s.

Recovery from an alarm

• When POWER switch shut down is selected

After clearing the abnormal condition that caused the alarm, turn on the POWER switch.

• When OUTPUT OFF is selected

2.5 Grounding the Output Terminal

WARNING

The output terminal of the unit is isolated from the protecti ve grounding terminal. By connecting the GND wire of the AC power cord to the ground terminal of the switchboard, the chassis of the unit is set to ground potential (see Fig.2-10).

Consequently, the cable and load that are connected to the output terminal (including the sensing terminal) must have an insulation capacity that is greater than the isolation voltage of the unit with respect to the chassis.

In addition, pins 3 through 9 of the J1 connector on the rear panel (for analog remote control and output monitoring) are at approximately the same potential as the - (neg.) output terminal of the unit. Therefore, cables and devices that are connected to these pins must also have an insulation capacity that is greater than the isolation voltage of the unit.

For safety reasons, even if the output terminal is grounded, make sure the insulation capacity of the output terminal (including the sensing terminal) is greater than the isolation voltage of the unit. If you cannot obtain a cable with sufﬁcient rated voltage, secure adequate withstand voltage such as by

•

passing the cable through an insulation tube with a withstand voltage greater than the isolation voltage of the unit. If adequate insulation measures are not taken against the isolation voltage of the unit, electric shock may occur when grounding is poor.

• If the unit is to be remotely controlled through an external voltage source (Vext), do not ground the Vext output (leave it ﬂoating). If the Vext output is grounded in the example shown in Fig.2-11, the output is shor t-circuited (which can cause accidents).

WARNING

To prevent the possibility of ﬁre, use a load cable with sufﬁcient current capacity with respect to the rated output current of the unit.

PAS SERIES

Basic Operation 3-13

Current capacity of load cab les

Load cables must be rated to carry the maximum rated output current of the unit. If their current rating e xceeds the maximum rated output current, the cable will remain intact e v en if the load is short-circuited.

The allo w able current of a wire is determined by the maximum allo w able temperature of the cable insulation, which in turn is go v erned by a current-caused resistance loss, ambient temperature, and thermal resistance to the outside. The allo w able currents in table 3-2 sho w the capacity of current ﬂ o wing through a heat-resistant PVC wire (single wire) ha ving a maximum allo w able temperature of 60 ˚C when the wire is stretched horizontally in the air at an ambient temperature of 30 ˚C. If the condition is such that PVC wires with lo wer heat-resis tant temperature are used, ambient temperature e xceeds 30 ˚C, or the wires are b undled resulting in lo w heat radiation, the current capacity needs to be reduced.

Based on this consideration, it is better to mak e heat radiation as great as possible to allo w a lar ger current to ﬂ o w , as long as wires ha ving the same heat-resistant temperature are used. F or measures ag ainst noise in the load cables, ho we v er , installing the + (pos.) and - (ne g.) output lines side by side or b undling them together is more ef fecti v e

Because wires have resistance, v as the wire becomes longer or the current becomes lar the v

The remote sensing function is used to reduce the inﬂ uence of v oltage drops due to the load cable resistance and stabilize the output v oltage across the load.

The remote sensing function of this unit can compensate up to approximately 0.6 V for a single line. Select a load cable with suf ﬁ cient current capacity so that the v oltage drop of the load cable does not e xceed the compensation v oltage.

WARNING

3-20 Basic Operation

The voltage drop compensation is approximately 0.6 V for a single line. However, if remote sensing is performed near the maximum output voltage, the output of the unit is limited by the maximum voltage (105 % of the rated output voltage).

WARNING

For sensing cables, use cables with a higher voltage rating than the isolation voltage of the unit. For details, see "2.5 Grounding the Output Terminal" Protect the uncovered section of the shielded wire by using insulation tubes with a withstand voltage greater than the isolation voltage of the unit.

• To turn on/off the power supplied to a load using a mechanical switch, provide additional switches between the sensing wires as shown in Fig.3-6 and turn on/off the power and remote sensing cables simultaneously. Be sure to turn off the OUTPUT switch or POWER switch before turning on/off the mechanical switch.

CAUTION

If the sensing wires come loose , the output voltage across the load cannot be stabilized and may cause excessive voltage to be applied to the load. Securely connect the sensing wires such as by using crimp ter

minals .

CAUTION

•

Use a capacitor (C) whose withstand v oltage is greater than or equal to 120 % of the unit's rated voltage .

NOTE

CAUTION

If the wiring to a load is long, the phase shift caused by the inductance and capacitance of the wiring becomes non-negligible, thereby causing oscillation. In such case, the capacitor (C) prevents oscillation.

If the load current changes suddenly to pulse form, the output voltage may increase due to the effects from the inductance component of the wiring. In such case, the capacitor (C) also prevents variations in output.

In addition, twisting the load wires reduces the inductance component, thereby stabilizing the output.

4.1.2 Controlling the Output Voltage Using External Voltage

This method is used to control the output voltage using an external voltage (Vext) in the range 0 V to approx. 10 V.

To control the output voltage using external voltage, you must set CV control of CONFIG settings to "1." For details on CONFIG settings, see "3.2.4 Unit Conﬁguration (CONFIG)".

Press the SET switch to check the preset voltage.

WARNING

• The insulation of the external voltage source (Vext) and the cable connecting it should be greater than the isolation voltage of the unit. For details on the isolation voltage of each model, see Chapter8 "Speciﬁ- cations". In addition, leave the output of the external voltage source (Vext) ﬂoating. For details, see "2.5 Grounding the Output Terminal".

• When using shielded wires for connection, protect the uncovered section of the shielded wire by using insulation tubes with a withstand voltage greater than the isolation voltage of the unit.

The output voltage (Eo) varies in the range of 0 to rated output voltage by setting the external voltage (Vext) in the range of 0 V to 10 V.

Eo = Ertg•Vext /10 [V] Vext = 10•Eo /Ertg [V]

Ertg: Rated output voltage [V]

For a portion of the 10 V, 20 V, 40 V, 60 V, and 80 V models, the products may be manufactured under the following speciﬁcations. See also Chapter8 "Speciﬁcations".

The output voltage (Eo) varies in the range of 0 to rated output voltage by setting the external voltage (Vext) in the range of approx. 0 V [0.5 V] to 10 V [9.5 V]. (The value inside brackets is the design value.)

Eo = Ertg•(Vext-0.5) /9 [V] Vext = (Eo /Ertg•9) +0.5 [V]

0.5 ≤ Vext ≤ 9.5 [V]

PAS SERIES Remote Control 4-5

CAUTION

• Make sure the polarity of Vext is correct. Otherwise,

damage to the unit may result.

• Do not apply voltage or reverse voltage exceeding

10.5 V across the external voltage control pins. Otherwise, damage to the unit may result.

NOTE

• The input impedance across the external voltage control pins

• Use a low-noise and stable voltage source for Vext. The noise

in Vext is multiplied by the ampliﬁcation factor of the unit and appears at the unit's output. Thus, the output ripple noise may not meet the unit's speciﬁcations.

• To minimize the inﬂuence of noise on the output, use a 2-

core shielded wire or a twisted-pair wire to connect the control terminals and Vext. 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. When using a shielded cable, connect the shield to the - (neg.) output terminal. If the shield needs to be connected to the Vext side, see next page " Connecting the Shield to the Vext Side".

Chapter. 5 Parallel and Series Operation

The output voltage can be increased by connecting PAS series power supplies with the same output rating in series and operating them in master-slave series mode. Additionally, the output current can be increased by connecting PAS series power supplies with the same output rating in parallel and operating them in master-slave parallel mode.

In a master-slave system, one of the connected units is made a master and all others slaves. The master is used to control the all the connected power supply units.

The maximum number of connectable units including master and slave devices varies depending on the model as follows.

5.2.2 J1 Connector Connection (Parallel Operation)

For master-slave parallel operation, two units are connected as shown in Fig.5-6.

The maximum output current during master-slave parallel operation is equal to the number of units connected in parallel multiplied by the rated output current of a single unit.

Connecting the signal wires (parallel operation)

The connector needed to connect the J1 connector is not provided. For detail, see "4.1.1 About the J1 Connector" .

WARNING

Connection procedure

• To prevent the possibility of electric shock, be sure to use the protective cover on the sockets.

Decide the po w er supply that is to be the master unit.

Connect the J1 connectors on the rear panel as sho wn in Fig.5-6 .

When connecting more than tw o sla v e units, repeat the steps for connecting sla v e units 1 and 2.

WARNING

CAUTION

When you are done with the connection, be sure to

•

attach the output terminal cover to prevent the possibility of electric shock.

•

When connecting the output ter minal to the chassis terminal, be sure that the output terminal of the same polarity (+ or -) for each unit is connected to the chassis terminal. If you connect the output terminal of different polarities for each unit, the output is shortcircuited through the GND cable of the AC power cord. This will result in failure to obtain proper outputs and will burn the cable connected to the chassis.
