Chapter. 2 Before Using the Unit

CAUTION
Before using the unit, users are requested to thoroughly understand the following matters.

2.1 Inrush Current

An inrush current flows when the POWER switch is turned on. If you are planning to use several sets of the unit in a system and turn on their POWER switches simultaneously, check that the AC power source or the switchboard is of sufficient capacity.
For details on the inrush current of each model, see Chapter8 "Speci­fications".
Allow at least 10 seconds between power cycles.
Repeated on/off of the POWER switch at short inter­vals can cause malfunction of the inrush current limit-
circuit and shorten the service life of the input
ing fuse and POWER switch.

2.2 Load

Note that the output will become unstable if the following types of loads are connected.

1. When Load Current Has Peaks or Is Pulse-Shaped

2. When the Load Generates a Reverse Current to the Power Supply
3. When the Load Has Accumulated Energy Such as Batteries
2.2.1 When Load Current Has Peaks or Is Pulse-
Shaped
The current meter on the unit indicates only mean values. Even when the indicated value is less than the preset current value, the peak val­ues may actually exceed the preset current value. In such case, the unit is instantaneously put into constant-current operation mode, and the output voltage drops accordingly.
For these types of loads, you must increase the preset current value or increase the current capacity.

2.2.2 When the Load Generates a Reverse Current to the Power Supply

The unit cannot absorb a reverse current from a regenerative load such as an inverter, converter, or transformer that supplies current to a power supply. Consequently, the output voltage will increase and the output will fluctuate.
For these types of loads, connect a resistor R bypass the reverse current. However, the current capacity to the load decreases by Irp.
For resistor RD, select an appropriate resistor rated
for the power (allowing sufficient margin). If a resistor with insufficient rated power for the circuit is used, it may burn out.

However, the output impedance of an actual constant voltage or con­stant

wer 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 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

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.
Fig.2-7 Constant voltage operation and constant current
Next, let's assume the case in which a load resistance of 4 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

o
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 half its output capacity in terms of power. If you wish to increase the
PAS SERIES Before Using the Unit 2-5
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 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.

2.5 Grounding the Output Terminal

WARNING
• 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
assing t
p withstand voltage greater than the isolation voltage of the unit. If adequate insulation measures are not taken
ga
a may occur when grounding is poor.
• If the unit is to be remotely controlled through an
xt
e output (leave it floating). If the Vext output is grounded in the example shown in Fig.2-11, the out­put is short-circuited (which can cause accidents).
The output terminal of the unit is isolated from the protective ground­ing terminal. By connecting the GND wire of the AC power cord to the ground termi ground potential (see Fig.2-10).
Consequently, the cable and load that are connected to mi
nal (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.
