In V1, overvoltage protection circuit is built-in to be operated at

115 - 140% of the rated voltage. When this function operates, in-

put should be shut off, and then wait for 2 to 3 minutes( ). Output

voltage will be recovered after applying input voltage.

The recovery time depends on input voltage.

Please avoid applying the over-rated voltage to the output termi-

nal. Power supply may operate incorrectly or fail.In case of oper-

ating a motor etc. , please install an external diode on the output

terminal to protect the unit.

Adjustment of output voltage for V1 is possible by using potenti-

ometer.

Output voltage is increased by turning potentiometer clockwise

and is decreased by turning potentiometer counterclockwise.

For a receiving inspection, such as Hi-Pot test, gradually increase

(decrease)the voltage for the start(shut down).

Avoid using Hi-Pot tester with the timer because it may generate

voltage a few times higher than the applied voltage, at ON/OFF of

a timer.

If the unit is tested on the isolation between input & output and

output & FG, output terminals must be shorted.

Series operation with V2 and V3 is available by connecting the

outputs of the unit as shown below. Output current in series con-

nection should be lower than the lowest output current of the unit.

Series operation with other model is not possible.

By adding diode externally at output side, series operation with

V1 and V2 or V3 is available. For details, please consult our sales

or engineering department.

Parallel operation is not possible.

n

When two or more power supplies are used side by side, position

them with proper intervals to allow enough air ventilation. Ambient

temperature around each power supply should not exceed the

temperature range shown in derating curve.

The operative ambient temperature is different by with/without

case cover or mounting position. Please refer drawings as below.

Note:

In the hatched area, the specification of Ripple, Ripple Noise is

different from other area.
