11.4. Overcurrent

Power switches

The power switches are electronically
protected against overload and short-
circuits. The nominal current of the
switches is 25A.

Special protection requirements of the
EUT must be separately assured by the
user.

Inrush currents of



= 500A are permitted.

To avoid higher inrush currents of the
EUT an electronic control limiting the
inrush current is incorporated in the
device.

Correct phase relation between PF1 and PF2

Over-voltage generated by connecting or disconnecting additional loads will be limited internally by varistors in
parallel to the electronic switch.

Overcurrent REMOVE SHORT CIRCUIT

! ON

Example overcurrent message in display

Occurs an overcurrent during a test, The PF switches will switch off immediately and the display shows:

Overcurrent REMOVE SHORT CIRCUIT ! ON

This error message appears after a short circuit at the EUT output plugs. This current can be up to 700A during
few µs and will be detect from the overcurrent detection.

For overcurrent handling proceed as follow:

Disconnect the short circuit

and make sure to remove the failure.

2. Press

F7 ON

. This will switch on the PF switch again and returns the power to the EUT output.

3. Continue in the start menu with CHANGE, START or CONTINUE.
