Overcurrent - EM TEST compact NX5 Series Operation Manual

EM TEST

12.6. Overcurrent

Power switches
The power switches are electronically
protected against overload and short-
circuits. The nominal current of the
switches is 25 A.
Special protection requirements of the
EUT must be separately assured by the
user.
Inrush currents of  = 500 A are
permitted. To avoid higher inrush currents
of the EUT an electronic control limiting
the inrush current is incorporated in the
device.
Over-voltage generated by connecting or disconnecting additional loads will be limited internally by varistors in
parallel to the electronic switch.
Occurs an overcurrent during a test, The PF switches will switch off immediately and the display shows:
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:
1. Disconnect the short circuit and make sure to remove the failure.
2. Press OK. This will switch on the PF switch again and returns the power to the EUT output.
3. Continue in the start menu with START.
