Power switch
Input channels
The input channels PF1 and PF2 are located at the rear part of the equipment. Attention has to be given to the
following:
1. The plus pole of the dc supply voltage shall be connected to the red + socket and the minus pole to the black
– socket.
2. This applies for both channels.
3. The minus input of both channels are connected internally and directly lead to the output.
4. The power switches can bear no more than a voltage of 80 Vdc. They are protected by a diode.
Power switches
The power switches are electronically protected against overload and short-circuit. The nominal current of the
switches is 32A and 200A depending on the model.
Special protection requirements of the EUT must be separately assured by the user.
Inrush currents
Inrush currents of
100A are acceptable. 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 protection
diodes.
