SV01

Power Supply Module

The DC/DC power supply module supplies the entire DVS-21 with +/- 5 V. It is set up

for an input voltage of 36 V – 75 V.

At a Glance:

• DC/DC power supply to the DVS-21

• Display and forwarding of group malfunction signals

• Monitoring of the processor module CPU1

• Monitoring of the input and output voltage

• Floating contacts for external signals (e.g. power supply)

• Temperature monitoring

• Passive cooling
