ABB DSSR 170 48990001-PC Power Supply Module

DSSR 170 48990001-PC Power Supply Module

DSSR 170 is used in systems with redundant power converters. The redundancy is obtained by installing one extra regulator unit, in addition to the normal requirement to give (n+1) redundancy. Standard configuration is one DSSS 171 and three DSSR 170.

You can exchange a voltage regulator unit DSSR 170 in a live system with (n+1) redundancy without disturbing the system operation. When replacing a regulator, you must place a new unit in the same position as the one which it replaces. The upper fixing screw has a switching function; tighten it to start the regulator.

The DSSR 170 is supervised by a internal discriminator, “WATCH”, which:

• Blocks the regulator at under voltage (< +16 V),

• Signals function fault REGFAIL-N and

• Indicates function status (LIVE with green LED, FAIL with red LED). 

The output voltage and the maximum load current are set by a control circuit, “REG CTRL”.

No indication is given when the 5 V regulators are overloaded or the power fails completely.
