FAQ

Q1: Can SD831 be used in redundant configuration?
A1: Yes. Redundant applications require SS823 or SS832 diode voting units. SD831 supports both non redundant and redundant setups.

Q2: What is the hold up time during mains blackout?
A2: Hold up time is 29 ms at AC input and 120 ms at DC input. This keeps the output stable during short power interruptions.

Q3: Does SD831 have a supervision relay?
A3: No. SD831 does not include a supervision relay. For monitoring functions use external supervision devices or select other ABB power supply models with relay output.
