ABB SD812 Power Supply Module

The SD812 (product ID 3BSC610023R0001) is a DIN-rail power supply that converts 85-265 V AC input into a regulated 24 V DC, 5 A output. It is intended for powering control system loads within ABB automation platforms and provides short circuit and overload protection in an IP20 convection-cooled housing.

Power Conversion Characteristics

The SD812 accepts a wide-range AC input from 85 to 265 V AC at 47-63 Hz and delivers a regulated 24 V DC output at 5 A. Active power factor correction maintains a power factor above 0.95, limiting harmonic current drawn from the supply. Conversion efficiency exceeds 90% under nominal load. The output stage provides short circuit and overload protection, returning to normal operation after the fault is cleared. Convection cooling eliminates forced-air fans and the associated dust ingress path, consistent with the IP20 rating. The mean time between failures is rated above 100,000 hours.

Field Installation Guidelines

Mount the unit on a standard DIN rail inside an enclosure that maintains the IP20 environment. Verify the input supply falls within 85-265 V AC and 47-63 Hz before connection. Use screw terminals sized to the load current and torque to specification. Connect the protective earth conductor before energizing the input. Maintain clearance around the housing for convection airflow; do not block the top and bottom ventilation paths. Route the 24 V DC output wiring separately from AC input conductors. Confirm the 5 A output current is not exceeded by the connected load, including inrush at startup. Observe the -20 deg C to +70 deg C operating range at the mounting location.

Frequently Asked Questions
