Product Overview

The ABB SD823 is a robust and compact AC-to-DC power supply module. It’s engineered to deliver a stable 24 V DC output from either a 115 V AC or 230 V AC input, which is selectable via a switch. This flexibility makes it suitable for a wide range of global power grids. The unit is designed for DIN rail mounting, allowing for easy and organized installation within control cabinets.

A key feature of the SD823 is its ability to support redundant power applications when connected to an SS822 Voting Unit. This capability significantly enhances the reliability and availability of the control system by ensuring that even if one power supply fails, the system continues to operate uninterrupted.
