ABB SD822 Power Supply Module

The ABB SD822 Power Supply Module provides a regulated 5 V DC system supply from a 24 V DC input to power ABB control-system components in industrial automation. It supports parallel operation for redundancy and is designed for DIN rail mounting in ABB AC800M control systems, PLC panels, and DCS or process automation equipment. With an output current up to 10 A, it delivers reliable power while protecting the system with overload, short-circuit, and overvoltage protections. The module carries IP20 protection and operates from 0°C to +55°C, with storage from -40°C to +70°C. It is CE and UL compliant and commonly used for power supply replacement, system upgrades, and maintaining stable operation in oil and gas, power generation, and manufacturing environments where continuous power is critical. Common replacements include ABB SD823, ABB SD831, and Siemens SITOP PSU100S.
