Product Overview
The ABB SDCS‑POW‑4 (64162993) is a power supply / interface module designed for the ABB DCS drive control systems (notably for converter modules D5‑D7 in the DCS800 family). It provides the auxiliary voltages, measurement interface and signal distribution necessary for the converter electronics to function reliably.
Installed in the electronics tray of a converter, the SDCS‑POW‑4 generates all required DC voltages for the control electronics, supplies encoder/feedback circuits, provides bus‐monitoring interfaces, and supports diagnostics. This module is built to function in demanding industrial drive environments—heavy load, variable ambient conditions and high reliability requirements.

Product Description
The SDCS‑POW‑4 module acts as the backbone power and interface board within the converter electronics of the ABB DCS series. It handles the conversion of supply voltage, provides regulated DC voltage rails for control electronics, distributes encoder and feedback supply voltages, and enables measurement of key bus voltages and currents by the control logic.
Due to its critical role, the module is engineered for high reliability: a compact size, plug‑in modular form, strong protection features (overvoltage, overcurrent, short‑circuit), and a design tolerant of the thermal and electrical stresses found in large industrial drives. It sits at the top of the module frame and interfaces directly with the main control board, as per training documents.
In effect, by using this module the drive’s control boards receive stable power, accurate measurement data, and reliable diagnostics—thus improving overall system uptime and performance.
