Product Overview

The ABB DSSR116, identified by part number 48990001-FK, is a specialized step-up voltage regulation module designed for critical power management within industrial automation and robotic control systems. This unit functions as a high-stability DC-to-DC converter, typically utilized to ensure consistent logic-level voltage delivery to backplanes and sensitive circuit boards. By providing a regulated 5V DC output from standard 24V DC industrial inputs, the DSSR116 maintains the operational integrity of central processing units and memory modules within a Distributed Control System (DCS). Its slot-mount architecture and ruggedized design make it an essential component for both the ABB Master system and advanced robotic controller platforms.
