ABB SR511 (3BSE000863R1) 24V‑5V Power Regulator Module for Advant OCS / AC450 Controller System

Description

ABB SR511 (3BSE000863R1) 24V‑5V Power Regulator Module for Advant OCS / AC450 Controller System

Product Details

The SR511, part number 3BSE000863R1, is a rack‑mount DC‑DC power regulator module for ABB Advant OCS and AC450 / AC460 controller racksABB Group. It accepts 24 VDC system input and delivers stabilized 24 VDC and 5 VDC regulated outputs to supply CPU, memory chips, communication and I/O sub‑modules inside the controller unit. Rated output: 2 A for 24 V channel, 1 A for 5 V channel, tight load‑line regulation and low output ripple ensure stable power for sensitive logic circuits. It adopts Eurocard plug‑in structure for Advant backplane, supports hot‑swap replacement. Front‑panel LED indicators visualize power‑on status and fault conditions. This is an EOL discontinued hardware, widely used as original spare‑part and retrofit replacement for legacy power, petrochemical and pulp‑paper DCS racks.

Main Functions

1. Receive 24 VDC input power from rack power supply, output stabilized 24 V and 5 V DC power for controller internal logic circuits.
2. Provide reliable 5 V power for CPU board, memory chips and logic‑level peripheral circuits.
3. Supply regulated 24 V power for communication interfaces and sub‑modules inside AC450 / AC460 controller.
4. Implement over‑current, over‑voltage and over‑temperature protection; cut off output automatically under abnormal conditions to avoid downstream hardware damage.
5. Indicate module working and fault status via front‑panel LED lamps for on‑site maintenance personnel.
6. Support hot‑swap plug‑and‑play replacement to finish power‑regulator maintenance without stopping DCS control logic.
7. Suppress input‑side power‑supply ripple and interference, improve power‑supply quality for the whole controller unit.
8. Cooperate with DSPC172, SC520 and other hardware to constitute complete Advant OCS controller power‑supply architecture.
