Description

Honeywell 51198651‑100 (SPS5785) HPM Bulk Power Supply Module

 

Product Title

Honeywell 51198651‑100 (SPS5785) UCN HPM Bulk Power Supply Module, AC‑Input Regulated Power Unit for DCS High‑Performance Process Manager System

 

Product Overview

The 51198651‑100 (SPS5785) is a legacy bulk power supply module for Honeywell Universal Control Network (UCN) DCS systems. It converts wide‑range AC mains input into multiple regulated DC output rails to power HPM (High‑Performance Process Manager), APM and PM controller racks and associated I/O modules. Designed for cabinet‑mount installation inside Honeywell process control cabinets, this unit delivers stable, isolated power for continuous heavy‑duty process operation. It is widely used for spare‑part replacement, system maintenance and retrofitting of existing UCN‑based DCS installations, as original manufacturing has been discontinued.
