51198947-100K Honeywell | AC/DC Supply for Legacy UCN Cabinets

HONEYWELL 51198947-100K Power Supply

The Honeywell 51198947-100K is a compact industrial power supply module designed for stable operation in Honeywell PM, APM, and HPM automation systems. It delivers reliable AC/DC regulated output to multiple processors and control modules used across Honeywell’s distributed control environments. Many facilities continue using this model because its electrical behavior matches legacy system requirements without forcing major cabinet modifications. Moreover, its wide input range allows plants with mixed power conditions to maintain consistent DCS performance.

This module originates from Honeywell’s U.S. manufacturing line and is commonly supplied as refurbished or FOR PARTS / REPAIR, depending on inventory. Its robust design supports long production cycles, and many engineers value its predictable operation during load fluctuations. In addition, support for redundant configurations helps reduce unplanned downtime, making it suitable for plants operating continuous 24/7 processes.
