Honeywell 51198947-100G | Power Supply Module for PM/APM/HPM

HONEYWELL 51198947-100G Power Supply

The Honeywell 51198947-100G is a dedicated UCN PM Power Supply designed for stable operation in distributed control environments. It supports PM, APM, and HPM controller families, delivering consistent output for modules installed in Honeywell UCN system cabinets. This unit was originally manufactured in the United States and is now supplied mainly as refurbished or repair-grade hardware due to discontinuation. Its regulated outputs help maintain reliable controller behavior, and its multi-range input capability makes it suitable for varied industrial power conditions. In addition, the unit is widely used in long-running DCS upgrades, where compatibility and consistent performance remain priority concerns.

The power supply accepts both AC input and an optional DC backup source, allowing continued operation during grid disturbances. Moreover, its construction supports demanding plant conditions, including high-duty cycles and continuous 24/7 operation. Many facilities continue using this model because it maintains stable power distribution across legacy Honeywell architectures without requiring major cabinet redesigns. Therefore, it remains a practical choice for operators extending the life of their installed control assets.
