Honeywell 51198947-100B HPM Power Supply

The 51198947-100B is an AC input, AC/DC output power supply manufactured by Honeywell for use in UCN equipment cabinets supporting PM, APM, or HPM hardware. Designed for critical distributed control system environments, this power supply operates from an AC line voltage of 85 to 264 VAC or from a 48 VDC battery backup source, providing regulated power distribution across system modules.

Power Output and Battery Charging

When powered from the AC line, the DC output is nominally rated at 25.25 VDC at a 10 amp load, and 24.25 VDC when powered from a 48V battery source. The unit features an integrated charging circuit for the 48V battery backup system alongside a nominal 6 VAC, line-frequency output rated at a 35 milliamp load to ensure line frequency synchronization. Multiple power supplies can be operated with their outputs paralleled for system redundancy.

Environmental Performance and Operation

Engineered for industrial cabinet installations, the power supply functions across a full load operating temperature range from -20 deg C to +55 deg C. Output load capability derates linearly above 55 deg C at a rate of 0.5 A/deg C up to a maximum temperature of +65 deg C. The unit complies with all applicable directives of the European Economic Community and carries CE certification.
