51450991-001 | Honeywell | HC900 Switching Power Supply

The 51450991-001 (Type designation 900-01-0301) is a switching power supply unit designed by Honeywell for the HC900 controller system. Operating from a wide AC input range, it delivers continuous power across dual DC outputs to supply internal electronics and field device circuitry within host chassis configurations.

Power Input and Conversion

The power supply accepts a universal line input voltage ranging from 90 VAC to 264 VAC at 47 Hz to 63 Hz, drawing a maximum input current of 1.4 A. Internal switching circuits convert line power to provide stable system voltages under varying supply conditions.

Output Power Capabilities

The unit provides two distinct DC output rails: a 5 VDC rail supplying up to 6 A max for module logic operations, and a 24 VDC rail rated at 2 A max for field or internal peripheral power. Together, these outputs support a total continuous power capacity of 58 W.
