Technical Overview

The Honeywell 900P01-0401 (Part No. 51450991-006) is a high-reliability industrial switching power supply module designed specifically for the Honeywell ControlEdge HC900 controller platform. This module serves as the primary energy source for the HC900 rack, converting universal AC input into the stabilized DC voltages required for CPU operations and I/O module excitation. By providing independent 5V and 24V DC rails, it ensures that sensitive logic circuits and field-side sensors remain powered without cross-interference.

Engineered with a universal input range (90–264V AC), the 900P01-0401 is globally compatible with diverse power grids. Its compact, fanless design allows for high-density installation in control cabinets, while its dual mounting options (DIN rail or panel) provide the flexibility needed for both new builds and legacy system upgrades.
