Honeywell 900P01-0301 ControlEdge HC900 PS-AC 900 Power Supply Module
The Honeywell 900P01-0301, also cataloged as the 900P01-0301 Power Supply Module, operates as a dedicated hardware component for high-capacity system power conversion within Honeywell ControlEdge HC900 and PLC platforms. It converts incoming AC line power (120/240 VAC at 47-63 Hz) into regulated DC bus voltages, supplying up to 58 W of continuous power to processing units, local backplanes, and expansion I/O racks across industrial control cabinets.

Direct Logic Power Conditioning & Channel-to-Channel Isolation
The 900P01-0301 PS-AC 900 power module utilizes switch-mode regulation combined with primary-to-secondary galvanic isolation to protect backplane bus communication velocity and sensitive CPU processors against electrical noise, surges, and line transients. Channel-to-channel isolation safeguards connected I/O sub-assemblies from ground loop noise, ensuring clean voltage feeds across dense control system racks. Its efficient heat dissipation profile minimizes cabinet thermal accumulation during continuous 58 W power delivery.
Frequently Asked Questions
Q: Does the 900P01-0301 power supply support field replacement while the rack is energized?
A: No, primary AC mains supply to the 900P01-0301 screw terminals must be isolated and de-energized prior to removing or installing the power supply module to prevent electrical shock or backplane bus arcing.
Q: How are field wiring connections secured to the power module?
A: Incoming AC line, neutral, and protective earth conductors terminate directly into industrial screw terminals designed to accommodate stranded copper wiring with insulated ferrule terminations.
Field Installation Guidelines
- Mounting & Cabinet Ventilation: Secure the 900P01-0301 into its dedicated power slot on the chassis rack. Ensure a minimum clearance of 75 mm above and below the module housing (137.2 x 72.8 x 148 mm envelope) to support unobstructed natural convection cooling inside the enclosure.
- AC Supply Wiring: Route AC mains power cables separately from low-voltage analog and digital signal wiring to prevent electromagnetic interference. Strip conductor ends to 7 mm and tighten screw terminals to a maximum torque of 0.6 Nm.
- Protective Earthing: Connect a dedicated low-impedance grounding wire from the earth screw terminal directly to the enclosure's main ground bus bar. A robust earth connection is essential for the proper functioning of internal surge protection and EMI filtering stages.
