Product Introduction
When industrial power interruptions threaten system reliability, the Honeywell 900P01-0501 power supply provides a robust solution. Designed for 120/240VAC applications, this module offers a wide input voltage range of 90 to 264 VAC with a frequency tolerance of 47 to 63 Hz. Its screw-type terminals accept wires from 0.3 mm² to 3.3 mm² (#12-22AWG), ensuring secure connections in control panels and PLC cabinets.
Technical Specifications Breakdown
The Honeywell 900P01-0501 delivers consistent output rated at 58W with an input rating of 130 VA. It draws a maximum continuous current of 1.4 A and handles inrush currents up to 40 Amps peak-to-peak for 120 ms at 240 VAC. The internal non-replaceable fuse provides overcurrent protection without requiring external fusing. A critical parameter is the power supply hold-up time of 20 milliseconds at 115 VAC, 60 Hz under maximum load, which allows downstream equipment to ride through brief mains dips. Test jacks provide easy access to 5 VDC and 24 VDC for verification. Ambient temperature range is T4 rated: 0°C to 60°C.

Industry Applications
The Honeywell 900P01-0501 is ideal for process control systems, DCS cabinets, and PLC racks requiring a stable 58W auxiliary supply. In a typical petrochemical plant, this power supply maintains control loop integrity during brief voltage sags thanks to its 20 ms hold-up time. For OEM panel builders, the screw terminals simplify wiring with conductors from #12 to #22 AWG, reducing installation errors.
Installation & Setup Guidance
Mount the Honeywell 900P01-0501 on a DIN rail or panel using the provided slots. Use copper conductors rated for at least 75°C. Torque screw terminals to 0.5–0.6 Nm for reliable contact. Ensure proper spacing for airflow: keep at least 50 mm above and below the unit. Verify input voltage selection (120/240 VAC) via the voltage selector jumper if present—the module accepts 90–264 VAC automatically but confirm local mains.
Selection Guide & Purchasing Advice
Before ordering, confirm that your system requires a 58W power supply with screw terminals rather than pluggable connectors. The Honeywell 900P01-0501 is a direct replacement for legacy Honeywell power supplies in Siemens, Allen-Bradley, or Honeywell DCS systems. For bulk or hard‑to‑find automation spares, UBEST Automation offers this unit with fast handling and genuine parts. Verify ambient temperature conditions: the T4 rating ensures operation up to 60°C.
