The 900P01-0301 from Honeywell provides reliable AC-to-DC conversion for your automation system. This power supply accepts a wide range of input voltages from 90 to 264 V AC. It operates at 47 to 63 Hz, making it suitable for global installations. Furthermore, the unit delivers stable DC power to keep your I/O modules running smoothly. You will appreciate the built-in test jacks for quick voltage checks.
The Honeywell 900P01-0301 draws a maximum continuous current of 1.4 A. Its inrush current reaches 40 Amps peak-to-peak for 120 milliseconds at 240 V AC. The total input rating is 130 VA. An internal non-replaceable fuse protects the unit from severe overcurrent events. Additionally, the power supply offers a hold-up time of 20 milliseconds at 115V AC and 60Hz under maximum load. This short ride-through capability helps the system survive brief power interruptions.
This 900P01-0301 delivers 58W of output power. For easy diagnostics, the front panel includes test jacks for both 5 V DC and 24 V DC. These test points let you verify output voltages without disconnecting any wires. You can quickly confirm that the power supply is working as expected. Consequently, troubleshooting becomes faster and safer.
The unit uses screw-type terminals for all field wiring. These terminals accept wire sizes from 0.3 mm² to 3.3 mm², which corresponds to #12 to #22 AWG. First, strip the wire insulation properly. Next, insert the bare copper into the terminal opening. Then, tighten the screw firmly to secure the connection. Always verify that the input power is off before you start wiring.
The 900P01-0301 measures 137 mm in height and 72.6 mm in width. This equals approximately 5.4 inches by 2.86 inches. The unit weighs 0.82 kg. Its wider profile compared to I/O modules reflects the internal transformer and filtering components. Mount this power supply in a dedicated slot within the same chassis as your Honeywell I/O modules.
First, confirm that the main power source is completely disconnected. Next, slide the 900P01-0301 into the designated power supply slot of the backplane. Push firmly until the locking tabs engage. Then, connect the AC input wires to the screw terminals. Follow the polarity markings clearly shown on the housing. Finally, apply power and check both test jacks with a voltmeter. The green LED indicator should light up to confirm normal operation.

1. Can I replace the internal fuse if it blows?
No, the fuse is non-replaceable. If the internal fuse fails, you must replace the entire 900P01-0301 unit.
2. What happens if I connect 240V AC to this supply?
The unit accepts 90 to 264V AC, so 240V AC is perfectly safe. It automatically handles both 120V and 240V inputs without any jumper changes.
3. How do I use the test jacks properly?
Simply touch your voltmeter probes to the 5V or 24V jack and the common (COM) jack. You will get an immediate voltage reading without exposing any live wires.
4. Why does this power supply weigh more than I/O modules?
The 900P01-0301 contains a transformer and larger filtering capacitors. These components add weight but provide clean, stable DC power for the entire system.
5. Can I use this supply outdoors or in wet locations?
No, this unit is designed for indoor industrial control panels only. Protect it from moisture, direct sunlight, and extreme temperatures.
