๐ง Product Overview
The HONEYWELL 51401216-100 is a Cherokee Power System Assembly / Power System Cage, Revision D, used as part of the Honeywell Cherokee power distribution and control system. The assembly is associated with the JS-PSRB01 Cherokee power-system architecture and provides the mechanical and electrical framework for the internal power-supply components.
The assembly is identified with 51401216-100 Rev. D and FW-40-97 references. Available listings identify the unit as a Honeywell Cherokee Power System Assembly with a 100โ240 VAC input configuration and 550 W output rating.
This part should not be treated as a generic standalone 550 W power supply. The 550 W figure is associated with the installed ACX643/ACX631 power-supply configuration within the Cherokee power system.

โ Frequently Asked Questions
Q: Is 51401216-100 a standalone 550 W power supply?
A: No. It is identified as a Cherokee Power System Assembly / Power System Cage. The 550 W specification belongs to the associated internal power-supply configuration rather than meaning that the empty cage itself is a standalone PSU.
Q: What input voltage does it use?
A: The associated configuration is specified for 100โ240 VAC, 50/60 Hz.
Q: What is the associated Honeywell system model?
A: Listings identify the assembly with the JS-PSRB01 Cherokee Power System Assembly.
Q: What power-supply module is associated with it?
A: One documented configuration uses an ACX643 Rev-C, P/N 51109684-200, rated at 100โ240 VAC input and 550 W output. Other Cherokee configurations may use ACX631 variants, so the physical unit should be checked before ordering.
Q: Is 51401216-100 the same as 51401166-100?
A: No. 51401216-100 is identified as the Power System Cage/Assembly, while 51401166-100 is the Power System Backplane assembly. They work within the same Cherokee power-system architecture but should not be treated as interchangeable part numbers.
๐ Identification & Ordering Notes
Before purchasing, compare the following information with the installed unit:
- Part number: 51401216-100
- Revision: Rev. D
- Cherokee Power System / Power System Cage marking
- JS-PSRB01 system association
- Internal ACX631 / ACX643 configuration
- Power System Backplane reference
- Firmware and assembly markings
Because Cherokee assemblies can contain different PSU revisions and internal configurations, matching only the external appearance is not enough. The part number and revision on the actual unit should be used as the final identification reference.

๐ ๏ธ Maintenance & Installation Notes
Disconnect all incoming power before servicing the assembly. Confirm the AC input range and system wiring before energizing the unit.
For replacement work, photograph the existing wiring and connector positions before removing the original assembly. Check the backplane, PSU modules, connectors, mounting hardware, and visible PCB/cage markings for damage or revision differences.
After installation, verify input voltage, power-system status, output rails, and system communication according to the applicable Honeywell maintenance procedure.
