Features:
- Manufacturer manual names 620-0036 as selectable 115/230 VAC supply.
- Occupies two defined processor-rack slots and includes battery backup.
- Voltage shorting board and input-specific slow-blow fuses require checking.
Honeywell's IPC 620-25/35 User Manual identifies 620-0036 as the AC-input processor power supply module, distinct from 24 VDC-input 620-0047. It mounts in H/I of the 620-25 or J/K of the 620-35 and powers the processor rack. The manual describes a lithium battery for memory and register backup, a front POWER indicator and a BATTERY PASS indicator. It states a 15 A maximum +5 VDC supply for processor-rack modules and 300 mA of +12 VDC for optional equipment. Those ratings should be checked against the actual installed rack loading.
The manual says a yellow shorting board inside the side cover selects 115 or 230 VAC and documents 2 A slow-blow fuse use for 115 VAC versus 1 A for 230 VAC. A 1988 manual is not a substitute for current electrical safety requirements, plant isolation practice or item-specific inspection. Record the incoming supply, selector, fuse, processor rack, battery state, cable terminations and diagnostics before work. Preserve program and data backups. After a verified replacement, confirm voltage selection and wiring under qualified procedures, restore power in the approved sequence and verify controller diagnostics and memory retention.
The 620-0036 Honeywell IPC 620 AC Processor Power Supply Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The Honeywell manual identifies 620-0036 as a processor power supply accepting user-selected 115 or 230 VAC. It is not the 24 VDC-input 620-0047. The module occupies two rack positions, H/I in the 620-25 and J/K in the 620-35. Confirm exact label and rack before obtaining a spare.
Honeywell describes a yellow shorting board beneath the side cover for AC voltage selection. It documents a 2 A slow-blow fuse for 115 VAC operation and a 1 A slow-blow fuse for 230 VAC. These are manual-era technical details, not permission to work energized. Qualified personnel must check incoming power, selector, fuse and current safety procedure before energizing.
The supply houses a lithium memory-backup battery and provides processor-rack DC power. The manual quotes a maximum 15 A at +5 VDC and 300 mA at +12 VDC. Verify actual rack loading and battery condition, protect control-program and data backups, and confirm the POWER and BATTERY PASS indications after replacement under approved site practice.
