Features:
- Selectable 120 V or 220/240 V input
- 1775-CAP processor-chassis connection
- Three-stage AC and DC indication
Allen-Bradley 1775-P1 is the mains power source for a PLC-3 processor chassis.
The selector, jumpers, and input terminals adapt the supply to the documented low- or high-voltage range.
AC ON, AC OK, and DC OK indicators divide a startup fault into source, input-level, or internal-output stages.
Apter Power can assist with 1775-P1 label review, cable scope, official wiring literature, quotation details, and pre-shipment checks.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- The 120 V setting uses the documented 97–132 VAC input range.
- The 220/240 V setting uses the documented 194–264 VAC input range.
- Selector position, jumpers, terminal wiring, and measured mains voltage must agree before energization.
- The 1775-CAP cable connects the supply to the PLC-3 processor chassis.
- Cable plugs and terminal hardware should be fully seated before power is applied.
- Protective grounding remains part of the approved installation rather than an optional commissioning step.
- AC ON shows that incoming AC reaches the supply.
- AC OK shows that the applied AC level meets the operating threshold.
- DC OK shows that the internal DC voltages are in their operating range.
- Powers the processor chassis in standard Allen-Bradley PLC-3 installations.
- Supports either documented mains range when the input configuration matches the site source.
- Powers primary or backup processors through the official separate-supply architecture.
