Allen-Bradley 1756-PA75 is a standard ControlLogix chassis power supply for converting 85–265 V AC input power to the regulated backplane voltages used by 1756 modules.
It accepts 47–63 Hz AC and supplies up to 13 A at 5.1 V DC and 4 A at 3.3 V DC, subject to the overall chassis power curve. The unit mounts on the left side of a compatible ControlLogix chassis.
The catalog number is currently active in Rockwell Automation documentation. Verify chassis compatibility, total backplane load, branch protection, grounding and removal of input power before installation.
The Allen-Bradley 1756-PA75 may be supplied and supported by Moore Automated according to the official product lifecycle: Active/Available from OEM.

- Backplane power: 75 W maximum
- System: ControlLogix 1756
- Mounting: Chassis-mounted
- Input voltage: 85 to 265 VAC
1756-PA75 converts wide-range AC input into ControlLogix backplane power. System reliability depends on correct branch protection, grounding, chassis mounting and a verified 3.3 V/5.1 V backplane load calculation; always remove AC input before installation or removal.
Compatibility: Match the 1756 chassis, supply series, input voltage, total backplane load and redundancy requirements.
Configuration: requires chassis-side mounting, protective earth, correct AC wiring and a calculated backplane power budget.
Application: It powers ControlLogix controllers, communication modules and I/O modules through the 1756 chassis backplane.
Lifecycle: Availability is checked against the complete 1756-PA75 configuration so that an incompatible revision is not supplied.
