Allen Bradley 1756-PA75 Series A

The Allen Bradley 1756-PA75 Series A is an AC-input power supply for ControlLogix chassis systems. It provides the regulated backplane power needed by installed processor, communication, and I/O modules.

It is selected during rack design to satisfy current demand and maintain reliable control operation across mixed module loads.

In lifecycle replacements, matching the correct ControlLogix power-supply class is critical for rack stability and startup behavior.
