Allen-Bradley 1756-PH75 ControlLogix 125V DC Power Supply Module

Product Overview

The Allen-Bradley 1756-PH75 is a high-performance DC power supply module engineered specifically for the ControlLogix 1756 chassis system. Designed for environments where 125V DC is the primary power standard—such as electrical utilities, power substations, and large-scale energy infrastructure—this module converts a wide-range DC input into regulated backplane power. The 1756-PH75 provides robust current capacity across multiple voltage rails (1.2V, 3.3V, 5.1V, and 24V DC), ensuring that high-density I/O configurations and advanced communication modules receive stable, noise-free energy. With a high isolation rating of 3500V RMS and integrated fault protection, it maintains the integrity of the ControlLogix PAC (Programmable Automation Controller) even under harsh electrical conditions.
