Allen Bradley 1746-P3 Power Supply Module

Product Introduction

The Allen Bradley 1746-P3 is a power supply module designed for the SLC 500 programmable logic controller (PLC) series. It converts standard AC input power into a regulated 24 VDC output to supply the SLC 500 chassis and its connected I/O modules.

Engineered for industrial applications, the 1746-P3 provides stable and reliable power to ensure continuous operation of automation and control systems. Its rack-mount design allows for secure installation within control cabinets, and it is capable of handling high inrush currents during startup without impacting system stability.

This module is widely used in manufacturing, process control, and factory automation where uninterrupted DC power is critical for PLC operation and overall system reliability.
