Allen-Bradley 1746-P1 SLC 500 Power Supply

Description

The Allen-Bradley 1746-P1 SLC 500 Power Supply is a dedicated power module for the SLC 500 automation platform, designed to deliver stable, regulated power to rack-mounted system components. It supports dual-range line voltage inputs: 85 to 132 V AC or 170 to 265 V AC, operating at a frequency range of 47 to 63 Hz, with a typical line power requirement of 135 VA. Key electrical specifications include internal current capacities of 2A at 5V DC and 0.46A at 24V DC, plus a 200mA 24V DC user power supply current capacity with a user power supply voltage range of 18 to 30 V DC. It has a surge current rating of 20A, and requires 15A overcurrent protection from the user. The module provides 1800V AC RMS isolation for 1 second between input terminals and the backplane for enhanced electrical safety. With physical dimensions of 5.5 x 2.3 x 5.7 inches and a weight of 2 lbs (0.9 kg), it is designed for installation in 1746 chassis, with a critical pre-power setup requirement to configure input jumpers before energization.
