Information About 1746-P1

The 1746-P1 is part of the Allen-Bradley SLC 500 product family, designed to deliver consistent power for controllers and expansion modules in industrial automation. Installed at the leftmost position of the 1746 chassis, this module supplies both the backplane and user power requirements of the system. It features a CPU hold-up time of 20 ms at full load and up to 3000 ms at no load, allowing the system to continue scanning logic briefly during power fluctuations. With built-in fuse protection and an additional user-supplied overcurrent safeguard rated at 15 A, the 1746-P1 ensures reliable operation and protection in demanding environments.
