Product Introduction
The Allen-Bradley 1756-PA75/B ControlLogix AC Power Supply is a high-capacity power module designed to provide stable and reliable backplane power for ControlLogix systems. With a 75 W output rating, it supports larger chassis configurations that require higher current availability for multiple processors, I/O, and communication modules.
This power supply accepts a wide input voltage range of 86–265 VAC, making it suitable for global industrial applications. It delivers a regulated 5 VDC output at up to 13 A, ensuring sufficient power for high-density ControlLogix systems.
Designed in an open-style chassis-mount format, the 1756-PA75/B connects directly to the left side of the ControlLogix rack and feeds power into the backplane. Built-in status LEDs provide quick operational diagnostics, while its robust industrial design ensures stable performance in demanding environments.
