The Allen-Bradley 1756-PA75R is a ControlLogix redundant power supply module designed to provide continuous and reliable power to the ControlLogix system. In addition to the standard power supply features, it supports automatic chassis load sharing between paired redundant power supplies, ensuring uninterrupted operation in the event of a single power source failure. The unit operates with an input voltage range of 85–265 VAC at 47–63 Hz and delivers a total output power of 75 W within an operating temperature range of 0 to +60 °C (+32 to +140 °F). It provides output currents of 4 A at 3.3 VDC, 13 A at 5.1 VDC, and 2.8 A at 24 VDC, making it a reliable and efficient solution for high-availability ControlLogix installations.
