Description
Allen-Bradley 1756-PA50
ControlLogix AC Power Supply | 85–265 V AC Input | 60 W Output | ControlLogix Chassis-Mounted Module
Product Detailed Description
The Allen-Bradley 1756-PA50 is an AC power supply designed for Rockwell Automation’s ControlLogix programmable automation controller system. It accepts an input voltage range of 85–265 V AC and supplies power to the ControlLogix chassis backplane, supporting compatible controllers and I/O modules.The power supply provides multiple DC outputs, including 5.1 V DC at up to 8 A at 50°C, 3.3 V DC at 2 A, 1.2 V DC at 1.5 A, and 24 V DC at up to 2.5 A under specified conditions. Its maximum output power is 60 W at temperatures up to 50°C, decreasing to 50 W at 60°C. It mounts on the left side of a compatible ControlLogix chassis and is intended for industrial control-system power distribution.
