Description
The 1756-PA75 is a ControlLogix standard AC power supply from Allen-Bradley (Rockwell Automation), designed to deliver reliable power to the backplane of a 1756 chassis. The 1756-PA75 is externally powered by an input voltage range of 85-265V AC at 47-63 Hz, with nominal input voltages of 120V/240V AC, making it suitable for global industrial applications across various power grid standards.
The 1756-PA75 provides all regulated voltages necessary for any ControlLogix module to operate in the chassis, supplying four DC output voltages directly to the backplane: 1.2V DC at 1.5A, 3.3V DC at 4A, 5.1V DC at 13A, and 24V DC at 2.8A. The 1756-PA75 delivers a maximum output power of 75W when operated at 0…+60°C (+32…+140°F), making it the default choice for medium and larger ControlLogix systems requiring higher current capacity.

This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Electronic Crowbar Circuit: Protects against over/under voltage and current conditions by activating a short circuit/low resistance path, forcing output to zero volts to prevent damage.
Power Cycling Reset: If the crowbar circuit engages, the power supply must be cycled to reset protection.
Hold-Up Time: Maintains power during short interruptions: 2 cycles @ 85V AC, 6 cycles @ 120V AC, and 20 cycles @ 220V AC (60 Hz).
Technical notes
The 1756-PA75 mounts on the left side of the 1756 chassis and is compatible with Series B and Series C chassis, including the 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17 configurations. The 1756-PA75 has an open-style enclosure (none) with convection cooling, and operates in an ambient temperature range of 0…60°C (32…140°F) with storage temperatures from -40…85°C (-40…185°F).
