Product Introduction
The Allen Bradley 1756-PA75K ControlLogix AC Power Supply is a 75-watt chassis power module developed for the ControlLogix automation platform. It converts industrial AC input power into regulated DC backplane power required for system operation. Installed on the left side of the ControlLogix chassis, it supplies energy to processors, communication interfaces, and I/O modules mounted within the rack.
The 1756-PA75K is typically selected for medium to high-density ControlLogix systems where higher internal power capacity is required. It is designed for stable performance in industrial environments and supports continuous operation in applications where system reliability is critical.
Built specifically for the ControlLogix architecture, the module integrates mechanically and electrically without additional configuration, ensuring consistent power distribution across the chassis.
