Features:
- •85 to 265V AC input for standard ControlLogix chassis
- •Maximum combined backplane output of 75 W
- •Left-side chassis mounting across five standard chassis sizes
1756-PA72 converts a wide-range AC source into the backplane power required by a standard ControlLogix chassis.
Selection should follow the chassis series, installed module list, total wattage, and individual 5.1 V and 24 V rail demand.
Field replacement planning should preserve source, wiring, torque, grounding, isolation, and controlled restart records.
Availability is subject to Apter Power's current inventory and sourcing confirmation.
