Allen-Bradley 1756-PA75/B ControlLogix AC Power Supply
Allen-Bradley 1756-PA75/B is a Series B ControlLogix standard AC power supply for mounting on the left side of a compatible 1756 chassis. Rockwell Automation specifies an 85–265 VAC input range at 47–63 Hz and a maximum combined backplane output of 75 W from 0 to 60 °C. The supply provides current for the 1.2 V, 3.3 V, 5.1 V and 24 V backplane rails, including 13 A at 5.1 V. Rockwell lists the 1756-PA75 lifecycle status as Active. Replacement planning should verify the complete catalog number, Series B revision, chassis series, input circuit, grounding, wiring, load calculation and environmental limits.

Rockwell Automation lists the 1756-PA75 lifecycle status as Active. The /B suffix identifies Series B and must be retained during procurement. Active status does not guarantee direct interchangeability with every chassis or load. Verify the complete catalog number, chassis series, input circuit, grounding, terminal condition, environmental limits and calculated backplane current before replacement.
