Features:
- •24 V DC source: Rockwell specifies an 18–32 V DC input range.
- •75 W combined output: All ControlLogix backplane rails together must remain within 75 W.
- •Standard chassis integration: The supply mounts on the left side of a supported 1756 chassis.
1756-PB75 converts an industrial 24 V DC source into the regulated power rails required by a ControlLogix backplane.
System planning should total the 1.2 V, 3.3 V, 5.1 V, and 24 V demand of every installed chassis module before commissioning.
Procurement review should confirm the exact 1756-PB75 catalog number, chassis series, DC source, wiring, and calculated load.
Availability is subject to Apter Power's current inventory and sourcing confirmation.

- •Input range: Use an 18–32 V DC source for the 24 V DC nominal supply.
- •Source capacity: Include the official 95 W maximum input requirement in cabinet power planning.
- •Energization: Allow for up to 30 A inrush current when selecting protection and distribution components.
- •Hold-up behavior: Rockwell specifies 35 ms at 18 V and 40 ms at 24 V or 32 V.
- •Combined limit: The total power drawn across all backplane rails cannot exceed 75 W.
- •5.1 V demand: Calculate installed module demand against the 13 A rail capacity.
- •3.3 V demand: Calculate installed module demand against the 4 A rail capacity.
- •Remaining rails: Include the 1.2 V at 1.5 A and 24 V at 2.8 A capacities in the chassis total.
- •Mounting position: Install the supply on the left side of the supported 1756 chassis.
- •Supported chassis: Rockwell lists 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17.
- •Series review: The official technical data lists Series B and Series C chassis compatibility for 1756-PB75/B.
- •Wiring check: Use 2.5 mm² (14 AWG) copper wire rated at 90 °C and apply the documented terminal torque.
