CompactLogix Power Supply

The Allen-Bradley 1769-PA2 is a CompactLogix AC power supply designed for industrial automation systems. It delivers regulated 5 V-DC and 24 V-DC outputs from a wide 85-265 V-AC input range. This unit suits control cabinets requiring reliable power for CompactLogix processors and I/O modules. It is built new to SER A series specifications for immediate deployment.

Thermal and Power Characteristics

As an ATX-type supply, it converts mains voltage to the dual DC rails with a 2 A output current rating. Normal operation sees the unit managing heat within its enclosed chassis without external cooling requirements. The wide input tolerance accommodates voltage fluctuations common in industrial environments. Power draw scales directly with the connected load on the 5 V and 24 V rails.

Included Hardware and Configuration

The package provides the power supply module itself, ready for DIN-rail mounting in a CompactLogix chassis. No separate cables, software licences or configuration tools are bundled with the unit. Installation consists of seating the module and wiring the AC input terminals to the supply. The SER A revision ensures compatibility with current CompactLogix firmware releases.

Questions about this item

How is the 1769-PA2 mounted and wired, and what step is often missed?

Snap the unit onto a DIN rail inside the CompactLogix chassis, connect 85-265 V-AC to the input terminals, then link the 5 V-DC and 24 V-DC outputs to the backplane; the step often missed is tightening the grounding screw on the chassis rail before applying power.

What maintenance or replacement will the 1769-PA2 need over time?

The internal electrolytic capacitors age with heat cycles; plan to replace the supply after several years of continuous duty or if the 2 A output drifts outside tolerance, as no user-serviceable parts are inside.

What limit appears first when the 1769-PA2 runs at full load continuously?

The 2 A combined current rating across the 5 V-DC and 24 V-DC rails is the first hard limit; exceeding it trips the internal overload protection and shuts down the outputs.
