28 V AC/DC Power Distribution Unit

The ALTRONIX PD4UL is a 28 V AC/DC power distribution unit designed for access-control and security installations. It provides four independently fused output circuits from a single 28 V AC or DC input. The board measures 5.25 In long, 3.25 In wide and 1.00 In high and carries UL 294 recognition.

Installation notes and common issues

Mount the phenolic or fiberglass board inside a compatible enclosure using the existing holes. Connect the 28 V supply to the input terminals and wire each load to its own fused output. The most frequent error is exceeding the per-fuse current rating or mixing AC and DC loads on the same circuit.

Pre-order checklist

Verify that your system operates at 28 V AC or 28 V DC and that the total load stays within the fuse limits printed on the module. Confirm the enclosure can accommodate a 5.25 In by 3.25 In board with 1.00 In clearance. Ensure UL 294 compliance is required for the installation.

Questions about this item

How can I verify the PD4UL is distributing power correctly after installation?

Measure 28 V AC or DC at each of the four fused outputs with a multimeter while the unit is powered.

What comes with the PD4UL and what must I source separately?

The board itself is supplied; you must provide the 28 V AC or DC source, output wiring and any enclosure.

Which PD4UL variant should I choose for a UL 294 compliant access-control system?

This single model is UL recognised to UL 294 and provides four fused outputs at 28 V AC or DC.
