Power supply for access control

The ALTRONIX AL400ULPD4CB delivers 12 VDC at 3.5 A or 24 VDC at 3 A from a 115 VAC 60 Hz source. Four power-limited outputs distribute power to strikes, readers and controllers in a single steel enclosure. The unit carries UL 294, UL 603, UL 1069 and UL 1481 listings plus CUL certification. Battery leads and a cam lock are included for secure installation.

Replaces separate transformers and chargers

Installers who currently wire individual wall transformers and a standalone charger can consolidate to this multi-output chassis. The jump is worth it when a project needs both 12 V and 24 V circuits, supervised outputs and battery backup in one listed package. Projects that require only a single voltage or lack space for a 13.50 in high enclosure will not benefit from this form factor.

Sustained load behaviour

Under continuous demand the supply maintains its rated 12 V or 24 V output across all four terminals without folding back. The steel enclosure dissipates heat passively, so output voltage remains stable during extended hold-open or lock-down events. No internal fan means acoustic signature stays at zero in quiet corridors or server rooms.

Preguntas sobre este artículo

What are the enclosure dimensions for mounting the AL400ULPD4CB?

The steel enclosure measures 13.50 inches high, 13.00 inches wide and 3.25 inches deep with a gray finish.

How do I set the output voltage during installation, and what step is often missed?

Select 12VDC or 24VDC before wiring; the step often missed is confirming the jumper or switch position matches the required voltage for the connected load.

When should the backup battery leads be checked or replaced?

Inspect the included battery leads during routine system testing and replace them if corrosion, swelling or voltage drop under load is detected.
