ALTRONIX AL624 Linear Power Supply

The ALTRONIX AL624 is a linear power supply and charger that converts low voltage AC input into regulated DC output for security installations. It delivers 1.2 amps continuous current at 6 VDC or 12 VDC and 750 mA at 24 VDC. The unit includes a built-in charger for sealed lead acid or gel backup batteries and automatically switches to battery power when AC mains fail. It is intended for access control, security and CCTV systems that require reliable uninterrupted power.

Surface Mount Base for Security Builds

The supply mounts on a surface and provides selectable 6, 12 or 24 VDC outputs to match the voltage needs of connected cameras, controllers or locks. Its integrated charger maintains a backup battery so the load stays powered during mains outages without extra switching hardware. The single unit replaces a separate power supply, charger and changeover module, simplifying wiring and reducing enclosure space. Installers should verify the load current stays within the rated output for the chosen voltage setting.

Thermal and Power Characteristics

As a linear regulator the AL624 dissipates excess voltage as heat, so the enclosure should allow adequate airflow around the surface mounted base. The supply draws low voltage AC from a transformer and converts it with typical linear efficiency, meaning power draw from the mains rises with load current and voltage differential. No fan is fitted so operation is silent, making it suitable for quiet office or residential security cabinets. The automatic battery switchover adds no audible noise during transition.

Questions about this item

How much current does the AL624 deliver at 24 VDC before the output sags?

The unit supplies 750 mA continuous at 24 VDC; sustained loads above that level will cause the voltage to drop.

Does the AL624 run hot or make noise when it powers a lock all day?

As a linear supply it dissipates the voltage difference as heat, so the enclosure becomes warm during continuous operation; there is no fan, so it remains silent.

What battery must I already have for the AL624 to keep a door strike running during a mains failure?

A sealed lead-acid or gel backup battery (6 V, 12 V or 24 V to match the output setting) is required; the built-in charger maintains it automatically.
