Desktop chassis power supply board converting 115 V AC to 12 V or 24 V DC
The ALTRONIX AL600ULXB is a PCB circuit board that converts 115 V AC mains into regulated 12 V DC and 24 V DC outputs. It is designed for integrators and technicians who need a compact power source for access-control panels, CCTV equipment or similar low-voltage systems.
Mounting uses standard PCB standoffs and the screw terminals accept stripped wire without special tools. The main difficulty is verifying polarity before power-up because reversed DC leads can damage connected devices. Adequate ventilation around the board must be provided to prevent thermal shutdown under continuous load.
Dual 12 V and 24 V rails supply the rated output for typical security and automation loads such as door strikes, readers and cameras. The board reaches its limit when the combined draw approaches the maximum rated current, at which point voltage sag or protection tripping will occur. It is not suited for high-power motor drives or multi-device racks that exceed the specified output capability.

Measure the output terminals with a multimeter set to DC volts; you should read approximately 12 V on the 12 V-DC rail and 24 V on the 24 V-DC rail when the 115 V-AC input is live.
The package contains the PCB circuit board only; you will need to provide a 115 V-AC mains connection, an enclosure or chassis, mounting hardware and any load-side wiring.
This single board provides both 12 V-DC and 24 V-DC simultaneously, so no separate version choice is required — use the rail that matches your load.
