DC Power Supplies

Choose a DC supply by the voltage and current of the load, where it mounts, and whether it must carry on when the mains fails.

Output

12V supplies, often at 13.8V nominal to charge a standby battery, power many cameras, readers and locks. 24V supplies suit door entry and some cameras, and 48V units such as the Hikvision DRL-48V240W1EN and the 150W DS-KAW150-4N serve higher-power equipment.

Mounting

The Haydon HAY-PSU12V3ABB is a boxed supply in a metal box with room for a battery. DIN-rail supplies, such as the AMG Systems AMGPSU-T12-P15 and Comnet PS-A24060, clip into a control cabinet, and the Elmdene VRS122000EB is an encapsulated supply. DMP ES501 and ES502 metal enclosures with a hinged cover protect a plug-in transformer.

Site conditions

For exposed positions, the Haydon HAY-PSUIP1X2A-12VDC is a 12V DC supply in an IP66 polycarbonate enclosure.

Battery backup and fused outputs

Haydon boxed supplies with battery backup keep security systems running through a power cut, and most have tamper detection. Elmdene FOM-4 and FOM-8 fused output modules split one supply into separately fused circuits, so a fault on one camera does not take down the rest.
