Centralised multi-output power supplies are the standard power distribution method for analogue CCTV systems: instead of running mains cable to each camera position or using individual transformer supplies at each camera, a single multi-output PSU in the head-end cabinet distributes 12V DC to all cameras via the DC camera power cable.
The 10A total output of the 16-way unit is the appropriate current rating for installations powering up to 16 standard analogue cameras drawing typical standby and operating currents. For installations with a higher camera current load, the 20A variant (HAY-PSU1612-20A) provides greater headroom for cameras with higher draw such as motorised varifocal cameras, illuminated cameras, or cameras with heating elements.
Individual fusing per output is an important installation feature: if a camera power cable develops a fault or short circuit, only the fuse for that output blows, leaving the other 15 cameras unaffected. Without individual output fusing, a single cable fault could take down the entire PSU output and all connected cameras simultaneously.
The metal case provides physical protection for the PSU in the equipment cabinet and allows the unit to be DIN rail or surface mounted in the head-end location alongside the DVR.
For CCTV installers powering analogue camera systems across London and the UK where a 16-output 10A centralised power supply is the correct specification for the camera count and current load, the Haydon HAY-PSUMULTI-10A provides the standard head-end CCTV PSU.
Key Features
- 16 individually fused outputs: a single camera fault does not affect others
- 10A total output for installations up to 16 standard analogue cameras
- Metal cased: robust enclosure for head-end cabinet installation
- Central 12V DC distribution: eliminates per-camera transformer supplies
- Appropriate for standard analogue CCTV cameras at typical current draw
- For higher loads use HAY-PSU1612-20A 20A variant
