250W Switching Power Supply 12V 20A 16 Channel CCTV Power Supply Box With Metal Case

The BU240 is a 16-channel CCTV power distribution box built around a 250W switching power supply. It takes 100–240V AC mains and outputs regulated 12V DC across 20A total capacity — enough headroom for a full run of analogue, HD-TVI, AHD or CVI cameras on one enclosure.

Key specs

• Output: 12V DC, 20A total, split across 16 individually fused channels
• Input: 100–240V AC mains
• Backup: built-in charging circuit for a 12V sealed lead-acid battery, with automatic switchover on mains failure
• Status: LED indicators for power and per-channel output
• Housing: lockable metal enclosure, wall-mount

Each of the 16 channels carries its own fuse. If one camera or cable develops a fault, that channel trips without pulling down the other fifteen — useful on larger installs where you don't want one bad connector taking out the whole system.

The battery backup circuit is the other reason to pick this over a basic multi-way PSU. Connect a 12V sealed lead-acid battery (not included in this listing's specification) and the unit will keep cameras powered through a mains outage, switching back automatically once power returns.

Internal terminal blocks keep the camera and battery wiring organised, which matters once you're past a handful of connections. The lockable metal case suits mounting in a comms cabinet, plant room, or anywhere the wiring needs to stay tidy and out of reach.
