Features
The BU240 is a CCTV power supply box that keeps the cameras running when the mains fails. It has a 250W switching power supply, regulated 12V DC output of 20A in total, and 16 fused outputs, one for each camera.
It also has a built-in charging circuit for a 12V sealed lead-acid battery, which you supply separately. If the mains drops, the box switches to the battery without a break, so the cameras on it keep powering. How long that lasts depends on the battery capacity and the load of your cameras. The box has LED indicators for power and output status, and a lockable metal wall-mount enclosure with internal terminal blocks for the camera wiring and battery connection.
It supplies 12V DC, so it suits analogue and HD-TVI, AHD or CVI cameras and other 12V devices. Add up the camera current draw from the datasheets and keep the total below 20A.
Note that this powers the cameras only. A recorder, router or switch has its own supply, so those need their own battery backup if you want the whole system to carry on recording through a power cut.
Mains and battery connections should be made by a competent person, with the box isolated.
No. The box charges a 12V sealed lead-acid battery that you buy separately.
That depends on the size of the battery and the current the cameras draw. A larger battery or a lighter load gives a longer run.
It has 16 fused outputs and 20A in total.
Not by itself. It powers the 12V camera outputs. The recorder needs its own backup supply.
