1. Technical description.

1.1. General description.

Stabilized DC power supply is intended for supply CCTV cameras that require stabilised voltage of 12V DC. The unit has a
cable with a DC5.5/2.1 plug. When connected to fuse blocks of the LB4/xx/xx or LB8/xx/xx family, the power supply unit can feed
more cameras (max. 4 or 8). The unit is protected against short-circuit and overload.
