1. Technical description.
1.1. General description.
Stabilized DC power supply is intended for supply CCTV cameras that require stabilised voltage of 12 V 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.
