1. Technical description.
1.1. General description.
Stabilized DC power supply is intended for supply equipments that require stabilised voltage of
12V DC.
When
connected to fuse blocks of the LB4/xx/xx family, the power supply unit can feed more equipments (max. 4). The power
supply unit is protected against short-circuit, overload and overvoltage.
