1. Technical description.
1.1. General description.
Stabilized DC power supply is intended for supply equipments that require stabilised voltage of 12 V DC. When
connected to fuse blocks of the LB4/xx/xx or LB8/xx/xx family, the power supply unit can feed more equipments (max.
4 or 8). The power supply unit is protected against short-circuit, overload and overvoltage.
