BR 4807 is a DC Supply System used in MV Substations, for providing stable DC to Scada Equipments, Measurement, Protection and MV Switching Equipments.

To charge the batteries efficiently, BR 4807 is designed with current and voltage regulator. It consists of 2 pieces of VRLA type batteries which are able to work on different positionings and a charger unit.

Deep Discharge Proof batteries set values is 2,23V/Cell at 20ºC. 24 Cell Battery output voltage is 54 VDC.

To provide DC rectify voltage and isolate the protection system from the network in terms of 2kV 5mA , BR4807 has a powerfull transformer whish has copper wire and “H” class temperature values.
