RMU Battery Charger

About RMU Battery Charger

RMU battery charger is used for smooth power supply to switch gear unit. Offered charging system comprises of charger 1, charger 2 and battery. Blocking diode is used to combine the output of its both chargers. In case of any failure in charger 1, it is the charger 2 that takes care of remaining battery charging procedure without causing any hindrance in power supplying system. RMU battery charger is completely protected against power overload and short circuit conditions. Prolonged working life is one of the key features of this product.
