General

The protection of electrical load against power failure is often carried out by battery backed up DC power supplies, providing electrical energy to important loads during mains supply, as well as during mains failure.

Battery backed up DC power supplies have, over several decades proved extremely reliable and very economical power supplies. The reliability of a battery backed up DC power supply is defined by the quality of the battery used, as well as the reliable control & operation of the rectifier.

Our range of battery chargers uses latest digital microcontroller based technology for precise control and also offers full range of options for meeting most stringent requirements.
