1. General
ARG Series Battery Charger with Battery Group is specifically designed to be used in power stations
and substations. The device combines battery charger and battery group in one cabinet; provides a
compact solution for space constraint facilities.
SCR based battery charger rectifies AC voltage and to supply DC supplied components and keep
batteries charged. Charged battery group ensures DC supply continuity in case of power outage, also
provides high current demands when battery charger may not be able to handle (ex: circuit breaker
spring charging).
