User Guide
GEPA ARG-24L Series Battery Charger & Battery Group is used for DC power systems of power
stations, substations or other applications where DC voltage needed. Device provides DC
voltage to system by rectifying AC voltage input and keeps batteries under charge (float charge)
in case of AC power loss to keep DC power bus alive.
GEPA ARG-24L Series Battery Charger & Battery Group is designed for applications which
require short-term high current demand. The device designed considering the requirements of
substations. Provides short-term high current demand, for like circuit breaker charging
motor, and continuously provides float charge voltage for battery group and DC power
system. Thus, it provides low-cost and ergonomic solution for such applications.
