GEPA ARG-24L Battery Charger and Battery Group
User Guide
1. General
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.

requirements.
4. Usage
4.1. Turn On and Off
Device may turn on after proper montage and wiring.
To turn on, follow these steps:
1. Switch AC MCB position to ON
2. Switch DC MCB position to ON
To turn off, follow these steps:
1. Switch DC MCB position to OFF
2. Switch AC MCB position to OFF
4.2. Control Unit and Settings
GEPA ARG-24L Series Battery Charger & Battery Group’s control unit, BCC-2
Control Unit, provides human machine interface.
Output voltage and current is adjustable; output voltage and current live
measurements and alarm indicators are available through control unit.
To adjust settings parameters follow steps at the below:
1. Press button.
2. Voltage display blinks. It displays adjusted voltage output value. Press up or
down buttons to adjust.
3. Press button again to save new parameter.
4. Current display blinks. It displays adjusted float current output limit value.
Press up or down buttons to adjust.
5. Press button again to save new parameter.
In case of high current demand –like deep discharged battery group or any device requires high current–output voltage
might be lower than adjusted.
Device can display battery group voltage without AC supply voltage. Press Test button to make the device to display battery group
voltage while AC supply voltage not applied.
4.3. Alarm Function
Device has an alarm contact output. NO alarm contact trips in case of:
High(240 VAC) or low(190 VAC) AC supply voltage
High(30 VDC) or low(20 VDC) DC output voltage
Leakage between DC output and earth
Output current is higher than adjusted output current value
