The Battery Charger - Studer COMPACT-C 1600-12 Manuel D'utilisation Et De Montage

13 „OFF" blinks. When the battery voltage gets up to 12.1V / 24.2V / 48.4V, the
Inverter switches on automatically. One minute before the Inverter switches off due to
low voltage it gives out an acoustic alarm signal. If the Auxiliary Contact has been
programmed to detect the low voltage then it synchronizes the Aux. Contact with the
alarm signal. In this way, for example, an emergency back up system can be started
without any break in the energy supply.
The low voltage is set to 11.6V / 23.2V / 46.4V. These settings are standard for most
batteries. These voltage levels are maintained by the built-in Battery-Management-
System of the COMPACT by matching the load and the battery condition.
This setting is comparable with the levels of 10.8V/ 21.6V / 43.2 which are given
for most batteries at nominal load.
All voltage levels can be programmed. See the instructions under the section on
Programming. Check with your battery supplier which voltage values should be set.

The battery charger

4.6.1 Cycle of charge
The full automatic COMPACT Battery Charger is adjusted at the factory so that most
lead-acid and lead-gel batteries can be charged to the maximum. As soon as the
minimum alternating voltage for the AC IN set on the Turning Knob 23 is available at
the input (LED 1 AC IN is lit), the Battery Charger is switched on automatically (LED
2 CHARGER is lit). The battery is fully automatically charged matching to the charge
level, the adjusted volt-age levels and the charge current. Thanks to the built-in Float
Charge System, the batteries can be left connected for unlimited time with the
Battery Charger switched on.
During the charging phase the appliances at the outlet AC OUT are continually
supplied with power (LED 8 AC OUT is lit).
The charger functions are shown in the following diagram:
