2 TECHNICAL DESCRIPTION
2.1 PRINCIPLE OF OPERATION
When charging the Battery Charger is operating as a constant current generator until the battery
voltage reaches the voltage level set by the float voltage potentiometer. At this level the Battery
Charger is changing state to a constant voltage generator to maintain a constant voltage to the
battery.
Four DC outputs are connected directly to the battery making it possible to use the Battery Charger
and the battery in an uninterruptible power supply (UPS) configuration.
If the battery is loaded more than the Battery Charger can supply (>10A) power is taken from the
battery discharging it. In periods of less consumption the battery is recharged.
