Technical description

The battery charger charges batteries that are used on board vehicles to generate
power or supplies them with a retention voltage so that they do not discharge. It is
automatically charging the batteries and maintaining them with float voltage after
charging has finished. Therefore the battery charger can be plugged in during
longer periods of time without damaging the batteries.
A control lamp on the device enables constant monitoring in the battery charger.
The device has the following protective systems:
•
Overvoltage protection
•
Overheating protection
•
