DESCRIPTION OF FUNCTIONS
The charger is fully automatic and programmed for advanced
charging of lead-acid batteries between 20 and 300 Ah. The
integrated safety functions that are intended to limit overcharges
could interrupt the charge process when charging larger batteries.
This applies especially when charging batteries that are larger than
approx. 360 Ah.
The unit can be used both as a battery charger and power supply.
The power supply is activated by selecting 13.7 V Supply, which
provides a constant 13.7 V voltage at max. 15 A. This mode is also
used for maintenance charging 12 V batteries.
This product is equipped with a temperature compensator,
because temperature is highly significant for batteries’ ability to
receive charge. The thermal sensor is integrated in one of the
terminal clamps. Thanks to our temperature compensation, the
common problems involved in insufficient charging in cold weather
and overcharging at high temperatures are eliminated.
The charging curve is shown on the accompanying diagram,
which shows how the charge is split into five different steps
that are adapted to the battery type and size.
The charger must be connected to the battery as described in
‘getting started’. After it is connected, it will charge the battery and
maintain it fully charged with the continual maintenance charging
as long as it is connected to the mains power. In order to minimise
the risk of overcharging an incorrect type of battery, the charger
