Operation

The charger has been designed to supply current to a battery until the battery terminal voltage is equal to the set float voltage. After this it will change to a trickle charge current. When the battery voltage falls, due to a load being applied and the battery being discharged, the charger will supply current to restore the voltage of the battery to the float voltage.
