G. Power Supply Mode/2-Stage Battery Charger (see Fig.4)
In this mode the Charger can be used as Power Supply or 2-Stage Battery Charger.
This selected mode is intended to charge the batteries with external loads such as in caravans and motor homes.
The external load can draw power from the charger while the charger is charging the battery. The charger is not affected by the
current draw being diverted by an external load as it will switch from Bulk to Float Mode.
2-Stage charger cannot completely charge the battery when the charger switches from Bulk to Float Mode and the battery will in
most cases be about 80% charged. The battery will receive the remaining charge while in Float Mode over several days.
It is highly recommended to switch to 3-Stage Charger Mode periodically when the external load is disconnected.
The external load should not exceed 50% of the maximum current draw of the charger unless the battery is fully charged. If the
Bulk LED is on most of the time then the load is too large.
G1.
Power Supply Mode
The charger can also be used as a stand alone power supply without connection to a battery
It will provide a constant voltage according to the selected Float Voltage (13.2/13.5/13.8V) and rated DC current of the charger.
It is not recommended for high surge loads in stand alone applications as the initial high surge currents can trigger the overload
protection circuit.
