The charger output current is limited to 12A.
Protection against reverse polarity connection is achieved using external fuses.

For some applications it may be necessary to vary the Control Switching Voltage of the Unit.  Example: When charging Leisure Batteries from the Engine Battery and Alternator to prevent the Engine Battery from being discharged beyond the required level when the Alternator is not charging.

The E916 Control Voltage Adjuster is an add on module that allows the Installer to adjust the Voltage at which the Charger Switches On / Off. The Voltage can be set in the range 12.3V to 13.5V

Note:
If the Input Voltage is more than 15V, the Output Voltage will rise above 14V and the battery could overcharge
