Note 1. 1 minute rating between the line-input terminals and chassis. Also, between line-input terminals and output terminals.

Note 2. Continuous rating between any output terminal and chassis.

Note 3. Most 10Ah batteries are spec'd at 2.5A maximum charging current during bulk or absorption mode. In float mode there is no battery maximum current spec. The charger has a reduced current limit during bulk and absorption modes while allowing full current at float voltage.

Note 4. Assumes the output is connected to a minimum recommended size battery.

Note 5. This is the reverse leakage current that the battery supplies to the charger when the line voltage is removed and the +BAT terminal is still connected to the LOAD terminal via the MOSFET switch.

Note 6. This is the reverse leakage current that the battery supplies to the charger when the line voltage is removed and the charger has disconnected the +BAT terminal from the LOAD terminal.

Note 7. The load current is fused with a polymeric fuse (Bourns RG650 or equiv) which usually dictates the maximum allowable RMS load current. Of course, any current load which exceeds the 5.0A charger limit is made up by the battery which then becomes partially or completely discharged.

Note 8. It's important to not exceed the 32V spec. A 24V solar panel can have an open-circuit voltage of almost 45V. Use only a 12V or 18V panel.
