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

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

Note 3. Battery voltage = 12V or higher during charging. Below 12V, the current folds back linearly to the minimum value (at 0V).

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 (Raychem RUE300 or equiv) which usually dictates the maximum allowable RMS load current. Short-term load currents may be considerably higher but not to exceed 5.0A.

A short circuit on the LOAD terminal is a serious matter. The battery can deliver a huge current to the LOAD terminal before the fuse trips - check the resistance to ground before connecting the battery. The fuse protects wiring from melting but is too slow to keep the unit's MOSFET switch from being destroyed.
