Note 1: 1 minute rating between the line-input terminals and the battery charger output or LED terminals or ground.
Note 2: Continuous rating between any output terminal and chassis.
Note 3: Battery voltage = 12V or higher during charging. Below 12V (Vfoldback), 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 charger has connected the +BAT terminal to the LOAD terminal.
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 RGE300 or equiv) which alone dictates the maximum allowable RMS load current. Short-term load currents may be considerably higher. Any current above the charger's current limit is supplied by the battery.
