Note 1: For full output current. The unit remains in regulation at considerably lower line voltages although at a lower maximum output current.
Note 2: Above +65C, the output current is reduced. Attempting to operate the unit above +85C causes the unit to shut down. The unit automatically restarts when the board ambient temperature falls below +85C.
Note 3: 1 minute rating between the line-input terminals and the output terminals or ground.
Note 4: Continuous rating between the output terminals and ground. Mounting the PCB with nylon standoffs and nylon screws increases the output isolation to 1500V.
Note 5: Output voltage = Float Voltage. At lower voltages, the maximum output current ramps up to the maximum short-circuit value
Note 6: Assumes the output is connected to a minimum recommended size battery
Note 7: This is the reverse current that the battery supplies to the charger when the line voltage is removed.
