Cooling Method	Forced air-cooled: 65CFM (Internal DC fan), when the temperature of radiator is over 85, the output begins to derate; when the temperature of radiator is up to 95, the output will derate to 60%; when the the temperature of radiator is over 95, the device will close.
Protection	Input Overload	Dc<130±5V, device will close automatically
	Input Underload	Dc>300±5V, device will close automatically
	Output Overload	Vdc≥60±1V, device will alarm to close, which need to manually re-start after the fault removed
	Output Short-circuit	Retraction limiting, recover automatically after the fault removed.
	Over temperature	When the temperature of the case is (85±5), the rectifier begins to derate; when the temperature is up to (95±5), the output will derate to 60%; when the temperature is over (95±5), the device will close and alarm.
