1.*Under any conditions, the total power of the product should not exceed the rated power. When the output voltage is increased, the total output power cannot exceed the rated output power, when the output voltage is decreased, the output current cannot exceed the rated output current;

2.*When measuring the full load efficiency,the fan should be connected to an external power supply. Fan loss is not included in the input power
