There is a high-frequency noise when the switching power supply is unloaded, Due to the large output power range of the product, in order to reduce the power consumption of the switching power supply when no-load, the PWM control chip will jump some control cycles. Assume that the original working frequency is 60KHZ. If there are more skipping cycles, the working frequency will be reduced to less than 20KHZ. This Sometimes a noise audible to human ears is produced. The size of this noise is also related to the production process of the transformer1. Since the winding and paint impregnation of each transformer1's coil are slightly different, the noise of each product's operation is slightly different.\u003cbr\u003e2. There is a loud sound when the fan is running; when the ambient temperature is high, the fan may work even if it is unloaded.\u003cbr\u003eThese are normal phenomena. It is recommended to turn off the AC switch when the product is not in use! If you mind it, please do not buy it.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eNOTE:\u003c\/b\u003e\u003cbr\u003e1.
