Start moment external interference is large
Checking scheme: disconnect large equipment and test the power module separately. It is recommended to separate the power supply products from the power supply network of large equipment to avoid starting at the same time.
Too low ambient temperature leads to smaller electrolytic capacitor capacity, and too large ESR, resulting in poor startup
Checking scheme: confirm that the ambient temperature is within the operating temperature range of the product and that the power supply is properly reduced with load under low temperature conditions. It is recommended to reduce the derating rate according to the derating curve under the condition of low temperature, and it is recommended to choose power supply products with higher output power to meet the demand of low temperature.
Output external protection TVS tube specification is (far) less than the output voltage of the product, the output external TVS tube is incorrectly connected and the capacitance is damaged.
Checking scheme: test the output voltage of the power supply product after removing TVS. TVS specification selection is generally 1.2 times of the output voltage, no special requirements are generally not added.
