Requirements: No abnormal appearance, satisfied with mechanical and electrical performance.

Slide switch cold test

Place 40 ± 2 °C. After the relative humidity of 90 to 96 degrees in the environment for 96 hours, the sample was placed in the normal environment for 1 hour and then tested.

Requirements: No abnormal appearance, satisfied with mechanical and electrical performance.

Slide switch moisture test

Place 40 ± 2 °C. After the relative humidity of 90 to 96 degrees in the environment for 96 hours, the sample was placed in the normal environment for 1 hour and then tested.

Requirements: No abnormal appearance, satisfied with mechanical and electrical performance.

With the development of fan manufacturing technology, the working stability and service life of the fan have been greatly improved, and the average time between failures is 50,000 hours.

The use of a fan to dissipate heat can reduce the bulky heat sink, greatly improving the size and weight of the rectifier, and greatly reducing the cost of raw materials. With the intensification of market competition and the decline in market prices, this technology has become the current main trend.
