Appearance process. A good power supply process is also very strict, so as to ensure the batch consistency of the product. A power supply with poor quality will not be very good in appearance and component uniformity.
2. Full load efficiency. The efficiency of the power supply is the most important indicator. A high-efficiency power supply has a high energy conversion rate, which not only meets the requirements of energy conservation and environmental protection, but also can actually save electricity and money for users.
3. The output voltage ripple of the constant voltage power supply is large. The size of the ripple has a great impact on the life of the electrical equipment, and the smaller the ripple, the better.
4. Temperature rise when the power supply is working. The temperature rise affects the stability and life of the power supply, the lower the temperature rise, the better the temperature rise. In addition, it can also be seen from the efficiency aspect that the general efficiency high temperature rise will be small.
