Bahrain acdc power module potting requirements(1)

The potting of the acdc power module is very important. This process not only involves the protection of the power module potting acdc power module (waterproof, moisture-proof, dust-proof, anti-corrosion, etc.), but also involves the protection of the power module. thermal design.

(9) For the high-voltage module power supply, do not touch the high-voltage dangerous area during use and within 10 minutes after the power outage.
(10) Purchasing principle of module power supply: Generally, switching power supply should be selected for larger power, and linear power supply should be selected for smaller power.
(11) The module power supply cannot be forcibly dismantled, and it will be damaged if it is forcibly dismantled.

Commonly used power module potting materials are divided into three categories: epoxy resin, polyurethane and silicone rubber

Epoxies cannot be used for stress-sensitive and module sealing due to their hardness and are basically eliminated by module power supplies. However, due to its low cost, this epoxy is still used in cost-sensitive micropower supplies. Some domestic bad LED advertising screen power supply manufacturers also use this epoxy resin acdc LED advertising screen power supply module. However, due to stress problems, the failure rate of this LED advertising screen power supply is very high, and buyers are miserable.
