Belgium acdc power module potting requirements(1)

The application of module power supply in several aspects
1. Electricity, mainly integrators and meters and smart meters
2. Industrial control, industrial control field
3. Medical, medical equipment, mainly including tire protectors, monitors, etc.
4. Military industry, the military industry is a widely used aspect.

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.

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 24V input power supply manufacturers also use this epoxy resin acdc 24V input power supply module. However, due to stress problems, the failure rate of this 24V input power supply is very high, and buyers are miserable.
