① Waterproof and Moisture-proofThe potting compound (mostly silicone or epoxy) completely encapsulates the circuit, forming a dense barrier that blocks water, salt spray, acids, alkalis, and other corrosive media, allowing the power supply to operate reliably in outdoor, salt spray, and high-humidity environments. ② Thermal Conductivity and Heat DissipationThe thermal conductivity of the potting compound is 0.8-3.0 W/m·K, far higher than air. It quickly conducts heat from heat-generating components such as MOS transistors and transformers to the outer casing, effectively dissipating heat from each component and reducing temperature rise, thus extending lifespan. ③ Mechanical Fixing and Vibration ResistanceAfter curing, the potting compound becomes an elastomer, which can buffer vibrations and shocks, preventing solder joints and components from ...
