Why switching power supply need conformal coating?

  • March 09, 2021

Powerld has been specializing in switching power supply for 30 years and has unique insights into many applications.

Some coastal customer applications are close to the sea, and the salt fog in the air is very thick. If the switching power supply is not with conformal coating, many components will be corroded by the salt fog and fail. For such applications, our company will brush conformal coating for both sides of the switching power supply, by doing this, can greatly extend the life of the power supply.

For example, VAT-UP300S-X-60L-A, used for LED display application.

There are also some customer applications in supermarkets. Some supermarkets are dirty and there will be a lot of bugs. Bugs running into the power supply will cause some componnets to short-circuit and fail. For such applications, our company will brush conformal coating for both side of switching power supply, at the same time , Use heat shrink tubing or white glue to protect the components of the high voltage part to avoid short circuit failure caused by insect contact. These will be customized projects.

Our standard switching power supplies are also with conformal coating, such as PD-35, PD-50, PD-75, GKF-100, GKF-150, GKF-200, GKF-320, PDF-600, PDF-800 series and All Din Rail power supplies.

Switching power supplies with conformal coating can help customers reduce customer complaints and losses, powerld has always been considering customers’ applications.
