SH-EI28 is a power type low frequency transformer, which can provide a stable output voltage by connecting the mains electricity to ensure the normal operation of the board. This product has a special shell and is potted with epoxy resin because it needs to do well in moistureproof, rust protection and insulation while exhaust fans can be installed in special occasions to take away humid air.
