NKGY-DA CNC self-cooling fully sealed high frequency power supply
It adopts a fully-sealed self-cooling structure without a cooling fan, which can avoid acid mist corrosion. The power supply has good anti-corrosion performance and long life. It can be directly placed on the side of the plating tank. Therefore, it is particularly suitable for electronic plating. The power supply uses a power field effect tube (MOSFET) as the rectifier element. Because the MOSFET has a very small on-resistance (a few M ohms/CM2), it can greatly reduce the conduction loss of the rectifier circuit, thereby improving the whole machine Efficiency (95%). Since the on-resistance of the MOSFET is very small, the heat loss of the rectifier circuit is very small, and the temperature rise of the device is very low. For this reason, the power supply can be made into a self-cooling fully sealed, and the enclosure protection level can reach IP54, which is very beneficial to the long-term power supply. life. This is 3 to 5 times longer than the life of air-cooled power supplies. For this reason, the power supply is a very good high-frequency switching power supply for electronic plating.
