EFD25 5KV DCM High Voltage Flyback Switching Power Supply Transformer

Short Description:

It is a high voltage switching power supply transformer that can provide users with a high-voltage output above 5KV. The product adopts a safe and reliable design scheme for high-pressure working conditions. Among them, the high-voltage output end adopts a slotted structure to reduce the voltage difference between adjacent windings, and at the same time adopts a potting process to further improve the insulation withstand voltage capability. The product is compact in design, low in height, takes up little space, and is easy to install.
