The full set product includes a drive board, a flyback transformer, and a voltage doubler. It adopts a 12-24V DC input. A heat dissipation fan is required for continuous operation. Its voltage doubler circuit contains a voltage divider and current limiting resistor. A user can install a 100-150kV 100μA voltmeter to show the voltage. The internal components of the voltage doubler are potted with epoxy resin.The high voltage power supply has high voltage and high power, which can be used for high voltage electrostatic electret, electrostatic adsorption, electrostatic powder coating, exhaust gas treatment and other applications.
