ZGF Integrated DC Hipot Tester
Product Introduction
The ZGF Integrated DC Hipot Tester is specifically designed for detecting the electrical insulation strength and measuring leakage current in power devices. It employs a high-frequency voltage doubler circuit and integrates advanced PWM pulse width modulation technology along with a voltage-current dual closed-loop feedback system. Utilizing imported high-power IGBT devices and advanced drive technology, the tester achieves high voltage stability and extremely low ripple. Additionally, the adoption of imported high-frequency high-voltage rectifier diodes makes the double-pressure cylinder more compact and lightweight.
