XHZG series DC hipot tester is mainly used for power line department, industrial and mining, metallurgy, steel and other enterprise power departments to conduct DC withstand voltage test or DC leakage current test on high voltage electrical equipment such as zinc oxide arrester, power cable, transformer, circuit breaker and generator.

1. The IF voltage doubler circuit is applied, and PWM pulse width modulation technology and high power IGBT devices are applied.
2. With large voltage feedback, the output voltage has high stability and the ripple coefficient is ≤1%.
3. Full-scale smooth pressure regulation, accuracy ≤0.5%, stability ≤1%.
4. The boost potentiometer starts from zero and has a 0.75 UDC1mA button with an accuracy of ≤1%.
5. The overvoltage protection is set by dialing, and the error is ±1% at a glance.
