High-voltage withstand voltage testing of electrical equipment is one of the most important items stipulated in "Insulation Preventive Test." Withstand voltage tests are divided into AC and DC types. AC withstand voltage testing further splits into industrial frequency, variable frequency, and 0.1Hz ultra-low frequency technologies. Among these, 0.1Hz ultra-low frequency is the latest technology and is currently recommended by the International Electrotechnical Commission.

Our new generation of ultra-low-frequency high-voltage generators is a core product independently developed using the latest technology. It features a 7-inch touchscreen, imported high-speed AD acquisition circuitry, and advanced production processes. This design improves instrument quality and stability, reduces equipment volume and weight, simplifies operation, and delivers cost-effectiveness far exceeding similar imported products—which often suffer from short mechanical booster life, high failure rates, and large volume.

1. High degree of intelligence: Adopting digital frequency conversion technology and microcomputer control, boosting, bucking, measuring, and other test processes are fully automated.
2. Convenient operation: Simple wiring, 7-inch large LCD touchscreen, easy to operate, and friendly human-machine interaction.
3. Comprehensive protection: Multiple protection features (over-voltage protection, high and low voltage side over-current protection) with rapid action (action time ≤10ms), ensuring the instrument is safe and reliable.
4. Safe and reliable: Controller and high voltage generator low voltage connection, photoelectric control, safe and reliable use.
5. Closed-loop control: High and low voltage closed-loop negative feedback control circuit is adopted, and the output has no capacitance rise effect.
6. Accurate sampling: High-voltage current and voltage data are obtained directly through high-voltage side sampling, so the data are real and accurate.
7. Complete configuration: 7-inch capacitive touch screen, LCD English character display, automatic storage, and automatic printing.
8. Wide test range: 0.1Hz, 0.05Hz, and 0.02Hz with multiple frequency options, providing a large test range.
9. Easy to carry: The instrument is small in size and light in weight, which is very favorable for outdoor work.
