High-voltage withstand 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, and AC withstand voltage testing can be further categorized into industrial frequency, variable frequency, and 0.1Hz ultra-low frequency technologies. Among these, 0.1Hz ultra-low frequency technology is the most advanced and is currently recommended by the International Electrotechnical Commission.

Our new generation of ultra-low frequency high-voltage generators is an independently developed core product built on the latest technology. It features a 7-inch touchscreen, imported high-speed AD acquisition circuitry, and advanced production processes. These improvements enhance instrument quality and stability, reduce equipment volume and weight, simplify operation, and deliver cost-effectiveness far exceeding similar imported products — which often suffer from short mechanical booster lifespans, high failure rates, and excessive bulk.

1. High degree of intelligence: Adopts 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 mechanisms (over-voltage protection, high and low voltage side over-current protection) with rapid action (action time ≤10ms), making the instrument safe and reliable.
4. Safe and reliable: The controller connects to the high voltage generator at low voltage using photoelectric control, ensuring safe and reliable operation.
5. Closed-loop negative feedback: A 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 highly favorable for outdoor work.
