Product Introduction
Our next-generation VLF (Very Low Frequency) High Voltage Generator is a flagship product independently developed using advanced technical frameworks. It features a 7-inch color touchscreen, a high-performance ARM7 microcontroller, and high-speed A/D acquisition circuitry, complemented by dedicated background management software.
Engineered to exceed the performance of standard domestic models, this system offers a value-to-performance ratio that far surpasses imported alternatives. It is specifically optimized for withstand voltage testing of high-capacitance electrical equipment, such as power cables, capacitors, and large-to-medium generators or motors. The system fully complies with national power industry standards and general technical specifications for VLF high-voltage generators.

Product Feature And Application
1. Advanced technology: digital frequency conversion technology, microcomputer control, pressure rise, pressure reduction, measurement, protection, etc
2. The test process is fully automated.
3. Easy to operate: simple wiring, foolproof operation.
4. Multiple protections (overvoltage protection, overcurrent protection on both high and low voltage sides), with rapid operation (operation time ≤ 10ms)
5. Safety and reliability: the controller is connected with the low voltage of the high voltage generator, with photoelectric control, ensuring safe and reliable use.
6. The high and low voltage closed-loop negative feedback control circuit is adopted, and the output has no capacity rise effect.
7. Complete configuration: capacitive touch screen, LCD Chinese character display, automatic storage, automatic printing.
8. Large test range: 0.1Hz, 0.05Hz and 0.02hz multi frequency selection, large test range.
9. Small volume and light weight: it is very convenient for outdoor operation.
