Product Features

1. Adopting microcontroller control, 7-inch large screen touch operation, imported photoelectric data transmission, digital frequency conversion, automatic testing, real-time Chinese character prompt during the process, and real-time display of output waveform
2. Drawing inspiration from the design concepts of the United States and Europe, using our company's developed single link structure and imported high permeability iron core production, not only has strong power, high efficiency, and strong carrying capacity, but also has simple wiring, convenient operation, and is not prone to errors, especially reducing the overall weight and making transportation more convenient.
3. Rated voltage: 30KV, 40KV, 50KV, 60KV, 80KV, 90KV, etc. Current, voltage, and waveform data are directly sampled from the high-voltage side, so the data is accurate.
4. Comprehensive protection: multiple protections (overvoltage protection, high and low voltage side overcurrent protection), quick action (during action) ≤ 10ms), the instrument is safe and reliable.
5. Safe and reliable: The controller is connected to the high-voltage generator at low voltage, with imported photoelectric control, ensuring safe and reliable use.
6. Adopting a high and low voltage closed-loop negative feedback control circuit, the output has no capacitance rise effect.
7. Fully equipped: capacitive touch screen, LCD Chinese character display, automatic storage, and automatic printing. In addition, with a U port and upper computer software, experimental data can be uploaded online, making the instrument more complete.
8. The high-voltage output protection resistor is designed within the boosting body, so there is no need to connect another protection resistor outside. 9. Large testing range: 0.1Hz, 0.05Hz, and 0.02Hz multiple frequency selection, with a large testing range.
10. Small size, light weight, convenient transportation, and very conducive to outdoor work.
11. Switching between Chinese and English backend (other languages can also be customized), exporting to multiple countries.
12. Widely used for AC withstand voltage testing of large capacity equipment such as generators, cables, and power containers
