This series of ultra low frequency high voltage generator is the core product developed by itself, using 7 inch touch screen, ARM7 single chip microcomputer, high-speed AD acquisition circuit, and equipped with background management software. High cost performance, especially suitable for electrical equipment with large insulation equivalent capacitance (such as power cables, power capacitors, large and medium-sized generators and motors, etc.) voltage test

1, MCU control, 7 inch large screen touch operation, photoelectric data transmission, digital frequency conversion, automatic test
2, strong power, high efficiency, strong carrying capacity, and simple wiring, convenient operation, not easy to make mistakes, especially the overall weight is greatly reduced, carrying and transportation more convenient.
3, Rated voltage: 30KV, 40KV, 50KV, 60KV, 80KV, 90KV, etc., current, voltage, waveform data are directly sampled from the high voltage side, so the data is accurate.
4, comprehensive protection: multiple protection (overvoltage protection, high and low voltage sidecurrent protection), rapid action (action time ≤10ms), the instrument is safe and reliable.
5, safe and reliable: controller and high voltage generator low voltage connection, safe and reliable use.
6, the use of high and low voltage closed loop negative feedback control circuit, output without capacity rise effect.
7, complete configuration: capacitive touch screen, LCD Chinese character display, automatic storage, automatic printing. In addition, U port and upper computer software can upload test data online, which makes the instrument more perfect.
8, the high voltage output protection resistance is designed in the booster body, so there is no need to connect another protection resistance outside.
9, large test range: 0.1Hz, 0.05Hz and 0.02Hz multi-frequency selection, large test range.
10, small size, light weight, convenient transportation, very conducive to outdoor operations.
