30KV,50KV,80KV,90KV Ultra Low Frequency VLF Hipot Tester,high Voltage Generator Withstand Tester

30KV,50KV,80KV,90KV Ultra Low Frequency VLF Hipot Tester,high voltage generator withstand tester Product Description BVLF (Very Low Frequency) Testers are suitable for testing power cables, transformers, switchgear, rotating machinery and other electrical apparatus. The product combines modern advanced digital variable frequency technology and micro computer control together, therefore, it can realize the full automatic voltage boost, stepdown, measurement and protection as well as the manual intervention in the process of automatic voltage boost. The full electronic design ensures the small size and light weight. The big LCD screen ensures the clear and visual display, and can display the output sinusoidal wave form. The printer outputs test reports. In addition, the product has features as follows: Features Large touch screen：It adopts 7-inch touch screen and the latest ARM7 microcontroller. Advanced technology：Using digital frequency conversion technology, microcomputer control, step-up, step-down, measurement, protection and other testing processes are fully automated. Easy to operate：The wiring is simple and fool-proof operation. Comprehensive protection: Multiple protections (overvoltage protection, high and low voltage side overcurrent protection), rapidaction (action time ≤ 10ms), the instrument is safe and reliable. Safe and reliable：The controller and the high-voltage generator are connected with low voltage, photoelectric control, safe and reliable to use. High and low voltage closed loop circuit：High and low voltage closed-loop negative feedback control circuit is adopted, and the output has no capacity increase effect. Complete configuration：Capacitive touch screen, LCD Chinese character display, automatic storage, automatic printing. Large test range：0.1Hz,0.05Hz and 0.02Hz Multiple frequency selection, large test range. Small size and light weight：Very conducive to outdoor operations. Chinese-English switching function：Chinese-English switching, using imported high-voltage electronic switch to switch polarity. High-speed AD acquisition circuit, and equipped with USB background management software. Longer life and lower failure rate.
