Product introduction

VLF Ultra-low Frequency High Voltage Generator combines the modern digital frequency advanced technology, uses computer control, boost, buck and measurement, automatical full protection, and in the process can automatically boost can carry a manual intervention in the process of automatical boosting. Since all with electronic, is small and light, large-screen LCD displayed, clear and intuitive, printer out testing report. The Design indicators is in full compliance "special test equipment electrical equipment General technical conditions, Part 4: ultra-low frequency high voltage generator general technical conditions" power industry standard, easy to use. Nowadays home and abroad adopted mechanical approach to produce VLF modulation and demodulation to generate signal, so there is no standard sine waveform, and measurement error is large, high-voltage part with a spark discharge, heavy equipment, and the two and four-quadrants of sine wave, need large power high voltage resistance to discharge and sharp, the total total power consumption is very large. The VLF Ultra-low Frequency High Voltage Generator can overcome these shortcomings.

Alternative name

VLF high voltage generator, VLF high voltage generator, programmable VLF frequency high voltage generator, VLF frequency AC high voltage testing equipment, VLF frequency withstand testing equipment, VLF frequency generator.
