Product introduction

NAVLF Ultra-low Frequency High Voltage Generator combines the modern digital frequency advanced technology, uses computer control, boost, buck and measurement, automatically full protection, and in the process can automatically boost can carry a manual intervention in the process of automatically 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 NAVLF 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 NAVLF Ultra-low Frequency High Voltage Generator can overcome these shortcomings.

Also called name
