MOQ: Not Specified
 
Products Introduction

40KV vlf high voltage generator of this product fully complies with the standards of the electric power industry. Mechanical methods are widely used to modulate and demodulate ultra-low frequency signals, but there is no standard sine wave, some errors in high-voltage part measurement and spark discharge. The product can overcome the above shortcomings.

How to choose the suitable products for test

Please make sure that the capacitance of test products is below the instrument rated capacitance. The waveform will be influence if the capacitance of test products is too small and the instrument can not normally output when it below 0.05µF. 0.05µF capacitor in parallel to auxiliary output.
