Overview

Variable frequency resonant series device - The design concept adopted in the specifications, high-quality IGBT and drive circuit make the output waveform distortion small, the frequency output stability good, and it has good IGBT, overcurrent, overvoltage (protection values can be manually adjusted according to needs) and discharge protection functions, which can protect the safety of equipment and personnel; When the test sample discharges or breaks down, due to the destruction of resonance conditions, the short-circuit current is small, only 1/Q of the test current of the test sample, avoiding damage to the test sample caused by breakdown.
