Overview
The ZLXZB series frequency modulation resonance withstand voltage test device applies the principle of series parallel resonance. By adjusting the output frequency of the frequency converter controller, the inductance L of the reactor in the circuit and the capacitance C of the test sample resonate, and the resonant voltage is the voltage applied to the test sample.
