Product Guide
How the System Works
The VS-ZGF200-5 converts AC input power into high-frequency voltage through PWM-controlled IGBT switching technology. The high-frequency voltage is then stepped up and rectified by the multiplier tower to generate stable DC high voltage output.
The digital control system continuously monitors output voltage and current during testing. When testing zinc oxide surge arresters, the dedicated 0.75UDC1mA function allows rapid and accurate measurement of reference voltage and leakage current values.
