RDVLF-Z40Y VLF HV Withstand Voltage Tester
Withstand voltage testing includes AC and DC methods. AC withstand testing mainly covers power frequency, variable frequency, and 0.1Hz very-low-frequency (VLF) technologies. As an IEC-recommended advanced testing method, 0.1Hz VLF technology offers excellent performance for high-voltage insulation testing. The RDVLF-Z40Y features auto-variable frequency true sine wave output (0.1–0.01Hz), real-time voltage and current waveform display, optical isolation, closed-loop feedback control, and overvoltage/overcurrent protection. With high-voltage side direct sampling, data storage, built-in printer, and portable design, it is suitable for on-site AC withstand voltage testing.
