FAQs
Q: What are the requirements for the input power supply? Is 380V the only option?
A: The fourth-generation unit is not limited by the input power supply; both 220V and 380V can be used as the operating power source for the equipment.
Q: Does the system support remote control?
A: When testing non-capacitive specimens, the capacitive voltage divider also functions as a resonant capacitor.
Q: What is the measurement accuracy and waveform quality?
A: The system has a measurement accuracy of Class 1.5, with a voltage measurement accuracy of 0.5% for the variable-frequency power supply; the output voltage waveform distortion rate is ≤1%.
