High Precision VLF Tan Delta Tester, AC DC Withstand Voltage Test Device for Cable

XHDP series VLF high voltage generators integrate digital frequency conversion and intelligent microcomputer control systems. The whole testing process of voltage adjustment, data monitoring and safety protection is fully automatic. Its portable structure saves space, and the large LCD monitor delivers clear visual information. Meanwhile, it supports real-time output waveform display and test report printing for convenient data recording.
