1. The required power supply capacity is greatly reduced, and the power required for the test is only 1/Q of the test capacity.
2. Small size, light weight, generally 1/3-1/5 of the ordinary test device;
3. The resonant power supply is a resonant filter circuit, which can improve the waveform distortion of output voltage, obtain good sinusoidal waveform, and effectively prevent the wrong breakdown of the sample by harmonic peak value.
4. Variable-frequency power supply has strong protection function and good stability. It has automatic (automatic tuning, automatic boosting), full manual (manual tuning, manual boosting) and semi-automatic (automatic tuning, manual boosting and manual tuning, automatic boosting) working modes, which can be switched over and used arbitrarily and operated conveniently. 220V or 380V single-phase power supply is used to facilitate on-site power access.
5. Flexible configuration, strong expansion function. The resonant reactor adopts multi-mode, building block combination, can be series and parallel, which meets the test requirements of a variety of samples and is more convenient for field use.
6. Large screen touch LED LCD color screen and external mouse directly complete the setting of various parameters. The test results can be saved, printed, uploaded, retrieved and so on.
7.The frequency regulation of ZCVF-A series frequency conversion series resonant AC withstand voltage device can be divided into coarse tuning and fine tuning, and the test resonant point can be automatically found to ensure that the resonant frequency does not drift during the whole test process; the required power supply capacity is small, the power required for the test is only 1/Q of the test capacity; the volume is small, the weight is light, and the resonant power supply is 1/3-1/5 of the ordinary test device; the resonant power supply is resonant type. The filter circuit can improve the waveform distortion of the output voltage, obtain good sinusoidal waveform, effectively prevent the wrong breakdown of the sample by harmonic peak value; has a variety of working modes, using 220V or 380V single-phase power supply to facilitate on-site power supply; multi-mode, building block combination, can be operated in series and parallel, easy to use in the field.
