VLF series 0.1Hz ultra-low frequency insulation withstand voltage generator combines the advanced technology of modern digital frequency conversion, adopts microcomputer control, step-up, step-down, measurement, protection fully automatic, and can perform manual intervention in the automatic promotion process. Because of the full electronic, the volume small weight light, large screen liquid crystal display, clear and intuitive, and can display the output waveform, print output test report.
It consists of host control machine,compensation capacitor, boosting transformer,carry case.
1.Real and accuracy test results of current, voltage, waveform directly get from high voltage lateral sampling.
2.Over-voltage protection: device stop running when output over setting max voltage, action time <20ms.
3.Over-current protection:double protection for high and low voltage, stop running accurately protect high voltage according to set parameter, stop running when low voltage current over rated current, time <20ms.
4.No need to connect extra protection reactor because of high voltage protection reactor inside booster.
5.Due to use high and low voltage closed loop control circuit, output without capacitive rise effect.
