KDVLF series ultra-low frequency high voltage generator integrates modern digital frequency conversion high technology, adopts microcomputer control, automatic voltage boost, buck, measurement and protection, and can carry out manual intervention in the automatic voltage boost process. Because of electronic, so small size and light weight, large screen LCD display, clear and intuitive, and can display output waveform, printer output test report.

1, the rated voltage is less than or equal to 50kV ultra-low frequency using a single link structure (a booster); The ultra-low frequency of more than 50kV adopts a series structure (two boosters in series), which greatly reduces the overall weight and enhances the load capacity, and the two boosters can be used separately for the ultra-low frequency of low voltage levels.
2, current, voltage, waveform data are directly sampled from the high voltage side, so the data is accurate.
3, overvoltage protection function, when the output exceeds the set voltage limit value, the instrument will stop protection, operation time is less than 20ms.
4, with overcurrent protection function: designed for dual protection of high and low pressure, the high pressure side can be accurate shutdown protection according to the set value; When the current on the low voltage side exceeds the rated current, the shutdown protection will be carried out, and the operation time is less than 20ms.
5, the high voltage output protection resistance is designed in the booster body, so there is no need to connect another protection resistance outside.
6, due to the use of high and low voltage closed loop negative feedback control circuit, so the output has no capacity rise effect.

1, output rated voltage: 0 ~ 50kV(applicable to 10kV and below cable 0 ~ 12km voltage test, generator voltage, etc.)
2, output frequency: 0.1Hz, 0.05Hz, 0.02Hz
3, output frequency with load capacity: 0.1Hz maximum 1.1µF /0.05Hz maximum 2.2µF
