This series of high voltagedirect currentThe generator adopts a high-frequency voltage doubling circuit, applies PWM high-frequency pulse width modulation technology, closed-loop adjustment, and adopts voltage feedback to greatly improve voltage stability. By using high-power IGBT devices and their driving technology, and based on electromagnetic compatibility theory, adopting special shielding, isolation, and grounding measures, the high-voltage DC generator has been made portable and can withstand rated voltage discharge without damage.

Features
1. By using PWM high-frequency pulse width modulation technology, pulse train logic array modulation, high-power IGBT components, and high-frequency technology to increase the frequency up to 100kHz, the output high voltage stability is higher and the ripple factor is smaller.
2. This high-voltage direct current generator is small in size, light in weight, more aesthetically pleasing, more reliable, easy to operate, fully functional, and convenient for outdoor use.
3. High precision and accurate measurement. Voltage and current are both displayed digitally, with a voltage resolution of 0.1 kV and a current resolution of 0.1 μ A. When using the instrument, there is no need to add a high-voltage measuring instrument. The digital voltmeter on the control box can directly display the voltage value applied to the load sample. The instrument has high and low voltage ends for measuring leakage current, and the high voltage end is displayed with a circular shielded digital meter, which is not afraid of discharge shock and has good anti-interference performance, suitable for on-site use.

4. High voltage regulation stability, smooth voltage regulation across the entire range, multi turn potentiometer for output voltage regulation, smooth boosting process, high regulation accuracy, and designed with coarse and fine adjustment functions. The voltage regulation is better than 0.1%, the measurement error of voltage and current is less than 1.0%, and the pulsation coefficient is better than 0.5%.

5. Negative polarity output, zero start, continuously adjustable, with protection functions such as overvoltage, overcurrent, and return to zero. The automatic protection circuit has strong functions, complete and reliable protection, and safe operation.
6. The high-precision 75% VDC-1mA function has been added, making it very convenient to conduct tests on zinc oxide lightning arresters. A gentle press does not require calculation. There is a 75% voltage function key on the control box of this instrument. During the zinc oxide test of the lightning arrester, when the current rises to 1000 μ A, open the 0.75 button. At this time, the values displayed on the voltmeter and ammeter are 75% of the data. After completion, immediately return the voltage boosting knob to the zero position, and at the same time, adjust the voltage knob to the zero position. Press the green button immediately to cut off the high voltage and turn off the power switch. Conduct other experiments.

7. The convenient overvoltage setting function adopts a digital dial switch, which can intuitively display the set voltage value, making your operation more flexible. The displayed value is in kV.
8. The pressure doubling cylinder can be used in sections according to needs, which is flexible and convenient. It can be used for multiple purposes and is economical.
9. There are three concealed support feet at the bottom, which increase the stability of the pressure doubling cylinder.
