ZGF-120kV/2mA high-frequency DC high-voltage generator features　　



1. Small size, light weight, more beautiful, more reliable, easy to operate, complete functions, convenient for field use, it is an ideal reliable product in the new century. 

2. Adopting advanced technology and manufacturing processes, it takes the lead in applying new PWM high-frequency pulse width modulation technology and pulse train logic array modulation, using high-power IGBT devices, and utilizing high-frequency technology to increase frequency up to 100kHz, thereby making the output high voltage more stable and the ripple coefficient smaller. 

3. High-frequency DC high-voltage generator has high precision and accurate measurement. Both voltage and current are digitally displayed, with voltage resolution of 0.1kV and current resolution of 0.1uA. The voltmeter on the control box directly displays the voltage value applied to the load test object, eliminating the need for an external voltage divider and simplifying wiring. The instrument has the ability to measure leakage current at both high and low voltage ends. The high-voltage end uses a circular digital meter display, which is resistant to discharge impact and has good anti-interference performance, suitable for on-site use. 

4. High voltage regulation stability, smooth voltage adjustment across the full range. The output voltage adjustment uses a single imported multi-turn potentiometer, ensuring smooth boosting process and high adjustment precision, with coarse and fine adjustment functions designed. Voltage regulation is better than 0.1%, voltage and current measurement errors are less than 1.0%, and ripple factor is better than 0.5%. 

5. Negative polarity output, zero-start, continuously adjustable, with various protection functions such as overvoltage, overcurrent, return-to-zero, grounding protection, and unique disconnection protection. The automatic protection circuit is powerful, with complete and reliable protection, ensuring safe operation. All technical indicators are superior to industry standards and similar products. 

6. High-frequency DC high-voltage generator has added a high-precision 75% VDC-1mA function, bringing great convenience to zinc oxide arrester measurements. With a simple press, no calculation is needed. The control box has a 75% voltage function key. When doing zinc oxide arrester tests, when the current rises to 1000uA, press the 0.75 button. At this time, the values displayed on the voltmeter and ammeter are the 75% data. After completion, immediately return the boosting knob to zero, and also return the fine voltage adjustment knob to zero, then immediately press the green button to cut off the high voltage and turn off the power switch. Then proceed with other tests. 

7. Convenient overvoltage setting function, using a digital dial switch, which can display the set voltage value intuitively, making your operation more casual, with the displayed value in kV. 

8. The voltage doubling cylinder has a sectional structure, flexible and convenient for field use, one machine with multiple uses, economical and practical
