Intelligent DC high voltage generator, the main function of this product is to output negative DC high voltage, with good voltage stability and high accuracy. It is an essential product for preventive testing and DC insulation withstand voltage testing. The product is widely used in preventive testing and research institutes of power generation and supply departments, transmission and transformation engineering companies, and large factories and mines.

1. The instrument is controlled by a microcontroller, with a 192 * 64 dot matrix Chinese menu, yellow green backlight, and clear display under sunlight.

2. The software can automatically complete the test by setting the test voltage, protection voltage, and test duration.

3. It has functions such as overvoltage protection, overcurrent protection, disconnection protection, non-zero start, grounding detection, and overload protection.

4. It has clock calendar display and environmental temperature and humidity detection functions.

5. It can store 200 sets of test data, which can be directly printed or exported to a USB flash drive. The data is exported in TXT format in table format and can be printed directly on a computer.

6. RS232 communication interface with high voltage isolation, capable of remote control.

7. The anti surge ammeter and the host have wireless communication function, and the ammeter data can be directly displayed on the host.

8. It has automatic testing, 10 step testing, manual testing, and automatic testing functions for zinc oxide lightning arresters.

9. Unique capacitive test sample automatic boost mode to avoid overcurrent and interruption of testing.

10. Using a digital potentiometer with 7 selectable step voltages:

60-160kV equipment (0.05kV, 0.1kV, 0.2kV, 0.5kV, 1.0kV, 2.0kV, 5.0kV)
