The main functions and technical features of our company's high-voltage withstand voltage test device series are:

1. The equipment has protection functions such as overvoltage, overcurrent, zero start, and system detuning (flashover).

2. The weight and volume of the equipment are 1/10-1/30 of that of a regular testing device. The power required for the experiment is only 1/Q of the test capacity.

3. The device has three working modes: fully automatic mode, manual mode, and automatic tuning manual boost mode

4. Store and print data, with numerical numbers for easy identification and retrieval by users.

5. The starting point of the frequency during automatic frequency scanning of the device can be set arbitrarily within the specified range.

6. DSP platform technology can add or remove functions and upgrade according to user needs, making the human-machine exchange interface more user-friendly.

7. Improve the waveform of the output voltage.

8. Prevent large short-circuit currents from burning the fault point.

9. There will be no overvoltage recovery.
