Overvoltage protector tester successfully detects 1mA DC voltage

Performance characteristics:

1. The instrument uses waveform detection and Fourier transform to constantly monitor the discharge current. When the discharge current is detected, the high voltage is immediately recorded and the high voltage power supply is cut off within 0.2 seconds. The test results have high accuracy, making it easy to achieve automated measurement.

2. The instrument adopts a large screen LCD display, and the testing process is both intuitive and easy to operate through Chinese character menu prompts.

3. The instrument is easy to operate, and the measurement of data is automatically completed under the control of a microprocessor. No need for manual intervention

4. Integrated model with built-in high-voltage power supply for easy on-site testing and reducing on-site wiring

5. High voltage protection: In case of short circuit, breakdown or high voltage current fluctuation of the test sample, the output can be cut off at high speed in the form of a short circuit.

6. Low voltage protection: In case of accidental connection to 380V, power fluctuation or sudden power outage, the protection will be activated without causing overvoltage.

7. Anti misoperation: two-stage power switch; Real time monitoring of voltage and current; The high/low voltage of the wiring terminal is clearly defined; Slow boost, can quickly reduce pressure, sound alarm. 9. Seismic performance: The instrument adopts seismic design, which can withstand strong long-distance transportation vibrations and bumps without damage.
