Product Description


1. Cortex-M3 STM32 chip as the Master chip, high integration high anti-interference ability, high running speed, low power dissipation

2.Menu operation with humanization design

3. All relative parameters can be set via menu, alarms all through sound and light output or relative dry contact output

4. Can accurately measure DC voltage, module state, insulation, can discriminate bus grounding and branch grounding, can display grounding resistance, and detect grounding fault in two or more branches.

5. Can test and monitor all branches grounding

6. Can make circle test of all the branches, or select one branch to test

7. Store and display the latest 5 times bus insulation warning records

8. Can test two sections bus ripple voltage and ripple coefficient

9. No consistence request or direction request to CT polarity

10. RS485 interface technology for signal sampling make the effective transmission distance reaches 1000 meters

11. With RS232, RS485 communication interface for connecting with external equipment

12. With 100M Ethernet infterface

13. Fast branch testing

14. Can set AC sneaking in alarm threshold ( AC RMS)

15. Using real-time tracking information zero processing technology to realize AC signal sneaking into DC fault testing and alarm

16. Color screen with LCD self-protection function

17. With simple multi-machine connection function for complicated multilevel DC system

18. Can real time measure power ripple, voltage, ripple coefficient in all ranges. It also can effectively record the AC content in DC power source.
