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 interface
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 test 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.
