SKIM1000EV is an insulation monitoring device（also known as insulation monitoring relay）for IT system main circuits below DC1000V, which is specifically designed for DC charging piles, charging station, battery energy storage, and Solar power, which is special for DC power grid, SKIM1000EV not only demonstrates the technical advantages of low-frequency injection method, but also shows superior performance in cost control.
Feartures:
1. Built in/external testing/reset buttons
2. Automatic and manual reset functions
3. Multi type, wide range control power input
4. Humanized and easy to operate interface, which can display various parameters and system leakage capacitance
5. DIN rail installation method
6. LCD screen display with backlight
7. Communication enables reading of positive to ground, negative to ground voltage and insulation resistance values
8. Measure and display the insulation resistance of ungrounded systems
9. Measurement and display of leakage capacitance (C)
10. Communication via Modbus RS-485
11. Adjustable response delay
12. Two independent alarm relays (each relay has a switching contact)
13. N/O or N/C operation, (Optional)
