SKIM200 is an insulation monitoring device for IT system control circuits below AC, and AC/DC 230V. SKIM200 can only perform insulation monitoring independently and cannot be combined with the insulation fault location.
SKIM200 Insulation monitor features:
1. Applicable to IT systems control circuits below AC/DC 230V;
2. Internal/external testing/reset buttons;
3. Automatic and manual reset functions;
4. Multi type, wide range control power input;
5. Humanized and easy to operate interface, which can display various parameters and system leakage capacitance;
6. DIN rail installation method;
7. LCD screen display with backlight;
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).
