Musktool- SKIM200 Insulation Monitoring Device for IT system control circuits
| 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). |
