ISOMETER® isoGEN423
- Insulation monitoring device for mobile generators
- Protective isolation with insulation monitoring and shutdown
- Two response values with settings between 5 and 200 kΩ (Factory settings 46 kΩ and 23 kΩ)
- Communications interface supporting Modbus RTU, IsoData, and BMS
- Overvoltage and undervoltage protection
The isoGEN423 monitors the insulation resistance of ungrounded AC, AC/DC and DC systems with nominal system voltages of 0…400 V. The monitored system can be single-phase AC, 3- or 4-wire AC, AC/DC mixed-phase, or DC.
Automatically adapts to the maximum permissible system-leakage capacitance of 5 μF. DC components existing in AC systems do not influence the operating characteristics, when a minimum load current of DC 10 mA flows. Using a separate supply voltage allows de-energized systems to be monitored.
