ISOMETER® isoPV425 con AGH420
- Insulation monitoring device for AC and DC IT systems
- Application photovoltaic systems up to AC 690 V/DC 1000 V
- Automatic adaptation to the system leakage capacitance up to 1000 μF
- Measurement of the nominal system voltage (RMS) with undervoltage and overvoltage detection
The ISOMETER® of the isoPV425 series monitors the insulation resistance of unearthed AC/DC main circuits (IT systems) with nominal voltages of 3(N)AC, AC, AC/DC 0…690 V or DC 0…1000 V.
DC components existing in AC/DC systems do not influence the operating characteristics. A separate supply voltage allows deenergised systems to be monitored as well. The maximum permissible system leakage capacitance is 1000 µF.
