ISOMETER® isoEV425 with coupling device AGH420 Insulation monitoring device for unearthed DC circuits (IT systems) for charging electric vehicles Product description The ISOMETER®s of the isoEV425 series monitor the insulation resistance of unearthed AC/DC main circuits (IT systems) with nominal system voltages of 3(N)AC, AC, AC/DC 0…690 V or DC 0…1000 V. The main application fields are unearthed DC charging stations (mode 4 according to IEC 61851-23) for electric vehicles (IT systems) with nominal system voltages of DC 0…1000 V. Due to a separate supply voltage, de-energised systems can...
