ISOMETER® isoEV425 con AGH420

ISOMETER® isoEV425 con AGH420

The ISOMETER® of the isoEV425* series monitor the insulation resistance of unearthed DC-charging stations for electric vehicles (IT systems) DC 0…1100 V DC from the charging station to the motor (AC 0…793 V).

Due to a separate supply voltage de-energised systems can also be monitored.
