ISOMETER® isoEV425 with AGH420
- Insulation monitoring device for AC 690 V and DC 1000 V IT systems
- Monitoring of DC charging stations for electric and hybrid vehicles
- Settings in accordance with IEC 61851-23
- Parameter settings by the customer not required
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.
