One electrical safety device. Two charging standards. Endless benefits.

Insulation monitors for DC fast chargers that measure isolation between the high-voltage system and ground (frame). The ISOMETER® isoCHA425HV in combination with the AGH420-1/AGH421-1 coupling device monitors the insulation resistance for DC fast charging stations according to the CHAdeMO standard or according to the Combined Charging System (CCS) for nominal system voltage ranges between DC 0 V and 1000 V.

  • Maintains UL compliance
  • Ensures electrical safety
  • Guarantees uptime and reliability
  • Avoids electrical hazards
  • Provides visibility into the charger's electrical integrity
