DC6 Residual Direct Current - Monitoring Device
    Publish time 2021-05-08 21:58    
Residual current monitor of DC fault current above 6 mA compliant with IEC 62955 standard as RDC-MD
The DC6 RDC-MD - a residual current monitor of DC fault current above 6 mA for Mode-3 EV charging - facilities AC EV chargers to meet the residual current protection request defined in IEC 61851-1 & IEC 60364-7-72, when the device is used together with Type-A RCD. It is globally the first Residual Direct Current – Monitoring Devices certified by TÜV Rheinland. 

The DC6 RDC-MD contains two separated modules with detection module (DC6-iRCS-32 or BRCS-01) and monitoring module (DC6-C1/C2). Residual direct current detection of the charging station takes place via the externally connected detection module. When the residual direct current in the charging station is more than the defined threshold value, the detection module will send the digital trip signal to the monitoring module to switch the relay and active the alarm indication. 

mer Benefits
  • Safety upgrading: Test can be conducted before every charging circle with interface to charging controller
  • Easy configuration: Fast response time facilitates the wide selection of main-circuit switching devices
  • Cost-effective: Two-channel monitoring design perfectly fits for AC 2 * 22kW public or commercial charging
  • Flexible application: EV Charger manufacturers can configure a IEC 62955 RDC-MD with our detection module and own charging controller
