IMD with UL 2231 approval – especially for DC charging stations
Electrical safety must be guaranteed during the charging process. For this purpose, an unearthed DC power supply system (IT system) with insulation monitoring is set up and monitored with an insulation monitoring device (IMD). Dold has developed a smart insulation monitoring solution for DC charging stations that also fulfils the requirements of UL 2231. The insulation monitor RN 5893 from the VARIMETER IMD family monitors the charging process from the charging station to the vehicle in combination with the coupling device RP 5898.
– Response delay < 10 s - Nominal voltage up to DC 1000 V - Manipulation protection due to sealable transparent cover
