Empowering the next generation of electric vehicle charging infrastructure
DCES600 and DCES1500 meter designs support current levels up to 1500 A without derating over temperatures ranging from -40°C to +85°C. This ensures precise kilowatt-hour (kWh) billing throughout the charging cycle, including the low-current phase common at the end of charging.
Both models comply with international metrology standards, paving the way for approval by European regulatory authorities, including MID 2014/32/EU and the German Eichrecht. This compliance is particularly important for commercial EV fleets and megawatt-scale charging hubs, where billing accuracy and traceability are crucial.
