DCBM 100 - Benefits & Features

DCBM 100 dc meter for wallbox



Smart and compact, the Direct Current Billing Meter (DCBM) gives electric vehicle chargers providers the ability to provide kWh-based charging experience, using display to show real time measurements, energy, and handle charging sessions with legal data.

An excellent solution for DC destination charging applications in the range of 30kW, the DCBM uses industry standard data protocols. The results are secured communication, authentic billing, easy connectivity to Cloud services and a faster certification process in compliance with metrology regulations.
