Carlo Gavazzi DCM1 DC Energy Meters with Ethernet

Carlo Gavazzi DCM1 DC Energy Meters with Ethernet are direct-connection devices for DC systems up to 1000V and current up to 600A. These meters feature two components: a transducer for voltage and current connection and a display unit with both Modbus RTU and Modbus TCP communication ports. The cable that links the two parts is included and connected to the transducer for quick and easy installation. The DCM1 energy meters are installed on the DC side and are compatible with most DC chargers. The meters include a cable loss compensation function so only energy provided to the vehicle battery is considered, and the losses due to cable resistance are removed. Data authenticity is guaranteed via signed data transmission to the controller, and the display updates automatically to show relevant charging session information. Carlo Gavazzi DCM1 DC Energy Meters with Ethernet are designed to be tamper-proof and support horizontal or vertical mounting.
