Three Phase Three Wire DIN Rail Meter function
Active energy measurement:Focusing on the accurate measurement of active energy in the circuit and providing users with accurate power consumption data is one of the core functions of power metering.
Single energy direction :Only the power flowing from the power grid to the power consumption equipment is measured, which is suitable for power consumption scenarios with fixed energy flow direction.
1TE width:"1TE" here usually refers to the installation width unit occupied by the device on the DIN rail, which can be easily installed in a limited installation space.
Modbus interface:Equipped with a standard Modbus communication interface, it can realize data transmission and communication with other smart devices or systems.
Applicable to AC electric vehicle charging stations and any itemized billing applications:It can accurately measure the power consumption during the charging process of electric vehicles.
MID certificate:Possessing a MID (Measuring Instruments Directive) certificate indicates that the meter complies with the relevant EU directive requirements on measuring instruments.
