The ME431 DIN-Rail three-phase multifunction power meter can be externally connected to an open-ended Rogowski coil or a voltage-type CT to realise testing without dismantling the wiring, which simplifies the testing process and effectively saves construction costs.The ME431 supports simultaneous access to a maximum of four three-phase circuits, which requires that the voltage signals are kept the same while the current signals are accessed to the meter through the RJ45 connector. The meter is compatible with three-phase three-wire and three-phase four-wire systems; it is capable of measuring a wide range of electrical parameters such as current, voltage, power factor, harmonics, power, electrical energy, etc., in three-phase grids A, B and C. The ME431 is also available in zero sequence detection and temperature detection versions.
The ME431 is equipped with RS485 and Ethernet interfaces as standard, supports Modbus-RTU and Modbus-TCP protocols, and is compatible with a wide range of configuration systems, enabling real-time transmission of collected electrical parameters to the system data centre.
