The ME231 is a DIN-Rail three-phase multifunctional smart meter that supports externally connected with open type Rogowski coil or voltage type CT, it can realize none dismantling wire test, simplify test steps, save construction cost, and is more convenient for engineering test as well as the inspection and maintenance of distribution system.

The ME231 support systems of single-phase and three-phase. It can measure multiple electrical parameters such as current, voltage, power factor, harmonics, power, energy and other electrical parameters of L1,L2,L3.The standard RS485 communication interface can be compatible with various configuration systems through the standard MODBUS-RTU protocol.
