Multi-function electric energy meter TC55L

three-phaseDIN railRS-485

TC55L series are three phase external CT connected multifunctional energy meter to measure and analyze the most important electrical parameters, including voltage, current, four-quadrant power parameters, power factor, total harmonic, and etc. And it can also read a variety of energy parameters, involving bidirectional active and reactive energy, four-quadrant energy, and so on. The series realizes the measurement and analysis of power parameters in various power grid environments, such as 1P2W, 3P3W and 3P4W. The TC55L series have both LoRaWAN and RS485 communication interface with highest baudrate 38400bps, supporting Modbus or DLT645 protocol for remote reading. At the same time, the large-screen LCD and touch buttons help users to view and set various measurement parameters on site. Password protection function is added to greatly improve the data security. 1A/5A, or mV/mA Current Transformer/Rogowski Coil Input Measurements: V,A,W,Var,kWh,kVarh,PF, THD...
