TC45M 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, 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, including 1P2W and 3P4W.
The TC45M series have RS485 communication interface with highest baudrate 38400bps, supporting Modbus or DLT645 protocol for remote reading.
Password protection function is added to greatly improve the data security.
