PEC-EM3-100A-MID : Three-phase energy meter 100A with RS485 Modbus and pulse output, MID version
The PEC-EM3-100A-MID is a standard multifunctional three-phase energy meter for mounting on a DIN rail with RS485 MODBUS serial communication. This product performs measurements and analyses of various parameters, such as voltage, current, the four-quadrant power parameters, the power factor, harmonic components, etc.;
Additionally, it can also perform measurements of different types of energy, such as active energy in both directions, reactive energy, and monthly and daily statistics on electricity consumption. This product series supports various wiring systems, such as single-phase and three-phase systems, and is suitable for power monitoring of photovoltaic inverters, statistical analysis of electricity consumption from new energy sources, real-time power monitoring, and various other applications. The product is characterised by its multifunctionality, high stability, and long lifespan.
This product is equipped with an RS485 communication interface, with a maximum baud rate of 38,400 bps. It makes it easy to read data remotely and is equipped with a large LCD screen and touch-sensitive buttons, allowing various parameters to be easily viewed and set on-site. The product features password protection, which ensures the data security of the product. The extensive communication functions make it highly suitable for various control systems, SCADA systems, and energy management systems.
