SEM12-D100

SEM12-D100 is a 100A single-phase multifunctional energy meter with RS485 communication and 2 module sizes. This device measures power parameters such as active energy, reactive energy, current, voltage, power, power factor, frequency, and demand. The bidirectional metering function makes it an ideal choice for solar photovoltaic measurement. The product has two built-in pulse output ports and one RS485 communication port, which can achieve Modbus RTU communication or DLT645 communication, making it an ideal choice for energy monitoring management and automatic meter reading systems. Compliant with electrical standards DL/T645, IEC62053-21, EN50470-1/3, and certified by MID (European Appliance Directive).
