SEM34-T5

SEM34-T5 is a CT type rail three-phase energy meter. This meter can be applied to various power grids such as 1P2W, 3P3W, 3P4W, etc. It can measure various important power parameters, such as active power, reactive power, voltage, current, active power, reactive power, apparent power, frequency, power factor, demand, phase separation power, total harmonic content, etc. The product also has an RS485 Modbus communication port, which is compatible with various configuration systems, allowing real-time transmission of data collected by the front-end to the system data center, making it easy for users to achieve remote communication in various situations and perfect for application in AMR/SCADA systems. It is an ideal instrument for energy monitoring and management systems and automatic meter reading systems. The product adopts a modular design, which has the advantages of multifunctionality, high stability, high precision, long life, small size, easy installation, easy networking, and good electromagnetic compatibility. Compliant with national standards GB/T17215, GB/T15284, GB/T17883, as well as power industry standards DL/T614, IEC62053-21, EN50470-1/3, and certified with MID (European Metrology Directive) B+D and UL 61010.
