SEM34-D100

SEM34-D100 is a rail mounted three-phase multifunctional MID energy meter that supports RS485 Modbus/DLT645 communication, and is a high-end product in the SEM series. This product perfectly embodies the characteristics of "small size, large functionality". This series can be used for various power grids such as three-phase 4-wire, three-phase 3-wire, single-phase 2-wire, two-phase 3-wire, 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. Forward and reverse electricity bidirectional metering, with 5 selectable total electricity calculation modes. Has 2 pulse outputs, with 1 pulse output adjustable; 1 RS485 communication channel (optional communication protocol: Modbus RTU; RS485 communication speed up to 38400bps (customizable higher speed); It has good electromagnetic compatibility, with an accuracy of up to 0.5 level, in compliance with international standards GB/T17215, GB/T15284, GB/T17883, and power industry standards DL/T614, IEC62053-21, EN50470-3:2022, and has passed the MID (European Measurement Instrument Directive) B+D certification. Widely used in fields such as solar photovoltaics and charging metering at charging stations.
