Product Introduction

The SYM series is a new generation of intelligent power meter developed by Henan Senyuan Electric Co., Ltd. It has multiple functions, including programming, automated measurement, LCD display, energy accumulation, harmonic measurement, event recording, binary inputs and outputs, and digital communication. The product adopts advanced microprocessors and digital signal processing technology, incorporating digitization, automatization and web-based service. Due to its superior performance, high accuracy, nice appearance, and strong electromagnetic compatibility, the SYM power meter can completely replace the traditional analog and digital instruments, and realize remote monitoring and data collection as the terminal component of electric power monitoring system. In addition, the SYM series intelligent power meter has flexible I/O function, which fully meets the application requirements of distributed RTU and realizes integrated remote signal, telemetry, remote regulation and measurement. It can be used in switchgear, power distribution system, panel control, energy management system, building control system, power station monitoring system, process control system, power distribution box and so on.


Product Features

1. Basic electrical measurement: three-phase voltage, current, active power, reactive power, power factor, frequency, energy in 4 quadrants;

2. Power metering and monitoring: real-time active and reactive power meter reading, two directions, absolute value and net value; time sharing power, cumulative time sharing active power of last month and this month; three-phase two-direction active and reactive power;

3. Power quality monitoring: unbalance of three-phase voltage and current, harmonic distortion rate of voltage and current; 2~31 harmonic ratio;

4. System integration and communication: real-time clock; one-way RS485 communication; analog output AO; 0n-off input DI; relay output DO; DI deflection sequence SOE record.
