Product Description

RS485 Modbus Three Phase AC Power Meter Voltage Current Power Energy Acquisition Module

Introduction

JSY-MK-323 three-phase mutual inductance power quality detector is our company adopts microelectronics technology and dedicated large- scale integrated circuits, the application of digital sampling processing technology and advanced technology such as SMT technology research and development with completely independent intellectual property rights of the three-phase power quality detector. The detector technical performance in full compliance with the national standard in IEC 62053-21 grade 1 three-phase active energy meter related technical requirements, can directly and accurately measure the rated frequency of 50HZ or 60HZ three-phase AC power grid voltage, current, power, power factor, electricity and total electrical parameters. The detector built-in 1 channel RS485 communication interface, MODBUS-RTU communication protocol to facilitate and a variety of AMR system connection, with reliability,
small size, light weight, beautiful appearance, easy installation and other characteristics.

JSY-MK-323 three-phase mutual inductance power quality detector can be widely used in energy-saving transformation, electric power, communications, railways, transportation, Environmental protection, petrochemical, steel and other industries, used to monitor the current and power consumption of AC equipment.

Functional features

• Collect three-phase AC electrical parameters, including voltage, current, power, electric energy and other electrical parameters, complete information;

• Using special measurement chip, effective value measurement method, high measurement accuracy;
  

• With 1 channel RS-485 communication interface;
  

• The communication protocol adopts standard Modbus-RTU, which has good compatibility and is convenient for programming;
  

• RS-485 communication interface with ESD protection circuit;
  

• Wide operating voltage AC80 ~ 240V;
  

• Using industrial-grade chips, built-in watchdog, and has a sound anti-lightning anti-interference measure to ensure reliability;
  

• High isolation voltage, withstand voltage up to AC: 2000V;
  

• It can be equipped with different specifications of single-turn core transformer or open-close transformer, convenient and easy to use;
  (Note: Open-close current transformers are mainly used in industrial mid-city networks, power transmission systems, rural project transformation, Easy to install, no need to disassemble a bus, can also be live operation, and does not affect the customer's normal electricity, for the user to transform. The project saves a lot of manpower, material and financial resources and improves the efficiency of transformation. This series of open-close current transformer can be used with relay. The protection, measurement and current meter metering devices are used together.)
