China Cheap price Ac Charging Pile Metering Module - JSY-MK-333 Three phase embedded electric energy metering module – JIAN SI YAN Detail:

Description

Jsy-mk-333 three-phase embedded measurement module is a three-phase embedded measurement module with completely independent intellectual property rights developed by our company using microelectronic technology and special large-scale integrated circuits, using advanced technologies such as digital sampling and processing technology and SMT process. The technical performance of the detector fully meets the relevant technical requirements of 0.5s three-phase active watt hour meter in IEC 62053-21 national standard, and can directly and accurately measure the voltage, current, power, power factor, electric quantity, total amount and other electrical parameters in a three-phase AC network with a rated frequency of 50Hz or 60Hz. The metering module is equipped with 1-way RS485 communication interface (optional), 1-way TTL interface and MODBUS-RTU communication protocol, which is convenient to connect with various single-chip computers. It has the characteristics of good reliability, small size, light weight, beautiful appearance, convenient installation and so on.
