China Cheap price Current Meter Head - JSY-MK-339 Three phase voltage and current collector – JIAN SI YAN Detail:

Description

Jsy-mk-339 three-phase voltage and current collector is a three-phase watt hour meter 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 tester fully meets the relevant technical requirements of class 1 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 the three-phase AC network with the rated frequency of 50Hz or 60Hz. The detector has a built-in 4G communication module, a RS485 communication interface, a dot matrix LCD display, and MODBUS-RTU communication protocol, which is convenient to connect with various AMR systems. It has the characteristics of good reliability, small size, light weight, beautiful appearance, convenient installation and so on.

Features
