1.wall-moounted installation,3-phase electric quantity measuring 2.128*64LCD display 3.3-month data memonth

Products summary

1. Distribution intelligent monitoring terminal has all-around 3-phase power           

Measurement,128*64LCD display ,harmonic analysis, over limit control ,the quantity of switch output /input, moving reactive compensation ,electrical energy computation ,event record ,communication as one.

2.original appearance design, it has two ways terminal that choi hanging and embedded .It installation on panel or cabinet. When you think about the installation methods , you should according to the routing principle of easy to installation ,look and collection ,in favor of signal and power.

3.be the same with public variable area ,industrial enterprises ,JP cabinet ,phasetransition , digital auto motor distribution and intelligent reactive compensation controller .

4.The software arithmetic of developed AC sample , precise and reliable combing the hardware circuit, embedded with lead can turn type panels, apply to constantly up granding electric field ,reliable emc design and make to a kind of distribution intelligent monitoring terminal convenience.

5.Distribution intelligent monitoring terminal support RS-232/485gorge line one and RS-485gorge line two .The gorge line two is data resent gorge line(just used in embedded) and it main support more function resent data of electric electrical degree .

The communication method of gorge line one support UTP ,Coaxial Cable ,Data Radio and GPRS ,otherwise it also exploit light MODBUS and optical fiber to communicate .It finished a kind of the monitor function of the distribution terminal ways.
