Device overview:
The UNT-NMI intelligent network instrument is a network power meter designed for the power monitoring needs of various enterprises. It can measure all common power parameters such as three-phase current, three-phase voltage, power, frequency and electric energy. In addition, this device can provide complete communication networking functions, analog uploading and other functions, which is very suitable for real-time monitoring systems. After years of engineering practice, UNT-NMI integrated intelligent meters have been widely used in power, chemical, paper, metallurgy, municipal, coal and many other fields, and the operation is stable and reliable.
Device features:
? Full parameter measurement, can replace all single and three-phase electricity measurement instruments;
? can replace all traditional power transmitters;
?Multiple voltage level input (low voltage 400V direct access, PT100V access);
? Provide a standard communication interface;
The utility model has the advantages of small size, convenient wiring and installation (especially suitable for installation on a switch cabinet);
