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);
it is easy to realize the intelligentization of the switchgear in the original switchgear equipment, and it can easily cooperate with mainstream circuit breakers such as abb, schneider and siemens;
support modbus rtu and profibus protocol, standard disclosure agreement, provide corresponding technical support;
supports up to 4 channels of 4~20ma output modules, the output power is optional, and the range is adjustable.
