Profile
MDM3100 is a powerful multifunction power meter that measures more than 60 parameters such as P, Q, cosΦ, F, kWh, kvarh, etc.
The standard MDM3100 has RS-485 communication protocol, 2 energy pulse outputs (active and reactive each) functions.
With optional modules, MDM3100 can perform more functions: harmonic analysis, 8 digital signal inputs, 4 programmable relay outputs, 4 programmable analog outputs (0-5V or 4-20mA), data storage, Profibus communication, Ethernet networking capabilities.
MDM3100 fulfills all the important
requirement of IEC 60668;IEC61557-12; IEC6
EMC
and other safety standard
