ATEC MDM3100 Multifunction Power Meter

ATEC MDM3100 is a powerful Multifunction Power Meter that measures more than 60 parameters such as U I P, Q, cos, F, kWh, kvarh, etc. The standard MDM3100 has RS-485 communication protocol, and 2 energy pulse outputs( active and reactive each) functions. With an optional module, 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, and Ethernet networking capabilities. MDM3100 fulfills all the important requirements of IEC60668; IEC61557-12; IEC61000-4-30 and CE standards as LVD EN61010; EMC EN62052-11 and EN62053-21.
