Imagem Plataforma

Avaible for measuring and analyzing electrical quantities, IoT-ready facilitating energy management and simplified, secure MQTT publishing.

  • Compatible with WEG energy management platforms (software not included, see WEG Digital Solutions catalog);
  • Analyzer configuration software, WEG Power Maneger 4, for instantaneous and mass memory reading of the individual device;
  • Compatible with various brokers, MQTT protocol that follows the "Publisher/Subscriber" model for exchanging messages;
  • Publication of the measured electrical quantities in a JSON-based format;

Description

The MMW family of multimeters and energy analyzers has functions for reading and calculating electrical quantities. In addition to multimeters, the energy analyzer also provides monitoring, analysis and control of an electrical system. It is capable of advanced applications such as energy measurement, recording of electrical parameters and programmable digital inputs and outputs. See also model MMW03.

The MMW04 multimeter and energy analyzer provides visualization and recording of current, voltage, power factor, power, demand, energy and hamonics on the display or in software. Through MQTT it is also possible to publish to supervisory systems or the cloud for energy management.
