Universal measurement device for DIN rails

Universal measuring devices of the UMG 103 product family are mainly designed for use in low voltage distribution systems.

Main features

  • Harmonics

    Harmonics occur due to operating equipment with a non-linear characteristic, e.g. transformers used in saturation, energy saving bulbs, frequency converters and power electronics. They cause a load on the mains due to additional currents and can affect or even destroy operating equipment. This mains feedback can be detected and documented using power quality analysers.

  • Modbus-Schnittstelle

    Many UMG measuring devices have an RS485 interface with a Modbus RTU protocol, which enables extremely cost-efficient networking. It features simple topology configuration and a lack of sensitivity to EMC interference. Communication between the sender and the recipient takes place on a wired basis via a sheathed, twisted pair cable.

  • GridVis®

    GridVis® is a comprehensive and scalable piece of software for setting up an energy monitoring system and monitoring the power quality. It is used to both program and configure many UMG measuring devices, as well as to read, process and analyse the measured data. Typical applications are energy supply, industrial systems, facility management, etc.

  • Threshold value monitoring

    Threshold value monitoring can be assigned to both alarm management and switching operations. Corresponding UMG measuring devices have digital outputs that are suitable as switch outputs. Therefore, certain reactions can be automated if a threshold value is exceeded or not reached.

Areas of application

  • Measurement and checking of electrical characteristics and energy consumption in energy distribution systems
  • Cost centre management
  • Threshold value monitoring, measured value transducer for building management systems or PLC
  • Monitoring of harmonics
