UMG 20CM

20 Channel Branch Circuit Monitoring Device with RCM

Main features

  • RCM

    Powerful RCM residual current monitoring already detects leakage currents in their initial stages before they cause system failures or even fires. It is already integrated in certain UMG measuring devices. The measuring current transformer that is required can be installed manually at a later date if required. Continuous RCM monitoring increases the system safety and availability significantly. In specific applications such as the data centre, residual current monitoring is essential due to the high availability requirements.

  • 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.

  • Alarm management

    The alarm management feature in GridVis® monitors all measurement parameters captured by the UMG measuring devices. It comprises escalation management, a logbook function and user management for individual notifications by e-mail, dialogue box on the monitor, etc.

    In addition to monitoring effective values, short term interruptions and transients, as well as communication with the measuring devices can also be monitored.

  • 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.

  • Current channels

    While power quality analyses and energy management play a central role on the main feed-in, individual currents are recorded in sub-distribution.

    The UMG 20CM energy and residual current measuring device has more than 20 current channels for this, i.e. connections for current measurement transformers. Therefore, operating currents of up to 600 A and residual currents from 10 mA to 1000 mA can be recorded.

Areas of application

  • Continuous acquisition of the operating currents
  • Permanent residual current monitoring
  • Messages in the event of the nominal current being exceeded
  • Energy acquisition for complete current distribution
  • Cost centre accounting
  • Transparency of energy costs
  • More effective use of IT infrastructure
  • PDUs in data centres
  • Increase of high availability power supply
