Functions and features of the UMG 801

All-in-one power analyzer

  • All in one device

    • The basic device has:
      • 8 current measurement channels with 1/5 A inputs
      • 4 Multifunction channels, optionally configurable as RCM, temperature measurement channels or additional current measurement channels
    • Extensive measurement data memory with 4 GB for storage of measurement data
    • Two groups with four digital IOs each (tariff changeover and pulse input, logic states)
    • Analog output (DC 0/4-20 mA)

  • High-precision measurement

    • High sampling frequency (51.2 kHz voltage)
    • 1024 Samples for the voltage measurement
    • High measurement accuracy on all channels (V: 0.2% / A: 0.2% / kWh: class 0.2)
    • Maximum safety: 1000 V CAT III
    • Extensive power quality parameters
      • Voltage up to 127th harmonic and interharmonics – THD-U and THD-I
      • THD-U and THD-I
      • unbalance
      • Event and transient detection

  • Visualizing, documenting and analyzing

    • Comprehensive options for visualizing, analyzing and documenting energy measurement data (GridVis® software)
    • Integrated automatic report generation (GridVis® software)
    • Integrated color graphic display for visualization and intuitive configuration on site

  • Managing and using Data

    • Various interfaces for simultaneous use
      • 2 Ethernet interfaces
      • RS485 interface for data readout and can be used as gateway
    • Comprehensive protocols and services (OPC UA and Modbus)

  • Profit from OPC UA

    • Easy integration of measurement data from the basic device and measurement modules into higher-level systems (e.g. building control systems, SCADA systems)
    • Cyber security: Integrated security mechanisms to protect against unauthorized access and misuse
    • Configuration of the entire measuring system via OPC UA
    • Future-proof software architecture as the OPC UA standard evolves with new applications
