Possible interfaces:
KBR eBus*, Modbus*, Profibus*, KBR eBus TCP*, Modbus TCP*

*depending on the device type

Three-phase network measuring device multimess F144 LED

The electronic network measuring devices of the multimess F144 LED series measure and monitor all important parameters in the three-phase network and are available in a wide range of performance classes.

The load profi le of the facility measured in 15-minute measuring intervals can be saved for up to 366 days, depending on the model. The integrated event memory can log up to 1500 events, such as limit violations, power failures, voltage dips, etc.

 

Highlights

  • Measuring accuracy according to DIN EN 61557-12
  • Separate current transformer input for neutral conductor current
  • PE ground leakage current is displayed
  • Several performance classes for all fields of application
  • Extensive displays, functions and storage options
  • Optimum readability thanks to bright LED displays
  • Wide range of variety of inputs and outputs (digital/analog)
  • Small mounting depth of only 60 mm
