Description
Description JUMPFLEX transducer; Rogowski transducer 
Remarks Item description:

Short description:

The Rogowski Signal Conditioner records RMS values from alternating currents via a Rogowski coil and converts the input signal into a standard analog signal on the output side.

Features:

  • PC configuration interface
  • Supports different types of Rogowski coils
  • Digital switching output (configurable switching thresholds)
  • True RMS measurement (TRMS)
  • Configurable output signal
  • Configuration via DIP switch
  • Safe 3-way isolation with 2.5 kV test voltage acc. to EN 61140
  • No current bar interruption during installation
  • Measuring range overflow indication
