Short description:
The Rogowski transducer records RMS values from alternating currents via a Rogowski coil, con-
verting 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
