Short description:
The current transducer measures both 0–1 A and 0–5 A AC/DC currents, while conver-
ting the input signal to a standard analog signal at the output.
Features:
• PC configuration interface
• True RMS measurement or arithmetic mean value
• Digital switching output (configurable switching thresholds)
• Switchable filter function
• Switching between measuring ranges is calibrated
• Safe 3-way isolation with 2.5 kV test voltage acc. to EN 61140
• Extremely fast response times
• Measuring range overflow indication
