High-precision Rogowski signal integration
Stable 4–20 mA output – industrial standard
Wide frequency range – suitable for harmonic and fast dynamic process analysis
Stable and linear signal across the entire operating range
Compatibility with different Rogowski coils

Applications

Engineer / R&D specialist: An excellent choice for testing power electronics, inverters, electric drives, and high-current systems where extremely accurate current measurement and reliable signal transmission to PLCs, data loggers, or analyzers are required.

Electrical and measurement laboratories: With ±0.2% accuracy and a stable 4–20 mA signal, the integrator is suitable for reference and comparative measurements, as well as calibration benches where long-term stability is essential.

Industrial engineering (high requirements): Ideal where 0–10 V or 333 mV solutions become unreliable due to noise or long distances. The 4–20 mA output ensures safe and accurate data transmission even in demanding environments.

Pros

Very high accuracy – ±0.2%
Industrial 4–20 mA output
Wide frequency bandwidth (up to 20 kHz)
Suitable for professional testing and laboratory use

Cons

Fixed rated current – must be selected before ordering
AC current measurement only
Not a DIN-rail solution (laboratory-oriented)
Requires an external DC power supply
