The AO-S9 is a Rogowski mini coil integrator that combines with a power meter or PLC in a plastic enclosure powered directly from the mains.

What does Integrator do?
• The Rogowski coil output is a weak mV voltage signal, AO-S9 has the ability to amplify it and convert it to a standard signal that could be trapped by the Meter and Range.
• The output of the Rogowski coil is proportional to the frequency of the measured current, the equalization of the signal guarantees a linear response over a wide range of frequencies. AO-S9 allows to use coils in different frequencies of electrical network, maintaining the same level of output on the frequencies.
• An integrator is essential for equalizing and displacing the output signal of the Rogowski coils by 90 °. It consists of an active electronic circuit with insignificant deviation and good linearity.

AO-S9 can be combined with any model and size of AO-YTFC or AO-TFC Rogowski coils.
The available values ​​are: 0-10VDC, 0-10V peak, 333mV rms.
On request, the input value can be customized according to the application.
The AO-S9 and Rogowski coil is a very flexible system, suitable for high power load analysis, impulse current monitoring, DC ripple measurement, etc.
Due to its specific characteristics, the flexible Rogowski coil is an extremely comfortable solution for the current measurement and can be used in a number of cases where the traditional current transducer is not the right solution.
