Rogowski coil integrator AO-DA05-1

INTEGRATOR AO-DA05-1
-  AO-DA05-1 is a 5A output Rogowski Coil Integrator,.
-  Its power supply is 24V dc，≤15W
-  AO-DA05-1 complies with standard clamping-track installations.

What does Integrator do?
•  Rogowski coil output is weak voltage mV signal,DA05-1 has ability to amplify and convert it to standard signal whichcould be catched by multi-meter and scope.
•  Rogowski coil output is proportional to the frequency of the measured current, the signal equalization ensure a linearresponse on a wide frequency range. DA05-1 allows to use coils on different electrical network frequencies, keepingthe same output level over the frequencies.
•  An integrator is essential to equalize and shift by 90° the output signal from the Rogowski coils. It consists of an activeelectronic circuit with negligible offset and a good linearity.

Features:
a.  DA05-1 can be combined with any model and size of Y-FCT, NRC or ZRC,MRC Rogowski coils.
b.  The available values are:0~5A AC.
c.  High bandwidth from 30 to 5kHz
d.  On request the input value can be customized according to the application.
e.  Due to its specific features, flexible Rogowski coil is an extremely comfortable solution for current measurementand can be used in a number of cases where traditional current transducer are not  adequate solutions.

-  Rogowski coils have been used for the detection and measurement of electric currents for decades. They are based on a simple principle: an “air-cored” coil is placed around the conductor in toroidal fashion and the magnetic field produced by the current induces a voltage in the coil. The voltage output is proportional to the rate of change of current. When this voltage is integrated, it produces an output proportional to the current.
-  By using precision winding techniques, especially developed for the purpose, the coils are manufactured so that their output is not influenced by the position of the conductor within the toroid, and to reject interference from external magnetic fields caused, for example, from nearby conductors.
-  Basically, a Rogowski coil current measuring system consists of a combination of a coil and conditioning electronics.Rogowski coil current transducers are used for the AC measurement.
-  Rogowski coils can be used in similar circumstances to current transformers but for many applications.

They have considerable advantages:
•  Wide dynamic range.
•  High linearity.
•  Very useful with large size or awkward shaped conductors or in places with limited access. Thanks to thestructure without hard core, the coil can be easily manufactured according to the application or to the availablespace.
•  Unlike traditional current transducers, there is no danger from open-circuited secondaries.
•  They cannot be damaged by large overloads.
•  They are non-intrusive. They draw no power from the main circuit carrying the current to be measured.
•  They are also light weighted and in some applications are light enough to be suspended on the conductor beingmeasured.
-  The transducer does not measure direct currents but, unlike a current transformer, it can carry out accuratemeasurements of AC component even if there is a large superimposed DC component, since there is no iron corecausing saturation. This feature is very useful to measure ripple currents for example in battery charging systems.
