5V AC RMS Output Rogowski Coil Integrator Current Transformer

  DTP integratorDTP is a THREE PHASE DIN-RAIL Vac/dc Output Rogowski coil integrator installation in distribution box,in a plastic 1 module DIN-RAIL enclosure, powered directly from the mains.What does Integrator do?• Rogowski coil output is weak voltage mV signal,DTP has ability to amplify and convert it to standard signal which could be catched by multimeter and scope.• Rogowski coil output is proportional tothe frequency of the measured current, the signalequalization ensure a linear response on a widefrequency range. DTP allows to use coils on differentelectrical network frequencies, keeping the sameoutput 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.FeatureDTP can be combined with any model and size of Y-FCT or FCT Rogowski coils.The available values are: 5Vac,4.5Vdc,4-20mA.On request the input value can be customized according to the application.DTP and Rogowski coil is a very flexible system, suitable for high power load analysis, impulsivecurrent monitoring, DC ripple measurement, etc.Due to its specific features, flexible Rogowski coil is an extremely comfortable solution for current measurement and can be used in a number of cases where traditional current transducer is not the adequate solution.  Advantage• High read accuracy 0.5%  • Compact DIN-RAIL construction• Low power consumption •Lower zero drift down to 5mVRelated ProductsY-FCT,FCT,NRC,MRC  ApplicationsMeasuring devices, lab instrumentation•Power monitoring & analysis• Harmonics and transients monitoring• Welding machine control• High current measurement What is a Rogowski coil?Rogowski coils have been used for the detection and measurement of electric currents for decades. They are based on a simpleprinciple: an "air-cored" coil is placed around the conductor in a 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. This voltage is integrated, thus producing anoutput proportional to the current.By using precision winding techniques, especially developed for the purpose, the coils are manufactured so that their output is notinfluenced 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.They 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 the structure without hardcore, the coil can       be easily manufactured according to the application or to the available space.• 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 being measured.The transducer does not measure direct currents but, unlike a current transformer, it can carry out accurate measurements of ACcomponent even if there is a large superimposed DC component, since there is no iron core causing saturation. This feature isparticularly useful for measuring ripple currents for example in battery charging systems.Specification  ModelDTP.1DTP.2DTP.3Rated output5V AC rms4V DC(true-rms)4-20mAMaximum Output(overload)10V AC rms4.5V DC25mA DCOutput Ripple factor1%Default 5% (relay to Response time)Response time≤1usDefault 100ms(adjustable)Power consumption200mW300mWBandwidth10Hz to 10kHz30Hz to 1kHzPower supply12V or 24VRated Input100A600A1000A3000A6000ARead Accuracy0.5% typical at 1%(≥10A) to 120% of rated Current @25ºCPhase error≤0.5°Linearity±0.2% of reading(1% to 200% of range)Minimum Current measurement1A (Ripple 100mA)Output on 0A    (zero drift)≤5mV(rated outut ≥2.5V:zero drift
