Product Description 1. SummaryTH0420 is A precision coaxial shunt with ultra-low power coefficients. Each set contains A total of 10 different current range specifications and can convert nominal current from 0.1 A to 100 A to nominal voltage output of 1 V or 0.5 V. TH0420 has a very low power coefficient, such as TH0420-100A even under 100 W power conditions, its power coefficient is not more than 10 PPM, very suitable for a wide range of AC and DC current rapid measurement.2. FeaturesOperating frequency: DC ~ 100 kHz Nominal input current: 0.1A ~ 100A (wider range can be customized) Nominal output voltage is 1 V or 0.5 V Annual variation: typical value is 5 ppm, maximum value is 16 ppm. Ultra low power factor Can withstand the instantaneous current impact3. Applications☆ Build Wide Frequency Current Measurement SystemSet up wideband current measurement system with wideband current source and wideband standard voltmeter (such as TH2000 vector voltage analyzer), measure wideband current signal, and calibrate wideband current source and wideband ammeter, etc. ☆ Build Wide Frequency Power/Energy Precision Measurement SystemSet up wideband power/energy precision measurement system with high frequency V/V conversion standard and TH2000 vector voltage analyzer, measure wideband power/energy signal, calibrate wideband power source, wideband power meter, power analyzer and other equipment. Build Wide Frequency Transformer/Sensor Calibration System Set up a wideband transformer/sensor measurement system with wideband constant-current source and wideband sensor tester (such as TH2000 vector voltage analyzer) to calibrate the tested transformer or sensor with nominal current ≤ 500 A.Build Wide Frequency Transformer/Sensor Calibration SystemFor the calibration of transformer/sensor whose nominal current is greater than 500 A, TH0420 is used as the standard and the secondary signal I/V converter of the equipment under inspection, and a wideband transformer/sensor measurement system is established with a wideband constant current source and a wideband sensor tester (such as TH2000 vector voltage analyzer).4.

Note [2]: When the coaxial shunt is used to measure DCI, the resistance's own heat will lead to the change of resistance value under different input currents, thus introducing the error. The calculation formula is as follows: γ= power coefficient × [1-(current measurement/nominal current value)^2]4.2 Current MeasurementSpecificationNominal input current ( A )Nominal Output current ( V )AC/DC difference[3] ( k=2,±ppm )53 Hz1 kHz10 kHz100 kHzTH0420-0.1A0.1120252525TH0420-0.2A0.2120252525TH0420-0.5A0.5120252525TH0420-1A1120252530TH0420-2A2120303550TH0420-5A5120305080TH0420-10A101203050100TH0420-20A201203050100TH0420-50A501305080150TH0420-100A10013050100200Note [3]: The measured value of AC current should be calculated according to the following formula, and the unit of the difference between AC and DC is ppm: Ac current measurement value =https://tunkia.en.made-in-china.com/product/MTIYLKxCZecB/(voltage measurement value/calibration resistance value)×(1+ AC-DC difference /(1 000 000)) SpecificationMaximum current( A )Instantaneous current (<5s)SpecificationMaximum operating current( A )Instantaneous current (<5s)TH0420-0.1A0.2 A1.5 ATH0420-5A5.5 A20 ATH0420-0.2A0.5 A2 ATH0420-10A11 A30 ATH0420-0.5A1 A3 ATH0420-20A22 A50 ATH0420-1A1.5 A4 ATH0420-50A55 A100 ATH0420-2A2.5 A6 ATH0420-100A110 A200 A4.3 Phase DisplacementSpecificationPhase Displacement ( k=2, ±μrad )53 Hz400 Hz1 kHz10 kHz50 kHz100 kHzTH0420-0.1A551030150300TH0420-0.2A551030150300TH0420-0.5A551030150300TH0420-1A551030150300TH0420-2A10101550300600TH0420-5A1015251005001200TH0420-10A1020401508001600TH0420-20A10255020010002000TH0420-50A10306530015003000TH0420-100A20408040020004000 5.
