IMPULSE WINDING TESTER MODEL 19301A
The Chroma 19301A impul se Winding Tester combines high & low inductance test technologies, has a maximum impulse voltage of 1000V, and a high speed sampling rate of 200MHz which satisfies most of the test requirements for power inductor products with a wide inductance range from 0.1uH to 100uH. The built-in functions of Area Size Comparison, Differential Area Comparison,FLUTTER Value, LAPLACIAN Value, ΔPEAK
or ΔPEAK RATIO,PEAK RATIO and ΔRESONANT AREA functions are able to inspect coils for poor insulation effectively.
The inspection of wound components for production includes the electrical characteristics test and the withstand voltage test of the electrical safety standard. Poor insulation of a coil, which is a common issue that causes layer short and/or short circuit with the output pin during use, can be caused by bad design,bad molding process, or deterioration of the insulation material. Therefore, it is necessary to perform the layer short test on any winding component or coil.The 19301A, which is specifically designed for wound component tests, utilizes a high voltage & low capacitance capacitor (low test energy) in parallel with a coil to form an RLC
resonant, which is called damping. Analyzing the decay of the waveform via an analysis technology with high speed, precise, and accurate sampling can successfully detect poor insulation within a coil. It provides the
winding quality test and the withstand voltage test on the cores for power inductors, and also makes the manufacturer and user checks of the quality of winding component products more efficient.
The 19301A can beused to test low inductance winding components with a minimum inductance down to 0.1uH. It provides 4-terminal (4-wire) measurement,contact checks, inductance check and voltage
compensation for testing low inductance winding components in order to avoid gross inaccuracies in test voltage caused by the inductance variation of the DUT or the equivalent inductance of wires, which makes it
the best impulse winding test instrument for low inductance winding components.
The 19301A has an extremely high test speed that can reduce testing times and increase productivity in automated production. In addition, the voltage compensation function reduces the impac t of the equivalent
inductance of the wiring in automated machines.
The brand new Human Machine Interface has a colorful display and screen capture function.
The screenshot of the waveform, which is not only suitable for the on-site production but also applicable for R&D and Quality Assurance to analyze and compare, can be saved through the USB port on the front side of the instrument. This improves the convenience of operation.
