Power Line EMI Adapters
-
How much EMI noise is on your power lines indeed? How to assess the levels of noise and its properties when it is obviously a bad idea to connect your oscilloscope or a spectrum analyzer directly to your power lines?Our EMI interface adapters provide a barrier for high mains voltages but a straight passage for high-frequency signals so that you can connect your sensitive instrument to power lines for analysis and quantification. We offer plug-in and hand-held adapters which can measure both differential ("normal") and common-mode noise.

End of Line Noise Test System
-
End of Line Noise Test Systems from VIacoustics are designed to support end of line product noise testing on factory floors and quality assurance environments. Using the Limit Analysis features of the Nelson Acoustic Trident software, users can set noise emission maximum, minimum or control range criteria based on Awtd and/or 1/N octave band criteria. Criteria can be customized for most any type of product based on the noise emissions of known good and bad units. The large front panel Pass/Fail indicator allows operators to quickly determine if units meet the criteria. Data on units that fail can be exported for further analysis.

Air Core Line & Load Reactors
-
Line and load reactors are generally serial-connected to the input and/or output terminals of three phase equipment such as motor speed controllers, inverters and UPS systems. These equipment make use of semiconductor switches such as IGBTs, thyristors, and diodes and therefore create harmonic distortion and high switching over-voltages (dv/dt). Use of such equipment has been becoming more widespread as the technology advances. However, the negative effects of these equipment should not be overlooked.
