The prototypes are further controlled thanks to the additional tests.We check that all our inductors respect the applicable regulations and laws in the electrical field.
As well as complying with the EN 60289 regulation, EMG® inductors are homologated cCSAus, therefore can be marketed and sold across North America. The Canadian Standards Association (CSA) checks and certifies that the products are compliant with the applicable standards in terms of safety and/or performance and it is the main mark in Canada. UL is the certifying mark for the United States of America. Thanks to an agreement with UL, CSA certifies the compliance of a product with all the applicable regulations for both the American and Canadian markets. This compliance is indicated by the cCSAus mark - featured by our inductors.
Our products are highly customisable, therefore the descriptive parameters indicated in the catalogue are provided as a guide. According to the customer needs, the data is adapted to the desired product type.
Harmonic distortion test to check the real working conditions of our inductors
We short-circuit the inductor and supply it with highly partialised voltage so that the nominal current can circulate. This current is notably distorted: the average THDi value recorded is 45-50%. The high voltage partialisation tends to put the magnetic circuit under strain and to highlight any noise problems that would not be detected at 50 Hz frequency
