IEC 61000-4-28
IEC Â 61000-4-28: Electromagnetic Compatibility (EMC) - Part 4-28: Testing and Measurement Techniques - Variation of Power Frequency, Immunity Test for Equipment with Input Current Not Exceeding 16 A per Phase The purpose of this standard is to establish a reference for evaluating the immunity of electric and electronic equipment when subjected to variations of the power frequency. It applies to electric and/or electronic equipment connected to 50 Hz or 60 Hz distributed network with rated line current up to 16 A per phase. Preview Standard
