EMC Specifications
External Filter (class B)
Required external input filter in order to meet class B in
EN 55022, CISPR 22 and FCC part 15J.
The PKF power module is mounted on a double sided Printed
circuit Board (PB) with ground plane during EMC measurements.
The fundamental switching frequency is 510 kHz 5% @
IO = (0.1…1.0) × IOmax.
