DC Blocker Section
It is calculated to handle max. current of up to 16A
– On the board are mounted 6 discrete high-power diodes 10A4 which yield the max. DC Blocking voltage of approx. 2V.
– two MASSIVE 47 000 uF EPCOS capacitors (the bigger is capacitance, the higher are handled currents).
– one 10W power resistor.
– one bypass WIMA MKS4 400VAC capacitor.

Common Mode Filter Section
It is calculated to have a corner frequency of approx. 20 kHz and max. handled current of 20A with the parts used
– 4 pcs. X2 type safety polypropylene capacitors
– 2 pcs. Y2 type safety polypropylene capacitors
– Triad Magnetics Common Mode Choke, rated at 20A
