This product is a series noise filter for power mains for your audio system and started asa P2P on the bench and has been under development for some time now. I am pleased to say that the production prototype has been completed and passed CE and FCC testing and certification.
It is a 5th order Chebyshev filter built with premium name brand components including two massive 19.5mH 10A 1000v PCB mounted CMC chokes. It should provide about -50dB of noise attenuation at 100kHz and more at higher frequencies. This should significantly reduce SMPS noise in power lines. Good news is that it is rated for 10A and works from 85VAC to 230VAC and has combo NEMA/Schuko plug receptacle on the front.
Here is a render of the final product. I don’t have the final in my hands yet.
But here is a photo of the inside from the test lab:
This was my bench testing of an earlier prototype with 2.5mH inductors. We later moved to larger inductors and smaller Y2 capacitors to reduce parasitic dissipation to comply with CE requirements. This had a huge impact on the cost of components as you can imagine going from a 2.5mH to Kemet 19.5mH 10A CMC - but makes for a well engineered, safe, energy efficient, and robust electrical appliance that will clean up noise like a black hole.
Testing below verified -50dB at 100kHz noise removal.
