TNY-268 Noise
Posted by: R11
on
I'm using the TNY-268 and experiencing high conducted emissions which is causing failed CE testing.
Is there someone who can take a look at the schematic and see if you can find somethign to help? Many things have been tried but the noise is still an issue. This project needs to hit production soon.
Input V= 208 – 600 Vrms
Input f = 45 – 70 Hz
Output V = 12 VDC
