phansonmba Posted January 18, 2021 Share Posted January 18, 2021 My newly acquired DC regulated switching power supply (Chinese) appears to be sending noise back through my main AC line. I use this power supply to power circuits under test. This is causing interference on both my laptop computer and my AD2 that I run off of it. All of these devices (Power supply, laptop & AD2) are all connected to the same surge-protected power bar to ensure that they all have the same ground potential and to minimize ground loops. Plugging the laptop and AD2 into a different outlet/circuit does not fix the problem. The noise seems to be circulating through my entire AC mains system. I only notice these interference problems when the DC power supply is turned on and they all disappear when I turn it off. Any suggestions as to how I can eliminate this problem short of replacing the power supply? Link to comment Share on other sites More sharing options...
