#KiPrim power supply Is very noisy, 600mv AC on 5V 2Amp load. Testing a low pass filter from Amazon with a very surprising results! #Siglent #OWON

Same signal from an RC circuit powered by the noisy #KiPrim DC310S on both #Rigol #DHO900 & DS1202Z-E scopes using same 150Mhz probes in 1X. The difference in signals is the DS1202Z-E & kiPrim psu are earth referenced.

#KiPrim (#OWON) DC310S & #Hanmatek HM605T have an identical startup, probably very similar circuit design. However the KiPrim DC is very noisy.

Pushing the limits of a budget buck converter from #Amazon running it for an hour at 2.6A load. I used Elegoo Wash & Cure cover is case a cap blew. #Electronics #Siglent #KIPrim

Still very noisy #Kiprim (#OWON) power supply after adding ferrite core to ground with 2 turns, but improving. #Electronics #Siglent still figuring out why the AC noise is synced on DC. See pink trace.

I've been having weird issues with circuits powered by the #KiPrim DC power supply and decided to check on spectrum analyzer. 50ohm term on the scope and 20dbm attenuation on the Siglent. Most of the noise is harmonics above 1Mhz.
