Somewhat related question to the T-amp power supple thread below. I thought I should start another thread given the devices are different.
I am interested in "quiet" linear regulated ps for my home network appliances. By "quiet", I'm thinking of minimal digital noise, ripple, emi/rfi.
Referencing the T-Amp recommendations, are these same products being recommended along those performance lines?
I recognize the Jameco and Pyramid and older references to Aacopian, but see a number of others that look like traditional lap top switching (noisey) power supply bricks. Are these (later) all known to be quiet?
All my appliances are fairly minimal loads;
Cable Modem 12 VDC 0.75 Amps
mini ITX FW/Router 12 VDC 6.5 Amps
Cisco Switch 12 VDC 1.0 Amps
I've read some manufacturers are starting to use "quiet" switching power supply and I would be very interested in those if they exist for this application.
Is there a criteria to review to qualify a "quiet" ps? some noise or ripple measurement?
Thanks
