[time-nuts] potential low-RFI power supply

[Eric Scace]

Pro Audio Engineering announced a sale (through Friday) on its nominal 14 Vdc 4A switching supply <https://proaudioeng.com/products/pae-kx33-low-rfi-ac-power-supply/>. The test results <https://proaudioeng.com/products/pae-kx33-low-rfi-ac-power-supply/> webpage compares noise on the DC output and noise frequency spectrum under a variety of conditions with a lead-acid battery, an Astron linear supply, and a variety of switching supplies from other manufacturers.

I have not used this and can’t vouch for its performance. Given recent discussions here on supplies, the analysis might be interesting. At least the supplier has attempted to quantify the performance of its power supply and make that information available to the prospective purchaser.

It would be interesting to see comparable (or more suitable) measurements made by others posted here.
