Who knows, perhaps when the APS unit arrive back to me (after some changes in the unit state) it will be effective (means good sounding) at 70-80% of load as much as it was at 10%... If it happens then I might have a phenomenal solution for my powerlines frustrations. I will be posting later but so far my tail is still trembling…. |

With my anticipation of PurePower regenerator delivered back tomorrow after APS guys fixes it I went today to MIT fleamarket and bought a current probe in order to see how good or bad my Super Milq’s load is and to assess objectively the Super Milq’s power factor. I have explained to APS guys that Melquiades, with its input choke filters, should be at superbly simple load. Now I have the objective data to back up my claim.
Here is my dedicated power line driving at purely resistive load. The sharp sinusoid above so it voltage, and the unfocused one below is current.
The next image is the resistance load replaced with 258W of Super Melquiades. Old 4 power supplies are input chokes and all of them properly implemented with voltage in each half-period returning back to zero. As far as I concern it looks extremely good, without even phase shift between voltages and current.
Interestingly that when I asked Dima look at the measurement then he informed me that the Melquiades load should be even easier for any regenerator then purely resistive load, as Melquiades does not have even sinusoidal draw of current but rather the circles was vertically folding walls - that according to him is the most optimal load ever. Also it was interesting is that looking at the picture he told lots about the performance of my input choke filters, which according to him where “properly implemented and functioning”. It was very educational lecture…
Some you might be concerned by clipping of the current peaks. Do not be. These clippings are because I drive the thing directly from power lines and as you can see the voltage is clipped. Below are two images Voltage vs. Current when I drive my Melquiades by PS Audio regenerators (that outputs a perfect sinusoid). As you can see the Current characteristic and Power Factor are exemplary. Long live to the input chokes….
Okay, now I see I'm ready to experience what the “revised” APS PurePower will do. BTW,just for references: here are power factor signatures some other my components that us CRC filtration.
