The Purepower state at their site that efficiency of the unit is 89-92% depending on load. I presume that they meant the power factor correction that need to be taking to the consideration. In my case my two 6-ch Melquiades run from two new PP2000. Melquiades are hugely inductive load so there is no phase lagging of current vs. voltage. How it affect power factor I have no idea – the power factor is a consent that I do not purely “get”.
Anyhow, the fully warmed Milq get 330W if stable draw. The PP2000 shadows for whatever reasons the 28% load – the PP2000 is generally clueless what it shows. The PP2000 sucks from the walls 415W that makes the PP2000 is a bit sub efficient 80% .
So, two PP2000 units will suck ~ 850W from the lines, I wonder is any way to cheat with this electricity by playing the power factor correction games. I know that in Europe are very popular small power correction devises that allowing the load to draw higher current but make the sensors that measure the cost of electricity do not spin and do not report it. Warn you that they are perfectly legal ways to save money and I do not call for tempering with electrical meters. The power correction saving is legal and I wonder if I can engage it before the PP2000 and if it has any worsening effect to sound.
The European guys, can you advise some 220V power correction stations, I think I will be able to accommodate them in US (in US we in fact have 220V, single phase in residential homes, juts just use a half).
