The P10 is loaded at 80% under MULTI. Switching to SINE shoots load to 93%. Why is that ?
If I reduce the MW strength from 6 to 1 under MULTI the load moves from 80% to 87%. Why is that ?
In the first case the yellow indicators pops up (as expected) and in both case a audible hum appears
i thought MULTI would increase the load, but rather it seems to reduce it.
There can be some various inefficiencies going on here but a delta of 13% and even 7% does seem high. The fact that you’re running this big of a load definitely has something to do with it. I’m going to ask the team and see what they’re thinking is.
Mulitwave “fattens” the sine wave coming from the wall.
Voltage out of Powerplant is same in RMS for Sine and Mulitwave.
As Multiwave is “fatter” the peak voltage of multiwave will be lower.
The peak is largely what drives components, and power supply caps use the peak for charging.
So using multiwave will “starve” your equipment of peak voltage and lower the power they consume.
Hence you see lower power output with multwave on than on sine wave.
I think this implementation is wrong and go against the idea of multiwave. A more correct way to do it would be to maintain peak when turning on multiwave. I could see people being nervous though wiht voltage RMS which is what is displayed going up. The workaround is to increase output voltage when using multiwave so that you get same peak as for sinewave. This should be around 7% for full multiwave.
