It will output a variety of items about class loading, and this may well provide you with clues as to what the actual dilemma is.
In fact, it could probably have ways that straddle zero but supply some sub-threshold voltage of a dilemma duration. I was shocked to check out science imitating art so properly in your "bottom from the barrel" waveform. Not all Lively PFC power supplies could have issues with all non-sine wave UPSs, but some don't perform jointly and Here is the explanation why. +1 for your science.
A hybrid (double conversion on demand from customers) UPS operates as an off-line/standby UPS when power circumstances are inside a certain preset window. This allows the UPS to achieve extremely large effectiveness rankings.
As applies especially to this thread and wattage rankings, a PSU with active power aspect correction might really draw more power when important to correct for misaligned current. This is achievable anytime as power shipping and delivery is never perfect, but way more possible when The present is riding a squared off wave.
