Sometimes when you're stuck in a deep hole it's best to stop digging. It is most definitely unplugged. link
Then posted nonsense with disparaging comments. And still not post even one manufacturer spec number. "Go ask APC" simply confirms you cannot even read specification numbers. You cannot post what you do not even understand. So you reply nasty.
Again, APC doesn't not list THD. You have a total and utter reading comprehension problem. For those people following along at home and laughing hysterically at Westom's hitting rock bottom and starting to dig. Here's a link
to APC's specs. Note the lack of a THD spec.
Output from a typical UPS is some of the ‘dirtiest’ power an appliance will see. A typical 120 volt UPS may output two 200 volt square waves with a spike of up to 270 volts between those square waves. See? Numbers.
Still not true. Most output a stepped square wave like this:
However, I bet if you keep repeating your lies enough someone else might believe them. Clearly it's working for you.
Hearsay describe this as clean power when basics are not learned. It was called a modified sine wave, a stepped sine wave, or some other sine wave. Then the naïve relabel it as a 'pure' sine wave. Why does APC not provide specs such as THD? Then everyone would know it is not a pure sine wave.
You're still wrong. I've proven it and you've got your head in the sand. APC says
, "Smart-UPS feature a 16-segment LED display, extended range automatic voltage regulation (AVR), and pure sine wave output on battery" Yup, clearly I made up the 'pure' part.
Stereodude was asked to supply manufacturer spec numbers.
I can't give a THD spec that APC doesn't give. I've linked to the specs that APC does give.
He could not even do that. He has no idea what those numbers mean.
I know what Total Harmonic Distortion is.
So he does what the naive routinely do. He says, "Ask APC."
Yes, it's naive to expect the person demanding unlisted information to call the manufacturer and request it.
The only thing curious here is how your able to be so blind to reality.
APC claims a pure sine wave output
APC does not even claim what Stereodude posted.
. I've showed the graph of it. I see you're still unable to read...
Only Stereodude invented that myth.
Ahh... the "myth" that's not a myth. The same one that I didn't invent either
A myth provided without any numbers.
Numbers or not, it's still not a myth. Unless you've redefined "myth" to mean a fact you're clueless about.
No numbers is the first indication of a lie.
Nah, words coming from you are the first indication of a lie. You're the one who hasn't provided any proof or evidence.
So he gets nasty to mask those missing numbers and his missing technical knowledge.
Yes, clearly you're the one with the numbers and all the knowledge. AVSforum is lucky to have you!!!
He did not even do those sine wave pictures. But somehow knows how they were taken.
Because unlike you I know how to read and comprehend. I read how the measurements were taken. I have no doubt you'll shortly claim that Jesse Kovach didn't know what he was doing though.
Nasty because he backup anything with citations, manufacturer specs, and fundamental numbers. He does what so many myth purveyors do. Attack the messenger when caught lying.
The only person lying here is YOU!
You have shown an innate ability to lie, misrepresent, misunderstand, misconstrue, deny, and pretend. Keep up the good work. I'm pretty sure you have a future in politics.
