Hi Everyone

When I purchased my Rupes 15 a short while ago I noticed my machine to have had some subtle changes and my suspicions were confirmed on a thread I created in the Rupes section. Consequently, I purchased a Flex 3401 and knowing its advertised 7.5A 900W, I actually found a difference. Bare in mind I am in a 230V region, my documentation/manual/guide and sticker on the polisher clearly state 4.1A 1010W. So I contacted Lawrence who's also in SA, thinking all 230W 3401's are 1010W. However Lawrence confirmed the model he purchased last year was infact 4.1A 900W. We both have 230V 4.1A models however mines is 1010W and not 900W. Has Flex fitted more powerful motors to 2015 3401's?
 
The power P in watts (W) is equal to the voltage V in volts (V), times the current I in amps (A):

P(W) = V(V) × I(A) = 943 give or take
 
Yes and 110v X 7.5A= 825W,

943W >825W.

But that's not my point. My point is 1010W change from 900W ratings on the polisher and in the documentation.
 
But from your post, the current/amperage on the label hasn't changed. As Mayassa noted, this is math--you can't dissipate more power/wattage while the voltage and current remain the same (one of them has to go up). Sounds like maybe they just had an error on the label, which they corrected?

It may be that the 230V version has always dissipated a little more power (as evidenced by the current being more than half of the 115V version), but they never adjusted the wattage on the nameplate.

Unless Flex has changed a few "Universal Laws";
or you guys are now on a different line-voltage...

Then...at least mathematically speaking:
Those numbers don't figure-up.

Watts = Amps • Volts
Amps = Watts/Volts
Amps = 1010/230
Amps = 4.39

If:
4.39 Amps > 4.1 Amps...
Then (at least on paper):
It does look like they did.

One way or another, IMO:
The documentation and Spec. Plate needs attended to.

Can't be an error on both documentation and polisher:





 
I'm saying the error was listing the 230V version as 900W instead of 1010, and they've now corrected it.

Todd@Rupes was nice enough to respond and verify the Rupes changes, am hoping Flex can provide clarity to all us 110/230v users on what the situation is. Lawrence's 2014 230V states 900W my 2015 230V 1010W. I really would like to know if it was an error or were there changes and why. Also anyone have a 2015 110V version? If so, does it state 900W or 1010W as the changes might be on all 2015 versions regardless of voltage.

Even though it appears that you really
believe this to be true...FWIW:
I'm not such a trusting soul.

:idea:
Perhaps the Chinese embossing-tool wasn't able,
To stamp the "current info" on the 3401's label.

Wow, I guess this is all a big conspiracy, because my 3401 from 2008 doesn't even list wattage! It does say 120V 10.0 amps--so that's 1200 watts--beat that, mister!

It seems to me as you are under the impression I am competing of some sorts. Re-read the posts, I want to know of the discrepancies and variations. Why are there different power ratings on the same machine.
 
And I think you are over-thinking the whole thing. I was just at the Flex North America site, and depending where you look the US version draws 10 amps or 10.9. Where they list the power input as 10.9 amps, they list the power output as 590 watts...which means that at a possible 1308W input, they are dissipating 718 watts as heat.

I'm saying they aren't very consistent with their labeling/documentation/etc. which I attribute to sloppiness, different countries having different labeling requirements, new owners, etc., while you attribute it to some technical change.

Just the fact that mine calculates out to 1200 watts, do you think in 2008 they were making a more powerful machine and now less so? The fact that there are so many different numbers to me just says translation error, method of calculation changes (ambient temps?) etc.
 
Since the Flex is known for not bogging down, I don't think it really matters if it's 900 or 1010 watts. I doubt anyone would notice that small of a difference anyway. I also agree with what others have already said, there's no way two tools can have the same voltage and amp rating and different wattage ratings, just not possible.
 
Rupes states 500W regardless, I find it hard to believe that a polisher renowned for German precision would make a mess of power ratings. And no its no conspiracy as responses like that are the only sensationalism on this thread. I'd really appreciate responses from those informed rather than hear from the mines is bigger than yours types. The differing power ratings is no coincidence or fault from a label maker. Do you guys honestly think so low of Flex to insinuate they can't even get labels right?
 
Do you honestly think so low
of the following Scientists...

-Andre-Marie Ampere
-James Watt
-Alessandro Volta
-Georg Simon Ohm

...to insinuate that they couldn't even
get "electrical power figures" right?

I'm sorry you consider my input to be "sensationalism"; I would prefer to consider it rationalism. The Flex is sold internationally; you've got CE, UL, DIN, and who knows what other standards to adhere to. It may be that they each have different "rules" for specifying power, it may be that Flex's internal "rules" have changed over time--how else do you explain that my 2008 nameplate doesn't list wattage while yours does? I don't think they "forgot" to put the watts on mine, I just think they've changed the way they label the machines over time.

Besides, I think you are overthinking/overstating the importance of the nameplate ratings to the performance of the machine--the labeling requirements are so the user can make sure the circuit they are using isn't going to be overloaded--it's not some precise calculation of the performance or efficiency of the machine.
 
Would be nice to get some feedback though from a Flex technical representative. Right now we all assuming and all have opinions. Personally the machine is powerful enough and doesn't make any difference to me whether 900W or 1010W as either will get the job done. My curiosity however gets the better of me and I sometimes like it to be put to rest.

PS. Typing/Texting almost always gets misconstrued or misunderstood where if the person you were directing it at was infront of you they would infact understand it fully. A keyboard/pad doesn't have the ability to voice tone of statements.
 
Just an update, I was at the detailing shop where I purchased my Flex. We powered up both my 1010W and 900W polishers and the 1010W is more mechanical sounding if that makes any sense. They do sound and startup different. The store owner didn't know of the difference till I brought it up and also was certain its not just a label change. The 1010W was audibly louder.
