    Revised Flex 3401?

    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.

    I'm not such a trusting soul.


    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!
