Looking to bring some speakers from UK to canada.

[Querkle]

Hello, while in the UK i have aquired a pair of KRK V6S4 for £250, which is a very good price as they normally go upwards of £400 each.

i have tried to sell them but it seems second hand no one is willing to pay me even £400 for the pair, so i think it makes sense to bring them with me.

on the back they say 100-240v and they list 2 different fuses for different voltages, ive looked and i can order the fuses needed easily

im of the understanding that if i simply switch the fuse it should work, but the fuse cover sais "use only with 250v fuse", which is quite contradictory to the other labelling

posting here to make sure im not crazy and that a simple fuse switch should work.

If you halve the voltage, you double the current, so it makes sense that the 110V fusing should be twice the 220V fusing.
The power supply is presumably a Switch-Mode supply that can work at anything from 100-240V, so you just need to have the appropriate fuse.

thanks, thats exactly what i thought, however the bit saying use only with 250v fuse on the fuse itself is the only worrying bit, perhaps that entire socket needs to be replaced?

edit:

well if i am able to get them back to canada and they work on 120v i may send one to amir for testing

I don't think that's the case here,if it was they wouldn't have marked the 240V box.
It maybe can work with both conditions AFTER an external or internal switch or connection is in place.

No need to replace the socket. Most equipment these days uses 20mm fuses, which as far as I know are rated at 250V, although 1 1/4" fuses are more common in North America, but even those (I think!) are rated at 250V -at least, I've not come across any which weren't.

It seems to me that the 240v box was marked because it's been fitted with a 3.15Amp fuse, not because it can't work over the full range.

I suppose the only real question is Slow-blow or Quick-blow? I'm guessing slow, given that it's input power protection.

I couldn't find this exact model but Rokit 5 manual says that there are completely different models for the various continental systems.
It's better to confirm it before plug it.

It says slow on the label, that's what the T in T3.15A indicates. A Fast blow fuse would be labelled as F3.15A

id say KRK is likely to give an incompetant answer even about there own products.

this was exactly what i was thinking and hoping, so i guess i will just have to try and find out, i guess if something else does need to be changed i can hopefully do that, but i cant imagine what it would be.

What's the voltage in Canada?

 

[JayGilb]

Almost all line fuses for consumer electronics are rated at 250VAC. I'm guessing it's because that is the maximum voltage found in any country and it would allow even an underrated fuse (amperage wise) to work anywhere.

 

[Querkle]

What's the voltage in Canada?

100-120 or 110-120

 

[Sokel]

100-120 or 110-120

Then it's a gamble plugging a 240V device in 120V voltage plug.
Ask KRK for that!

It uses an universal power supply and will work in a 240 and 120 volt power grid.
Some electronics have a little (usually) red switch that allows the user to switch between 120 and 240, but a lot of modern electronics are designed to be used in either voltage.

I know of them,mine uses PFC and is universal.
I was concerned by the fact that they are marked as 240V version but as long as people here are sure they are universal then it's fine by me.

Yea, I understand your concern, but I believe the 240 marking is indicating the currently installed fuse size.
