Hi All, 

 


Sorry if it's a silly question but I have recently purchased US appliance from Amazon and didn't check to see what voltage it was.  I have had a look and it states:

 

 

 

Voltage: 110V/60Hz

 

Max. Power: 1800w

 

 

 

I have figured out I need to but a Step Down transfromer for it 2000w, but I am unsure on the 60Hz.  Would this ruin my new blender if it was running at 50Hz?  I was looking at something like the transformer in the link below?

Thanks!

NZ is 240V.  

 

 

 

Don't even try it.  I bought a Epson R2880 printer on Trademe off a USA guy.  The Epson printers unlike Canon are not worldwide  compatible.  I asked him, he said it is fine so it smoked and the capacitors gassed off.  I had to return it back to him but bought it scrap money, I got the replacement power supply circuit board off Aliexpress maybe a the Chinese factory scrap yards from unseallable printers so I repaired it myself.  

 

 

 

Can't help you with the exact transformer though.  Some transformers can be quite bulky and expensive that it might be better to just rebuy the appliance.  What I did with the printer was get a power board that specifically 240V.

I wouldn't try it either. If it was nothing but an AC motor, it would run, but at the wrong speed (as the AC motor speed is directly tied to the AC frequency - so, too slow in this case), but if there are internal electronics that aren't built with 240V in mind they may not be built with 50Hz in mind either.

I'm not sure what the other posters are concerned about. If the input to the device you want to run is 110V@60Hz, and the output of the step down transformer you've listed is 110V@60Hz, then I wouldn't expect any problem.

You just need a 230V to 110V step down transformer and it'll work fine.

 

BUT

 

Your device is 1800W - which means you need a step down transformer capable of supporting this high load. Last time I looked you'll probably pay around $300 for one of these which is suspect is a lot more than the cost of the blender.

A quick search shows $300 being a little optimistic - the best option I can find right now is this for $418

Transformers convert voltage not frequency. If you put 240V@50Hz into the step down transformer then you will get 110V@50Hz.

You have to watch the Amperage on NA devices. Without knowing exactly what this US appliance is I can only guess. So if I was to guess --- Most common house hold appliances drawing 1800W is probably 15 amps.

 

 

 

I wouldn't run it in my NZ home...even with a step down transformer. It will burn it out (the step down)...like our Canadian Treadmill did lol.

 

More edit - oh and like the Canadian skill saw that burned out the other 2000W step down transformer.  Good thing we brought 5 of them 2000W step downs. The Step down transformers were only $80 bucks -- not overly expensive vs NZ price for them.

Can't speak for the quality at that price, but the item the OP has linked to ticks all the requisite boxes;

 

Output voltage of 110V AC at 60Hz, max 3000W

It shouldn't matter in the real world though for something like a blender.

 

Lots of devices though are an issue though - In Japan they actually have both 50Hz and 60Hz 110V depending on where in the country you live so for things like fridges they either sell models with compressors designed for 50Hz or 60Hz or more commonly now compressors than can handle both.

Ohhh sorry missed that.

 

Wife uses our blender from NA fine (but I can't remember the specs on it....but an 1800W one- i'm not sure --would've checked the amps). Been using many NA devices from NA for 7 yrs on 50hz. Stereo Amp, Plasma TV, Kenwood Sub-woofer, Sewing Machine, Light fixtures with NZ bulbs,  Small Kitchen appliances. 900 watt Dalonge Mixer -- on step down transformers.

Depends on the blender. If it's a simple on/off AC motor it will run a bit slow, but otherwise OK. If it has electronic speed control then it will probably run at the right speed.

I have a question though...

 

If this American blender is 16.3 amp on 110v to get 1800Watts.

 

What is going to happen to how many watts here in NZ?

 

Cause at 10amps at 240v = 2400 watts (?) doesn't it?

 

Is it really going to be ok to run in NZ? Or will it just run at 7.5amps?

It runs at 16.3A at the blender, and 7.5A at the NZ outlet.
