US appliances: Is there an Electrical Engineer in the House?

OK, we've got a bunch of US kitchen appliances we are reluctant to just keep in the cupboard.

First, here are the electrical profiles for them (as far as we can tell):

Electric Grill: 120v / 60Hz / 1500W
Oven Toaster: 120v / 60Hz / 1090W
Water Boiler: 120v / 60Hz / 1500W
Coffee Maker: 120v / 60Hz / 1025W
Blender: 120v / 60Hz / 4.8amps (~528W)

So the question is, since most of these appliances don't need continuous plugging -- i.e. some will get less use (Grill / Boiler) some will get more (Coffee Maker):

Is there ONE single voltage transformer that will allow me to utilize all of the above appliances?

If so, what specifically should I ask for (and for bonus points, how much roughly am I looking to spend here)?

Many thanks in advance.

go with the highest power rating (wattage)

Actually, the best advice is "if it's got an electrical plug on it, and it doesn't have dual voltage built into it" don't bring it.

well, yeah, but op seemed intent on bringing them. or has them here already.

I love FT! Arrive without doing any homework. :-|

I wouldn't bother if I were you

Hi,

I'm new to the forum as I will be moving to Singapore soon (from Malaysia). But I am sort of a Electrical engineer so I'll throw in my two cents.

Anyway, SMB is right. Don't bother with it. Most of the appliance stated are very high wattage equipment. Even if you could find a transformer that met your requirements, the transformer itself would generate as much heat and sound as the equipment itself, if not more.

And you'll be using way more electricity which cost more money anyway so I would go ahead just buy local compatible appliances. The equipment listed is pretty generic anyway..


So bottom line is just because it can be done, doesn't mean that it should.

In Singapore the hz is 50 hz/60 hz hence it is switchable on AC . The Voltage is AC 230V.
In layman term, if the machinery is on 50 hz only and you are set up for 60 hz, it will slow the equipment dramatically vice versa. Hence in SG it is 50/60 hz.
You need to go for a step down VOLTAGE REGULATOR NOT STEP DOWN transformer AC 230 to AC 100>120 V. Rating should be at least 2000 W with voltage regulator if you are needing to use you a few simultaneously. Make sure the amps is 13 Amps on the stepdown and has several Two Flat Pin Output that is similar to US .
There are a few makes in SG and readily available. You have to shop around base on your budget

Many thanks to all the replies.

Mad Scientist (or anyone else) any recommendations as to where to find this item and roughly how much am I looking at? Obviously if its going to be over 100+, need to re-examine if its all worth the hassle...

Thanks again

you can get most of these for silly money in singapore if you are not bother about branded ones.

btw, the higher the wattage the step down transformer will take, the more expensive they are! and they are not very energy efficient!

not worth the hassle, give them to charity or some poor person so they can make a $ selling them on. Though I really doubt they are worth much to anyone in Singapore unless they have a the step down voltage.

Just to point out... all of the appliances are resistive heating devices except the blender, so being 50 Hz versus 6 Hz won't matter much... they just eat up electric juice to get hot.

The blender will work with approximately 15 percent slower speed... and might be subject to premature failure depending upon the nature of the motor in it... the current an electric motor draws is dependent upon a number of things including load and speed.

I agree with the rest. Unless you are talking about a $2000 expresso/latte machine, buy them here. A sufficiently decent transformer will be well north of S$100, will hum, be heavy, take up space, and will reduce your electrical efficiency.

OP

Look for this kind if you want to proceed. See link
