How To Use A Step Up/Down Transformer

- Step up/down transformers allow you to step up 110/115/120 volts AC to 220/230/240 volts AC or step down 220/230/240 volts AC to 110/115/120 volts AC.
This is very helpful when you need to use a 220/230/240 device in the U.S. and you don’t have a 220/230/240 wall receptacle available or don’t have the ability to have a licensed electrician install one for you.
Since stepping transformers are made to be used internationally, most come with a Schuko plug which is not compatible with receptacles (outlets) available in the U.S.
To use a stepping transformer in the U.S. to step up the voltage from 110/115/120 volts AC to 220/230/240 volts AC, you must use an adapter that converts the Schuko plug into a standard U.S. NEMA 5-15P (plug). Secondly, depending on the model of stepping transformer used, you typically need to set the voltage switch to 110 volts. The default setting is typically 220 volts and must be changed before plugging the transformer in. DO NOT CHANGE THE VOLTAGE SWITCH WITH THE TRANSFORMER PLUGGED IN.
The adapter used in this video is available at the below links.

Why is the video incomplete? how do you step down from 220 to 110/
Base on this video, I guess it's okay / safe to plug a transformer into a power strip as opposed to directly to mains power / wall socket.(as long as the power strip can handle the load)
120 volts from power strip and typically 15 amp breakers so it would depend how many amps ur trasnformer draws
Im assuming if you plug it, wall>transformer>extension, the entire extension strip outlet would be what the output of the transformer is?
What if I plug it the way it is in the video, but the wall is 220v, so the transformer plugged into extension is stepdown to a 110v output and i use device for the one plugger into the transformer a 110v device, but the other outlet of the extension to a 220v?
I have a 1.5hp air conditioner and it’s acting up because of low current in Nigeria. Can I get this to push up the voltage?
Good day. If my device says 100-220v, does that mean I don’t need a transformer and would it affect my device if I use a transformer anyway?
One of the cables has come lose from my very primitive Danbury electronics 120-220 current transformer. I need help in connecting it back. Any help appreciated!
Does it need to go into the wall power outlet or would it work fine on a power brick?
Thanks for the video.
Can this be used with an industrial machine
Hi how many watt can you pull out of the transformer
Can I plug my fender rumble 25 U.S in this?
I recommend cheap multimeter when testing. The switch can be put wrong way round. I plugged mine and I had 240 in 450 out.switch in wrong position. A multi tap transformer would have better. As I like using isolation transformer for electronics. But earth is connected on this brand.
hi, is it normal for the transformer to vibrate when plugged into the wall?
I think it’s normal because I recently bought a Korg X5D from the United Kingdom. The seller gave me a Uk Adapter and he told me that I need to buy a US adapter and use the Seven Star converter. I bought it today and when I set the voltage to 110v, it vibrates when plugged into the wall. I think it’s normal.
Hi what is the size and Amp rating of the fuse
Can you run a small stick welder off of it
Do you know if it has a toroidal transformer on the inside? Can't seem to find any info on this. Thanks
It's obviously an EI core transformer. Why?
E I transformer.
Is it normal for it to get warm when using with electronics devices?
If its getting warm then you may need a bigger wattage
@@dxlink really? My uncle said it should be double the appliance wattage. My US bought turntable is 110v and 19watts, i used my uncle's transformer temporarily which was 1,500watts until my 50watt transformer gets here. My uncle's 1500watt transformer would get hot though
Hello, super informative. Just wondering where hertz comes to play in all of this. If my hair dryer is 60 hz what does this mean. Would any step up do???
Herts remains the same a step up see saw of volts double amps reduce in half or visa versa step down amps double volts reduce in half. That's to say sign wave hight volts increase/decrease but Hertz frequency wave to wave peak distance is same distance/time
Does this thing have actual ground connection?
Most likely through the plug socket
That particular design of plug seems to be one called "hybrid E/F". It is designed to be grounded via grounding fingers at the edge of the socket recess of a Type F socket, or the protruding ground pin of a Type E socket. Unfortunately, the adapter shown in the video does not appear to provide grounding through either of these methods, so the metal case of the transformer and the output socket ground are probably left floating.
But this is just due to a poor choice of adapter; the transformer itself looks like it's designed to be grounded.
Could you use this for a UK coffee machine that uses 240 in Canada on 110?
yes but you have to see the number of powers watts must be more then 1500 watts and this one is 2000 watts so it will work
Install 220V US horizontal flat pin outlet, and use World to US 220V universal plug adapter.
I am the new kid in the block if you zoom closer for 110v when testing I would know where you put the test needle at.
Does anyone knows if the 220v comes on the hot wire Europe style , or comes out like in the U.S. with two hots and a ground?
Ok still don't have a clue what you are talking about I have a guitar amplifier that is 230 volts I live in the USA I need to plug in to 120 volts how do you do that? Whit this step down converter
Switch over in step down mode. Being from. China I have a small version and checked the voltage to make sure in step down I was getting 110 volts. I have an American dewalt cordless battery charger. I live in Australia with 240 volts at the wall. Actually 235 volts when measured.
@@dragan3290 How many hours to charge?
@@likaqoqashvili9851 it should still charge at standard rate. If 1 hour charger? It Will take 1 hour. Higher voltage = less current. Lower voltage= higher current. Mine was charging at 3 amps at 240 volts approximately. 720 watts. I hope I answered ok? Cheers.
@@dragan3290 thank you ❤️
@@likaqoqashvili9851 your welcome. I'm glad I could help! Cheers
Could you use this to power a 240 amp table saw, U.S.?
240 amp??? No way.
I bought the exact same transformer a few days ago. For some reason I can't plug my appliance into the transformer. It's seems like there's something inside the outlet of the transformer disturbing. I though there is a button or something but couldn't find one. Any idea what am I missing?? Thank you!
You probably are plugging a two prong plug in and the receptacle needs 3 prongs (ie with a ground or earth prong) to release a safety block. Change your 2 prong plug to a 3 prong plug even if there is no ground wire to attach and it will plug in releasing that safety block
3:17 daisy chaining
Dangerously connected through inappropriate non earthed/grounded adapter
how many amps can you pull from that sort of thing,
Use Ohm's law
If you're in the US and you're only going to get 15 amps at 120 volts or 7.5 amps at 220 volts.
1500 W Max maybe 1800 if you're lucky?
That's how its used in us. So how it work in the USSR?
You wouldn't.
Since their outlets consist of 220v, there would be no need for a step-up transformer.
Otherwise, you just flip the switch the opposite way.
It no work in USSR. USSR go away no come back.
Why do they label everything and wind the core for 115 volts when they haven't used 115 volts in decades?
Everything is 120 volts, maybe even 125 volts now.
Like with a variac, instead of cranking it up to 115 volts at 100% you can crank it up to 149 volts at 100%.
can i use this with air condition?
My amplifier is 230 volts 50hz and 20watts is this ok to use for my amplifier?
Yes it definitely will run it. But it's not 2000 watt but 1500 watt transformer. Only thing you need to find out is American 60 Hz comparing to 50 Hz, not going to damage amplifier.
Can anyone help me how to connection input wire this transformer..
Ok I get it know
Ughhhh
