 Posted: Thu Feb 09, 2012 6:00 pm Post subject: Power transformers - where to buy? |
 |
|
| I have an espresso machine sent to me as a gift from home and it's 120v. I need a good power transformer. The last one I had would over heat like a beast and I never trusted it. Anyone know where I can get a good one? The only ones I can find in Korea seem to be 110v. Not sure if that would be problem. My machine also draws 1350watts, so I'll need a robust transformer. |

As long as the output voltages are 110-125VAC you are fine.
Look for one in the 2000-3000 kva range. The heavier it is to lift the better (bigger core and less likely to melt down).
Yongsan, under seon-in plaza, or the alley behind it (between there and the bank).
You can also look in the basement of the place between seon-in and nanjin arcade.
I have also seen heavy ones on the street side hardware stores at the nanjin arcade.
Last option would be to look downrange from one of the army bases. Anyone who lives off-post will have had to get them.

I read an article comparing 110v in Japan to 120v in the US. According to it, devices designed for 12v will mostly work fine with 110v. The only problems are lights, which are a little dimmer, and clocks, which often don't keep accurate time.
As for where to get it, I got mine, a nice heavy duty one for around 35,000 in Yongsan. In the iPark mall, same floor as the station, go to the back wall and head to the left. There is a shop there that sells transformers. |

The clock issue is due to differences in frequency 50hz vs 60hz.
Dimmer lights and slower coffee pots are due to reduced voltages 110VAC vs 120VAC.
The standard variance for line voltages in north America is ~10% (12VAC) hence the labels on most electrical devices reading 110-125VAC.

Did no one else think of trucks turning into robots when they read this thread?
Also isn't 120v the Korean standard? As TTOMPATZ said you should okaly dokaly |

umm..... no.
Standard line voltage in Korea is 220-250VAC (10% variance) and 60hz.
A step down transformer is need for those North American electric/electronic devices that are not dual voltage.
North America is 110-125 VAC (10% variance) and 60hz.

You can get 50hz converters here too...what's the big difference between 60 and 50? |

10 cycles per second in the sin wave.
clocks care, coffee pots don't.
If you are going to power a device from North America then get the 60hz model.

| thanks for this info. it looks like getting one that is 3kva is the way to go. |

Online you can try Gmarket. Look up 변압기.
You can also try Danawa which is a really good site aggregator . It's usually good for most electronics and other items. |

I'm glad I waited for your response. I feel I got a better one on Gmarket than I would've ended up with looking at the one at the Arrival store (somewhere else I was considering getting one from even with the apparent markup).
Thanks for the translation. That was the biggest help and made it super fast and easy to locate my options. |
