I have recently obtained a Korean transformer of unclear specfications.

From the box photo (found these clean images on the net but the same as the unit I have) it appears to be a 240v - 220v transformer which operates at 2KVA.

I do need another 220v-120v step down transformer at home, but I don't think this will do the job. Many thanks for any assistance.

I can't help with the translation sorry,  if no one else comes forth what you could try at a bit of a push:

*take as clear and sharp a photo of the text as possible, maybe even scan it
*upload it to Google drive
*open it with Google docs and let the online OCR try and do its thing
*then tools->translate.




The first 5 days after the weekend are the hardest.

If you have an Android phone just fire up Google Translate, choose Korean as the input language and aim your camera at the transformer. Google will allow you to select and area of the image and translate on the fly. Might work in IOS also - don't know since I don't have one.

Honestly I tried that last night and it was a bit of a mess in terms of the translation. I was comparing the OCRed text with the actual text on the transformer and there were small errors everywhere, a dot to the right instead of to the left Korean syllables are very fine and detailed. Translation of this text ended up with a garbled mess of english with a few words here which made sense. Still no clear idea what this does though :(

You can go back to first principles and examine the connections. Then connect to the mains and measure the outputs.

It's better to use a variac where possible.

Where are you???

Cheers,
Chris

You have a higher understanding of electricity/transformers than i do, I'm ok with computers but sadly don't have the skills or knowledge to do what you suggest. I'm in Auckland.

If you get really stuck I can read (but not interpret) hangul so can give you the English text to put into a translator. But please try an app first as I will be very slow!

I would just guess that the knob is used to adjust the output voltage slightly up or down so that you can get a consistent output voltage (when the input changes).  But that is just a guess.

Have you tried plugging it in to see what the needle does? Are you concerned about plugging it in in case something goes wrong?

I got interested in this and decided to give it a try. I was able to clean up the images enough to get ocr recognition and I ran the text through Google translate. The result  is pretty garbled but it doesn't look like operating instructions or other useful information. The second image yielded the following:

Here is what I got from the fourth image:

Thank you. Trying to find a webpage with text specifications a manual would be even better. The OCR thing is really patchy.

Due to my lack of experience and skill, I haven't plugged this in, I guess I will test it out however as a last resort.

Thank you very much for your efforts. I managed to find a clear basic specification info on the internet and that OCRed ok. Have something to start with now.

I was able to find a clear image with specs which I was able to OCR 100% and translate.

(Product specification)

All persons Tel: JRH-2000
Rated output ː 2KVA
The first voltage range ː 190-240V
Rated primary voltage ː AC 220V
Rated frequency ː 60HZ
Rated secondary voltage ː AC220V
Breaker Capacityː 15A
Rated secondary current ː 9.1A
Hung Hung single issue ː way ticket lines
Product Size ː 190 * 265 * 125mm
Efficiency: Over 90%
Weight ː about 6.8KG
Manufacturer: Hanjin company General Electric

Interestingly I found there are three models, the JRD-2000 is a step-down transformer hence the "D", the JRU-2000 is a step-up transformer hence the "U". The JRH is a bit of an anomaly, perhaps it could be a step up/step down transformer or it could be something else.

If it's 220v in and 220 out then it is just an isolation transformer. I note your text says 60 hertz but on your image it says 50 hertz so these may not refer to the same transformer.
