voltage conversion trouble

[wwww]

We have bought an electronic device in Japan and tried to use it with a step-down voltage converter in Singapore.

So far nothing special. However, when doing so and plugging the voltage converter in, the plug overheated and fused with the biplug that we used. The biplug is no longer working.

The specs of the device are: 100 ~ 120 VAC, 50 or 60 Hz, 200w

The voltage converter specs are: 220-230V - 100 V

We normally use that converter for a Japanese fish grill, which works flawlessly.

Any ideas what went wrong?

Thank you

What kind of device?

I think you may need to be a bit more specific on what device you are trying to use? A better definition of "biplug" might help too.

Some devices rely on polarity for speed regulation or dimming, athough this is unlikely to be a problem in "home use" devices.

From what you wrote i would think immediatly that the step down convertor had a defect. Probably in the secondary 100V side. ( a fault in the primary would probably cause immediate short circuit or not work at all) Depending on the step down device ( short circuit protection) you could load up the output to overheating level without blowing a house fuse

Another good case for never leaving such step down devices plugged in and unattended !!

Good luck
