Voltage Question for "The Speedster" variable fan speed controller

Hi All,

I recently purchased the "Speedster" variable fan speed controller from the states and want to use it here in Asia but the voltage is different.

The Speedster has an input voltage of 120V while the voltage in Asia is 220V.

My question is, my current 6" exhaust fan is a 220V so would I need to use 1 or 2 voltage converters in order to use the speedster? Do I use the converter at the output of The Speedster or at the input of the Speedster? Or do I need to use 2 converters, one for the input (exhaust fan to the Speedster) and one for the input (from the Speedster to the electrical outlet?)

Its kinda hard for me to explain but I hope some of you understand what my question is and can offer some advice by looking at the diagram I drew below!

Thanks!

I'm no electrician but I have worked with alot of DIY projects and am quite electrical/mechanical minded myself but I would say if the speed controller is 120v and the fan is 220v you would need:
220v Wall Socket > 220-120v Converter > 120v Speed Controller > 120-220v Converter > 220v Fan

Notice the 2 converters are different as one is dropping the voltage, then the other is returning it back to the fan's voltage.

However, these converters may not function properly if the voltages have been played around with by the speed controller, and they may also cause a hum from the fan too? Someone correct me if I am wrong about the voltage change problem and fan hum.

if u make a strain ...call it the amish fucker

here order it quick a 220 volt controler from ebay .............i have nothing to do with them i just rem seeing the controller in that volt when i was shoping so i posted for u ..........here let me see if i can amazon it for yah yah i looked i did not see anything but this is usa searching

if the plug does not match your sockets u can strip it off and add one for that area
