Pro Cabin 67-z Voltage

[kyuseok]

Hello, I hope you are having a great day.
Fortunately, I recently got a chance to buy this affordable 6x7 slide projector. However, what I am concerned about its voltage.

I have acquired Japanese version which operates at 100~120V AC, however I live in South Korea where 220V AC is fed to every households.

Manual specifies that "100V-120V or 220-240V" however brochure specifies just "110-240V".
So, do I need a transformer or I just have to change bulb to 220V one and just plug it in an outlet right away?

Any input will be welcomed. Thanks a lot!

I have never used this projector. There's a free copy of the manual here BTW: http://www.troeszter.net/Download/CabinManual.pdf but it doesn't have more detailed specifications. It does show that the recommended fuse is different for the 220 V version (1.5A instead of 3A).

Personally, I would not plug it into 220 V unless you can inspect the inside and determine that it has no voltage sensitive components. Modern power supplies such as laptop power bricks use a switch-mode power supply, which is how they handle both 110 and 220 V. I doubt the Pro Cabin uses an SMPS. It surely has a bulb and a fuse, both of which you would need to change for the 220 V version. It also has a fan, and there's a good chance the fan is sensitive to the input voltage and would burn out on the higher voltage.

Thanks a lot! I will use it with step down transformer as long as possible!

Things are much more complicated ...

Basically 3 things are to contemplate about !

-) Voltage

-) Current

-) Frequency


With an incendescant lamp first thing to handle is the voltage. Which would be not an issue as mains-voltage lamps typically came in different voltage ratings.
Furthermore one can assume that a circuit apt for 110V still is apt for 220 (a electrical engineer may say different though)
Next thing is the current. You not necessarily can go from 220V to 110V as then at same lamp-wattage curreent is doubled and this could be too much for the wiring. (With low wattage mains lamps and standard cables this may be no issue as there maay be a reserve at the cable.) But you woul double voltage and thus reduce the current to about half.
Mains frquency is no issue with incandescant lamps.


Next thing to consider is the fan.
Here it becomes more complicated. Chances are that its coil blows at 220V.
Mains frequency is also an issue, both for motor frequency (in this case likely negligable) and for motor saturation (only if frequency is risen).

Thank you for your warmest welcome! I definitely don't want to blow the fan up I am planning to buy a second-hand 1000W step down transformer tomorrow. Have a nice day!
