220 to 110 Voltage converter

[Megawollt]

Hello from Russia.
I am electronics engineer and clock collector/seller.
I am developed and sell voltage converters for run American clocks in other counries
You can look it here and post questions in topic

Thanks for the information! These are very reasonably priced. I'm hoping to learn how these work for people.

Once I have bought clock from eBay and couldn`t make it run in Russia. I was forced to develop a converter by myself. After half year of experements I have made this and install it in some clocks.

It have precision generator on 60hz and divisor 220/110 the rest is my know-how

Also I will plan to make it in case(as shown on one photo), but US socket is impossible to buy in Russia. I wait it from China

This is good information, it will be slightly too big to incorporate it in the case for most clocks that I have, but still, as soon as you have them in a case, I will be more than happy to buy one or two so that I can use a nice US clock here (= Ireland) too!

[Megawollt]

Thanks. I think it is impossible to make smaller, but I wil try to do it in new version. I couldn`t install it inside my Sankyo 401 and made external box. When I will have parts, I will made some pcs in boxes

[flipoclock]

Do not worry, external box is fine for me...... I'm curious to see what the end result will be and what the total cost would be. I would definitively buy one or perhaps more when I like it.

You can see the result in post about sankyo 401. It will cost approximately 55-60$ with shipping

[flipoclock]

Do you have any idea when they will be available? I would like to buy one from you...

[Megawollt]

Two psc will be soon. For more I have no PCB because I am repairing many clocks and convert it to 220/50.
I will write, when it will be ready.

I ran into a problem. For differrent clocks I receive different results. Sometimes it heating and I install some resistors consistently to clock motor, but I don`t know how to make it universal.

Later I will draw schematic and post it here

[Megawollt]

I`v made 2 pcs. More is not expected in the near future

[Megawollt]

Price is 60$ with shipping.

[Johnevers]

Do you sell it as part of a Panasonic RC-6025/30?

[Megawollt]

I am not sell a parts
