I need a electronic power supply product (AC to AC) that its output voltage is adjustable manually. Does anyone knows some some company/web /supplier in Europe? Thanks a lot.
Can you give some specifications about the required converter?
If you have the same frequency at the input and the output the simplest solution will be using an AUTOTRANSFORMER.If you want different frequencies at the input and output then you can use a rectifier followed by an inverter. Putting the detailed specifications helps you find the suitable product from the specialized company through the internet.
Thank you very much Abdelhalim Zekry, your information is very usefull, I have find the Isolation Transformers (Voltage Adjustable ) fits my requirements.
