DC To AC Converter

Hello abe77

I trust you made an typing error when you stated: <"....60MHZ....">, and that the device nameplate really reads as 120V / 60Hz / 3W

I have checked the Specification on the weblink you quoted, and the Converter should be quite OK for the device, unless the device you intend is a motor, in which case you would need to check with the supplier.

Kind Regards....

Abe77,

of course, it isn't no problem about it ! There are many device like it .only the watt is different !

Regards

Inside the unit it probably has a transformer and bridge rectifier to produce DC for the circuitry....
However it may a switched mode power supply and several independant DC rails ... in which case you should close the unit quickly )
If you open it up (assuming you know what you are doing) you will be able to find the internal DC vlotage it requires (or the manufacturers may provide this information). You could wire DC into this point (e.g. the output side of the bridge rectifier.)

Pencil me in for all the usual safety warnings...

You don't say what DC supply you want to use? If it is a 12v battery , there are cheap 'inverters' you can buy to allow you to produce AC (120 or 240) from a car battery or similar.

Hello there, as somebody already pointed it out the name plate should be reading 60Hz and not 60MHz. May be you are also into IT industry where GHz is the talk of the time and MHz is history. This is not to insult you but imagine and AC supply with 60MHz frequency. It is as good as DC, but imagine the filtering, the noise induced etc., etc. Now the question is why would one do such a thing like use DC to power up a device which requires AC and AC supply is available in abundance. Whatever DC supply you have must be battery supply. How are you planning to charge them, which I guess will be rectifier/float charger etc., working on AC and what is the need to unnecessarily use inverter and lose some wattage in the conversion?

There are many instances when you want to convert DC into AC. For example... if you are using solar panels or a wind turbine to generate electricity for your house you generally are obtaining DC ... then you store it in a bank of batteries and then convert it to 120 VAC 60 Hz so that you can watch TV or power your PC =)

But any way... Does anyone have a good recommendation on what device to use for that purpose? I asked a friend who is an EE and he said to get a frecuency inverter... which kind is the best type of device for this application?

Why does a wind turbine generate DC? Is it not convenient to generate AC
