Hello all,
I am trying to use a 220V DC motor to perform multiple actions that require different rotational speeds, so I need a voltage variator.
I was looking for something to work with Arduino, but I didn't find anything that could handle this voltages and intensities.
Do you have any recommendations?

What do You have for a Power-Supply ?
Line-Isolation ?
How much space ? (microscopic SMD, Aluminum-Box ?)
Does the Motor need to be reversible ?
Will You require the full ~800W / 240-Volts / ~3-Amps ?
