400v main transformer

does anyone know where i can get one i need it for a coilgun experiment i live in the usa i need it as cheap as possible

Try to get one from a contactor control panel for 3 phase motors.
You may get one from a surplus electronics shop.

Often on 3 phase equipment a 400 (EU) or 480 (US) Volts supply is used for the motors while the contactor coils are supplied from a 24 V.ac transformer on the control panel.

Why make another thread?

Can't you also ask this in the other thread?

Are you asking for a transfromer or a power supply?

Can't you get hold of a 120V-270V transformer? This will give 380V when rectified.

thx for the advice the only thing is i dnt know where to find the transformer mentioned in the 2 reply ive only ebay so far s ill try other places thx though
