Power supply design

[Timvmax]

Can anybody help me with a drawing or some advice?
I am hoping to use 3 Viper 200's with 3 DC Brush SEM servos from a Bridgeport (145v, pulse Amps 32, stall torque 3.2Nm, 2500rpm)
I need to build a power supply as the servos I am using now are only 60v
I have seen a picture of a control box on a Bridgeport on the Viper drive website that looks like it has been done before, but it doesn't give any other details.
Any help would be greatly appreciated.
Tim.

If you visit a local electrical supplier you should be able to buy or order a 240/120 isolation transformer, i believe in the UK these are used as construction site isolators?
Buy the cheaper open frame style if possible.
You will need a large bridge rectifier and electrolytic capacitors.
These can be purchased at any electronic supplier.

Thanks Al,
I'd just searched and read some similar threads,
don't suppose you could tell me what spec bridge rectifier and electrolytic capacitors, or could point me to a calculator?

Ball park P.S. for all three motors, you will need a 1.5Kva transformer, 50amp bridge rectifier 350PIV, 33,000µf Capacitor 250vdc rating.

Is that why you're called Al the Man?
Many thanks, there's a beer for you here next time you're in the Uk :-)

Shropshire's a bit of a jump from Oxford, but you never know.
