Re: [CAD_CAM_EDM_DRO] BP Power supply

Hi Nathan,

The capacitors you want are the big round cans in the control cabinet,
with two screw terminals. Just check they are rated for at least 90V.
The capacitance and operating voltage are marked on the side. I used two
of them in my mill. Make sure you wire them up the right way. Either one
terminal will be marked with a +(+ve) or one will be marked with a big
line (-ve). If you wire one of these up the wrong way you can have a
pretty impressive explosion on your hands. I remeber having loads of fun
as a kid with a box of old caps and a lorry battery charger :-)

The bridge rectifiers are square plastic or metal blocks, with 4 spade
terminals sticking out of them. They are mounted on the heatsink that
sticks out the back of the control cabinet so you have to take nearly
everything apart to get to them. The terminals will be marked + - ~ ~.
the two ~ terminals go to the transformer, + and - are DC out.
