Re: [CAD_CAM_EDM_DRO] BP Power supply

Hi Nathan,
In my machine the transformer was in the top left of the cabinet. It is
the one that supplies the auxiliary 110V. You don't need the big 3 phase
one in the middle or the three chokes below it. The 3 phase transformer
is easy to recognise because it has 3 legs, each one having it's own
windings.


Tha transformer has a diagram on it giving the connections for different
power supply voltages. You want to wire it up for twice your actual
supply voltage. This will give 55V out instead of 110V out.
