RE: [CAD_CAM_EDM_DRO] Failed Power Supply
The biggest problems with those drives has been that the big coil vibrates loose in shipping. The other problem is when they fail they generally jump the voltage up to 65V which fries the G540.
Not sure what could have caused yours to fail. I use a different brand for the control units that I build for a machine tool company. They run 4 3.5A motors on them with no problem. I have worked with my supplier of those type of power supplies and they have made improvements to eliminate the coil coming loose.

This is a photo of one of the 48V 7.3A supplies imported by Keling. I was
driving a 6A Size 34 motor with it through a Gecko. Clearly it wasn't up
to the task as you can see from the black coil that should be golden brown
and the brown on the undersize of the cover. I think a linear supply will
be the replacement. Or an oversized switcher with a big capacitor by the
Gecko.

Anyone else had problems with these supplies?
