I'm selling a bunch of parts that came out of my BOSS3 control, including this power supply (see image).

Does anyone know the voltage/amperage rating for this power supply? What input voltage does it use? The reason I ask is that I want to pass this info on to a potential ebay buyer. One more question - is this the power supply for the stepper motors, or the one for the BOSS3 computer?

That is called the "axis drive chassis". The small transformer (T7) is the +24V power supply transformer and capacitor (C2 @ 3500mF). The 6 silver caps (5500mF) are for the +56V power supply, but I am not too sure where the 56V transformer (T6) is located. Wire numbers 34 and 35 attach the output of T6 to the bridge rectifier (BR1).

Careful as the large heatsink there has 4 bridge rectifiers on it. One for the 56 V supply and 3 for the drive power supply which is what the 56 V caps are for.
Yes, it is confusing. Look at the print I loaded up in the previous trend. The T2 transformer (3 phase) puts out between 54 to 63 VAC for the drives.

Thanks guys, that helps a lot!
