Question #: 14759

Question: Can I power the Mach3 USB interface 24V with a 48V power supply?

Current Solution

The Mach3 USB interface card uses 5V (powered from the computer's USB) and a 24v to power the inputs, outputs and spindle control

the mach3 usb interface can be found here:


But the mach3 usb does not absolutely need the 24V supply. The 24v supply is only needed if you will be using limit switches (I1-4), VFD controlled automatically and for use with the outputs (O1-4)

Additional Information:
The 36v 8.8 amp power supply we typically recommend is for powering the stepper motor drivers.
