Converting a WARCO WM280V-F Lathe to 3 Phase Operation

摘要

The factory installed Warco Speed Display and Input Sensor Unit require 5vand 9v supplies. Ratherthan build a separate 12v power supply solely for the fan a new Power PCB was designed to provide all 3 power rails using the same PCB footprint as the now redundant Filter PCB, photo 21. The original insulated plate was used to mount the Power PCB to the component shelf.
