For CNC, EDM, Computers, Lasers, and other voltage sensitive equipment. 3-Phase, 3-wire Delta output voltage is internally regulated (balance ±5%). Does not incorporate extraneous capacitor/relay-switching devices which can damage CNC control components.
“A CNC is the machine-tool equivalent of buying a Farrari. You wouldn’t think of draining the gas out of a farm tractor to put into a highly-tuned sports car, would you? Electricity is fuel. You wouldn’t think people would shop around for a home-made or non-CNC rated phase converter to run their new “Ferrari” but we witness this frequently. Those who do so will only frustrate production schedules and put their machine warranty at risk.”
This is a used Smith Electric Motorworks GWM DIGI 324 18 HP Rotary Phase Converter for CNC machines. It was used in a one man shop to operate a Haas CNC machine near Spartanburg, South Carolina.
