*Haas machines are designed to operate on 220 VAC (200-240 VAC) power. An optional internal high-voltage transformer (380 - 480 VAC) is available for all models, except the Desktop Machines, CL-1, CM-1, and SR Series routers. This optional high-voltage internal transformer is not field installable; it must be ordered with the machine.

Haas machines destined for Europe and the UK are configured with an internal high-voltage non-isolated transformer to operate on 400 VAC, except the Desktop Machines, CL-1, CM-1, and SR Series routers.

ATTENTION! Optional high-performance spindles may have a higher power requirement than the standard spindle. However, if the spindle horsepower (kW) does not change, the power requirement remains the same. Verify the power requirement before running power for your machine.

† Air consumption on 40-taper DC Series machines may be higher, when Through-Tool Air Blast (TAB) is activated.
