NOTE: Electronic circuitry built into the speed control supplies a constant 90V DC output to the motor regardless of the input current from 100VAC to 240VAC, 50 or 60 Hz, so Sherline machines can be plugged in and used in any country in the world without a transformer as long as you have the correct wall plug converter..
USE WITH AN INVERTER: This motor and speed control can be used with an inverter that produces a sine wave. It cannot be used with an inverter that produces a square wave.
