TH2608M/TH2608M-H is a constant torque high performance driver with microstep, voltage range from AC18-80V single power input. It can match two phase hybrid step motors whose rated current under 6.0A flange size range from 57、~86mm. Owe to bipolar constant current chopper control of the driver circuit, the motor can run smoothly and hardly has any noise.Rising the voltage can greatly improve high speed performance and output torque of the motor. Once the pulse stops for 100ms,the phase current will automatically cut by half, which can reduce chances of overheat. Users can operate the driver with microstep in low speed occasion.The upmost microstep can be set to 200.
