Hello everyone!

Po 104W

torque 253 oz-in

What kind of controller and power supply is needed for get best of this stepper? Is it possible to make at home such controller? I know that is good to have multiple voltage power supply, so I guess I must have around 140V power supply. But I don't know any driver chips similar l298 that can handle that much voltage.



Any advice?



Boris
