The DM4050tm microstepping driver is a 40 volt, 5 Amp per phase stepper motor driver providing 400 watts of power in a compact package. The DM4050tm is suitable to drive NEMA size 23 and 34 motors typically used in engravers, wood routers and many types of automated machinery. The DM4050 driver can be used in conjunction with our OptiStep Plus, MN100 or MN400 motion controllers or with any controller capable of producing TTL compatible step and direction signals.
