The DVS278 is full digital 2 phase stepper driver based on DSP control. The drive voltage of which is from 24V to 80VDC. It is designed for use with the 2 phase hybrid stepper motor of all kinds with 57mm to 86mm outside diameter, regulated phase current from 2.0A to 7.2A. The highest micro step is 40000ppr. It is widely used in small size numerical control devices such as curving machine, packing machine, CNC and etc.
