Driver Features

1,Low noise and runs smoothly

2,High performance, low price

3,Provides 12/8 kinds of micro step selection,upmost micro step can be set to 200 x,enhance resolution

4,Special control circuit, greatly reduce noise, increase steadiness

5,Upmost response frequence amounts to 200Kpps

6, Once the pulse stops for 100ms,the phase current will automatically cut by half

7,Bipolar constant current chopper control

8,Photocoupler isolated input/output

9,Drive current range from 0.1A/phase~4.0A/phase

10, can match two phase hybrid step motors whose rated current under 4.0A11,Single power input, voltage range from DC12-40V

12,Protection circuit,Overheat protection. Over current, under voltage protection

13,Small in size.compact driver, its dimension is only 25x136x92mm3.
