2-phase Micro-stepping driver 2L415B


2L415B is a high performance microstepping resolution driver that incorporates the most advanced technology in the world. It is suitable for driving any 2-phase and 4-phase hybrid step motors under 1.5A current. By using advanced bipolar constant-current chopping technique, it can output higher speed and more power than other drivers from the same motor. Its resolution function makes the motors run at high accuracy, less vibration and lower noise
