RTA’s NDC series features mid-power bipolar ministep drives with STEP&DIRECTION interface (pulse train). It is characterized by a medium power range (up to 75 Vdc, 6 Amps), small dimensions and great usage flexibility. All models are equipped with Chopper systems featuring high performance Mosfet power stage, microstepping up to 4.000 step/rev. and protections for short circuit, overvoltage and temperature. The wide range of power supply and current levels have made this series a real best seller among RTA’s products.
