NDC 94 model is fitted into a metallic box of (110 x 108 x 34 mm). It is equipped with plug-in connectors, separated for power and logic sections. It is able to drive motors up to 2 Amps nominal current and it is the perfect choice for mid-power applications with small and mid-size stepper motors.
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, 2 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 the current levels have made this series a real best seller among RTA’s products.
