HGD 01
and 03
are a series of bipolar chopper drives, suitable for driving medium-low power two-phasestepping motors, with four, six or eight terminals. HGD 01
and 03
are realized in 70 x 70 mm format and are equipped with separated solder type connectorsfor logic signals and for power connections. They are designed for easy soldering and mounting on customer
realized PCB.This series of drives is intended to give a high torque and high speed alternative choice tot IC drives withhigher reliability.R.T.A. experience, together with a careful design for these specific purposes, has led to a high reliabilitycomponent, in spite of its very competitive cost.The wide range of voltages, current and resolution available ensures an easy use in any application.Standard input and output signals ease interfacing with the most commongly used control systems and ensurehigh noise immunity. 8
