GAC is the name of a series of bipolar chopper drives, suitable for driving two-phase stepping motors, withfour, six or eight terminals. GAC drives are realized in 250 x 100 x 56 mm format and are equipped with built-in power supply unit, screw-typeterminals and brackets for mounting simplicity inside industrial electrical cabinets. Due to this, they are particularly
suitable for stand-alone applications.R.T.A. experience, together with a careful design for these specific purposes, has led to a very reliablecomponent, easy to use and fit, ensuring optimum performance at competitive costs.The wide range of current/voltage values optimizes the use of GAC series drives in a large number ofapplications, with a great variety of stepping motors.Particular care has been dedicated also to obtain top performance and low power losses for both the card andmotor, limiting the need for a forced ventilation while the standard input and output signals facilitate the interface
with the most common control systems. 14
