GAC is the name of a series of bipolar chopper drives, suitable for driving two-phase stepping motors, with four, six or eight terminals.

GAC drives are realized in 250 x 100 x 56 mm format and are equipped with built-in power supply, screw-type terminals and brackets for mounting simplicity inside 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 reliable component, 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 of applications, 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 and motor, limiting the need for a forced ventilation while the standard input and output signals facilitate the interface with the most common control systems.
