Variable-frequency ac drives

VariFlex Series ac drives are suitable for most industrial motor control applications. Compact units handle general-purpose, three-phase motor-control applications from 1/3-5 hp and come in three frame sizes (A, B, and C), covering bus voltages from 180-528 V ac. They universally accept single- and three-phase supply voltages. Limited dimensions (widths less than 3 in.) minimize required space within the electrical enclosure. Modbus capabilities are standard. Programming can be cloned from one drive to another using the company’s SmartStick custom memory tool. Ten common drive parameters listed on the front cover are sufficient for most applications; a remote keypad is also available. www.gavazzionline.com Carlo Gavazzi
