SG Series Variable Frequency Drives<\/h2>\n\nBenshaw SG Series Variable Frequency Drives are microprocessor based, offering sensorless vector control for AC induction motors. Our SG Series drives take advantage of a powerful 32-bit microprocessor control and next generation IGBT power switching technology to provide high performance electronic motor control.<\/p>\n<\/blockquote>\n
SG Series Variable Frequency Drives<\/strong> support applications ranging from 7.5 HP to 40 HP (@ 230 volts), 7.5 HP to 700 HP (@ 460 volts) and 7.5 HP to 400 HP (@ 600 volts). All drives in the SG series feature an intuitive LCD display\/keypad that displays information in plain English \u2014 with no special codes to look up \u2014 making drive setup, operation and fault diagnosis as simple and straightforward as possible.<\/p>\nSG Series Variable Frequency Drives are well-suited for basic fan\/pump applications, but are also used in more demanding industrial speed control applications.
