Open Enclosure Drives
An open enclosure drive is a type of variable frequency drive (also known as a VFD) with accessible internal electronics. A variable frequency drive is used in an electromechanical drive system to make the speed and torque of AC motors variable for purposes of efficiency, safety and performance. It makes motor speed adjustable by varying the output of frequency and voltage that it feeds the motor. Products vary by the type of protection they provide Brands include Schneider Electric and others. Products vary by input / output phase, output voltage, adjustable acceleration / deceleration time, type of protection it provides, applications and other considerations. Available accessories include various cards, keypads, mounting kits, cables and more.
