Variable Frequency Drive (VFD)

The variable frequency drive system is an ideal choice for variable torque applications like centrifugal fans and pumps. Control your fan’s motor with this 500-horsepower VFD. The technology of this variable frequency drive will greatly improve the energy efficiency of your fan’s motor, and typically pays for itself in a matter of months. Even a very small reduction in speed will result in a large reduction of required horsepower. The variable frequency drive features:

• Factory-programmed and ready to run
• Designed for simplicity and clarity with the LCD operator display (and can be set to any of six languages)
• Easy programming of parameters, with free software to enhance parameter and date management
• Engineered for tough industrial environments; reliable with an MTFB of 28 years
• The variable frequency drive is provided in Normal Duty ratings with 110% overload capability
• V/f control mode, network communication options, and an array of input/output options available
• With an optional phase-shifting input transformer, it can be operated in 12-pulse rectification mode, reducing input current harmonic distortion
• Meets or exceeds power quality standards
