York S1-6109904 2HP Programmable Variable Frequency Drive 240V/3PH

The York S1-6109904 2HP Programmable VFD is an electrical unit intended for varying the speed and torque of three-phase AC motors. It does this by rectifying the fixed frequency AC power from the utility grid to variable frequency AC power. The output frequency of the VFD is also made variable hence the motor can be made to run at the most optimum speed of performance and energy efficient. In HVAC applications, this VFD is suitable for controlling fans, pumps, and compressors that are likely to be used. For instance, in chillers and air handling units, the VFD will act as a fan speed controller, thereby contributing to remarkable energy saving.
