Johnson Controls VFD66FBE-1 VFD66 Condenser Fan Speed Control, NEMA 1 Enclosure With Alarm Output, 400 VAC 50 Hz, 208/230 VAC 60 Hz 5.5A - The VFD66 Series Condenser Fan Speed Controls are designed for speed control of 3-phase condenser fan motors in refrigeration and HVAC systems. The VFD66 controls regulate condenser fan motor speed by varying the frequency and voltage of the power supplied to the motor. The VFD66 controls use input signals from various devices to adjust fan speed and optimize condenser head pressure, especially during low ambient conditions. Condenser fan speed may be controlled by pressure or temperature. The VFD66 controls accept input signals from the P35 Pressure Transducer, P399 Electronic Pressure Transducer, System 350™ controls or any other device that provides a 0-5 VDC or 0-10 VDC analog input signal. The VFD66 controls have a simple interface, and are easy to understand and use. Minimal end-user setup is required because of the application-specific design.. Johnson Controls. Johnson Controls.
