Johnson Controls VFD66BAA-1 Condenser Fan Speed Controls 1.8 Amp 460V 1Hp
The VFD66 Series Condenser Fan Speed Controls regulate the speed of three-phase condenser fan motors in refrigeration and Heating, Ventilating, and Air Conditioning (HVAC) systems by varying the frequency and voltage of the power supplied to the motor.
The VFD66 control accepts an input signal from the P35 Pressure Transducer, P499 Electronic Pressure Transducer, System 350™ pressure or temperature controls, or any other device that provides a 0-5 VDC or 0-10 VDC analog output signal.
The application-specific design of the VFD66 control provides a simple interface, which makes the control easy to understand and operate.
Features:
Isolated Input Circuitry - Permits application with 0-5 VDC or 0-10 VDC controllers, sensors, transducers, and Johnson Controls® System 350 controls
Simultaneous Acceptance of Two Similar Inputs - Allows use on dual refrigeration circuits cooled by a single fan
Compact Design - Provides installation ease and flexibility
Three-Phase, 208/230, or 400/460 VAC Models - Handle three-phase motors ranging up to 10.6 amperes at 208/230 VAC or 5.5 amperes at 400/460 VAC
Few End-User Settings - Provide fast and easy installation and setup
Application:
IMPORTANT: The VFD66 Series Condenser Fan Speed Controls are intended to control equipment under normal operating conditions. Where failure or malfunction of a VFD66 control could lead to an abnormal operating condition that could cause personal injury or damage to the equipment or other property, other devices, (limit or safety controls) or systems (alarm or supervisory) intended to warn of, or protect against, failure or malfunction of the VFD66 control must be incorporated into and maintained as part of the control system.
The VFD66 control accepts input signals from a variety of pressure transducers, temperature sensors, and low-voltage controllers to provide continuous response to changing condenser load conditions.
The VFD66 control allows the system to:
maintain optimum condenser head pressure in low ambient temperature conditions
eliminate short-cycling in low ambient temperatures or changing load conditions
match the condenser fan speed to the load on the condenser, which increases the efficiency of the refrigeration system. This can reduce electricity cost and help maintain a constant evaporator temperature.
The VFD66 control can also:
stabilize the condenser head pressures, which helps optimize compressor operation and can reduce wear and extend compressor life
eliminate the condenser fan short-cycling, which can reduce motor repair and replacement costs
stabilize evaporator temperatures, which can extend refrigerated product life and provide more consistent comfort cooling
