Description
The VFD68 Variable Frequency Drive provides three-phase motor speed control in a variety of HVAC/R applications. The VFD68 drive is designed primarily for condenser fan speed control on HVAC and refrigeration condensing units, but can also be set up to control a variety of pumps, blowers, and fans.
The VFD68 drive accepts an input signal from P499 Electronic Pressure Transducer, or other devices that provide a 0 to 5 VDC, 0 to 10 VDC, or 4 to 20 mA signal.
The application-specific design of the VFD68 drive provides a simple interface, which makes the drive easy to understand and operate.
You can quickly and easily reconfigure the VFD68 drive to control variable speed pumps in cooling and heating applications, or to control variable speed supply fans in VAV applications. The VFD68 drive is an RS485, RTU-compliant ModBus® slave device and can be integrated into a ModBus network. Refer to the VFD68 Variable Frequency Drives Product Bulletin (LIT-12012068) for important product application information.
Features
- Selectable input types allows use with 0 to 5 VDC (ratiometric), 0 to 10 VDC, or 4 to 20 mA input signals from transducers, sensors, and controllers.
- High input signal selection of two similar inputs (230 or 460 volt models only) provides fan speed control of dual circuit condensing units, based on the highest pressure circuit.
- Compact design provides for easy and flexible installation.
- Three-phase, 230, 460, or 575 VAC models can control a wide variety of three-phase motors ranging up to 10hp.
- Simple and advanced end-user settings provide quick and simple application setup and operation, as well as advanced setup parameters for custom applications.
Applications
- The VFD68 drive 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 VFD68 drive allows the system to:
- maintain optimum condenser head pressure
- operate in low ambient temperature conditions down to -40ºC (-40ºF)
- reduce short-cycling, which occurs when using
- use On/Off fan controls
- maintain a more stable evaporator temperature
- operate more efficiently, reducing electricity cost. The VFD68 drive can also:
- help optimize compressor operation, reduce wear, and extend compressor life by stabilizing the condenser head pressures
- reduce motor repair and replacement costs by eliminating the condenser fan short-cycling
- extend refrigerated product life and provide more consistent comfort cooling by stabilizing evaporator temperaturesapplication setup and operation, as well as advanced setup parameters for custom applications.
