20AD027A0NYNACNN

The Allen Bradley 20AD027A0NYNACNN is an adjustable frequency AC drive which is part of the PowerFlex 70 drive family. The 20AD027A0NYNACNN is designed for three-phase (six pulses) 480 Volts AC input. The normal duty output rating of the drive at 480 volts AC (50 Hertz) is 27 Amps and 11 kilowatts (20 Horsepower). Its single phase input voltage provides 50% of the rated output current. This module’s input overvoltage and undervoltage trip specifications are 690 and 345 Volts AC and the nominal bus voltage is 648 Volts DC whereas the bus overvoltage trip and undervoltage shut-off specifications are 810 and 437 Volts DC.

The 20AD027A0NYNACNN does not include an HMI. A brake IGBT is provided with the drive. An internal brake resistor is not included while a ControlNet communications port is included; this port is also compatible with coaxial cable. A standard control module is included with the drive.  Care should be taken to avoid installing the 20AD027A0NYNACNN in an environment which contains dust or corrosive gas or vapors. The 20AD027A0NYNACNN is a frame D drive and is available in a panel mount IP 20 rated NEMA type 1 enclosure. Dimensions of the drive enclosure are 13.78 x 8.66 x 7.08 inches. The recommended maximum ambient air temperature which does not lead to drive derating is from 0 to 50 degrees Celsius. The drive storage temperature range is from -40 to 70 degrees Celsius. The total power dissipated as heat during drive operation is 475.8 Watts and the weight of the drive is 9.25 kilograms.
