20AD027A0AYNANCN

The Allen Bradley 20AD027A0AYNANCN is a 480 Volts AC and 27 Amps rated drive. It is part of PowerFlex 70 AC drive family. Output specifications of the 20AD027A0AYNANCN at 480 Volts AC are 20 Horsepower and 27 Amps in normal duty mode. The 20AD027A0AYNANCN includes a brake IGBT and supports enhanced control (without safe torque off). A built-in HMI is not part of the 20AD027A0AYNANCN, however, optional HMI modules are available and can be ordered if required. The emission class for the drive is standard. Communication slot is not provided with the drive. The nominal bus voltage for the 20AD027A0AYNANCN around 480 Volts AC input is 648 Volts DC. Bus overvoltage, undervoltage shut off and undervoltage fault level is 810, 437 and 300 Volts AC respectively. The AC input overvoltage and undervoltage trip specifications are 570 and 280 Volts AC, respectively.

Only experienced and qualified personnel should be involved in the installation and maintenance of the 20AD027A0AYNANCN. Before any work is performed on the drive, it must be ensured that the voltage on the bus capacitors has discharged. The DC bus voltage can be measured at the +DC terminal of the power terminal block and –DC test point.  This voltage must be allowed to reach zero before the commencement of maintenance activities. The D-frame 20AD027A0AYNANCN weighs approximately 9.3 kilograms. Its IP20 rated enclosure measures 350 x 180 x 220 millimeters. The recommended temperature range for drive storage and drive operation is -40 to 158 and 32 to 122 degrees Fahrenheit respectively.
