Allen Bradley 20BD027A0AYNANA0 PowerFlex 700 AC Drive 27 A at 20 Hp 20B

The 20BD027A0AYNANA0 drive is a PowerFlex 700 adjustable frequency AC drive designed and manufactured by Allen-Bradley. Salient features of PowerFlex 700 drives like this one include multiple motor control algorithms, flexible mounting and packaging, space-saving features, user-friendly tools for interfacing, and outstanding performance and control. The input of the 20BD027A0AYNANA0 drive is rated for 3-phase 480 Volts AC voltage. The drive output rating is at 60 Hertz input frequency is 27 Amps and 20 Horsepower. The input overvoltage and undervoltage protection are available on the drive and the corresponding tripping thresholds are 570 Volts AC and 280 Volts AC, respectively. The nominal bus voltage is 648 Volts DC. The drive bus is set to trip when the bus voltage exceeds 810 Volts DC and when it falls below 305 Volts DC. The rated efficiency for the drive is 97.5% at the rated output current and nominal input voltage. The displacement power factor for the drive is 0.98 across the complete speed range.

The features available as standard on the 20BD027A0AYNANA0 drive include the IGBT brake, standard controls, control I/O that support both 24 Volts AC and 24 Volts DC voltage, a CE filter, and a CM choke. Features not available on the 20BD027A0AYNANA0 drive include a brake resistor, an HMI, a communication slot, and a feedback encoder. However, multiple optional modules for HMI, communication, feedback, and internal brake resistors are available from Allen-Bradley and can be ordered according to the application requirements. The 20BD027A0AYNANA0 drive is available in a frame 2 enclosure with IP 20 protection rating which weighs 27.6 pounds and measures 342.5 x 222 x 200 millimeters. The rated velocity for the fan on the drive is 50 CFM and the drive produces 57 dB of sound (measured at a distance of 2 meters from the drive).
