The PowerFlex 700 series features the 20BD156A3AYNACA0, an advanced adjustable-frequency AC drive from Allen Bradley. Operable with a 480 V AC, 3-phase input, this drive can deliver robust performance, rated at 125 HP, and a continuous output current of 156 A. The system is designed for high efficiency, achieving an efficiency rating of 97.5% and a power factor of 0.98.

Control options for this drive include V/f, sensorless vector, and full vector, offering flexibility for a range of applications. Speed regulation is precise: around 0.1% of base speed without an encoder and approximately 0.5% with slip compensation, making it suitable for various operational conditions. The PWM frequency is set at 4 kHz, facilitating smooth motor control.

The drive is designed to handle significant overloads, capable of enduring conditions of up to 110% for one minute, and up to 150% for three seconds. The DC bus voltage typically hovers around 648 V DC and allows output voltages spanning from 0 to 460 V AC. The unit also includes critical voltage thresholds, with overvoltage limits near 810 V DC and undervoltage limits approximately at 305 V DC, enhancing its reliability and operational safety.
