20BD034A3AYNACN0

The 20BD034A3AYNACN0 from Allen Bradley’s PowerFlex 700 series acts as an adjustable-frequency AC drive aimed at supporting industrial tasks. It is rated for 25 horsepower (non-derated) or 20 horsepower (derated), depending on the application. The unit operates with a 480 V AC input in a 3-phase configuration, ensuring compatibility with most motor systems.

It continuously delivers 34 A output current, effectively driving motors with a nominal voltage of 460 V. The system employs multiple control modes including V/Hz, sensorless vector, and vector, enabling versatility for various control strategies.

Overload protection is guaranteed with limits set at 110% for one minute and 150% for three seconds, allowing the drive to manage brief surges in load without failure. A transient-protected ride-through duration of at least 0.5 seconds maintains operational continuity during voltage fluctuations.

For integrated communication, this module features a ControlNet coax option which allows easy connection to networked systems. Additionally, the EMC filter consists of an integrated common-mode choke, which mitigates electrical noise and improves performance reliability.

The drive's DC bus voltage is specified at a nominal value of 648 V DC, supporting its efficient operation. Its adjustable pulse-width modulation (PWM) frequency can be modified between 2 kHz to 10 kHz, with a standard rating at 4 kHz, allowing for finer control of motor performance. Ultimately, the PowerFlex 700 series offers an extensive range of functionalities and protective measures, suited for demanding operating environments.
