20DD500ACENNBEANE

The 20DD500ACENNBEANE AC drive from Allen-Bradley is structured for adjustable frequency operations. It is designed for three-phase systems and operates efficiently at a voltage level of 480V AC. The unit is rated for a maximum current of 500 amps, accommodating extensive power needs in various industrial applications. Its construction adheres to IP20 and NEMA Type 1 ratings, ensuring adequate protection for indoor use.

Equipped with a full numeric LCD for the human-machine interface, this model allows for simple door mounting and easy access to settings and diagnostics. A quick start guide is included, providing essential details for installation and setup. Notably, this drive does not incorporate a braking system, which should be considered during design integration.

The adjustable bus undervoltage trip feature adds safety by enabling customization according to operational demands. Thermal management is addressed through a heat sink thermistor, which is actively monitored by a microprocessor to prevent overheating through an overtemp trip. Furthermore, the logic control ride-thru capability lasts 0.25 seconds when the drive is not actively running, which helps maintain stability against short power interruptions. Additionally, it can sustain power ride-thru for 15 milliseconds at full load, ensuring continuity during brief voltage fluctuations. Overall, the 20DD500ACENNBEANE is optimal for high-performance applications requiring reliable drive control.
