20DD460ACENNBNASE

The Allen-Bradley 20DD460ACENNBNASE adjustable frequency AC drive is engineered for efficiency in demanding industrial environments. Operating at a voltage of 480 volts AC, this drive supports three-phase systems and is capable of managing an input current of 460 amps. The robust design is housed in a compact IP20 enclosure that adheres to NEMA Type 1 standards, ensuring reliable operation in typical settings.

A full numeric LCD that mounts on the door serves as the human-machine interface, facilitating easy adjustments and monitoring by the user. To assist with setup, the product includes a quick start guide. Notably, the drive does not feature a braking system, leading to a simplified configuration. However, it does include an adjustable bus undervoltage trip to guard against potential power issues.

Thermal management is crucial in maintaining performance, which is why the heat sink thermistor is actively monitored by a microprocessor to preempt overheating situations. Furthermore, this model provides a logic control ride-thru of 0.25 seconds when the drive is not running, ensuring operational consistency during brief power fluctuations. For more extensive power interruptions, the drive supports a power ride-thru period of 15 milliseconds under full load conditions, providing an additional layer of reliability in critical applications.
