20DD300A3NNNNNBUE

The 20DD300A3NNNNNBUE from the Allen-Bradley PowerFlex 700S range is an adjustable frequency AC drive designed for optimal performance in industrial applications. This device operates on a voltage of 480V AC and is configured for three-phase systems. With an impressive normal-duty current rating of 300 Amps, it is well-suited for demanding motor control tasks.

The drive is housed within an enclosure rated IP20, which adheres to NEMA Type 1 standards and provides basic protection against dust and contact. It features a full numeric LCD that allows operators to monitor and adjust settings as necessary. While this model does not incorporate a braking system, it includes an adjustable bus undervoltage trip that allows users to customize the operational parameters to enhance safety.

Thermal management is vital for reliability, and as such, the heat sink thermistor is continuously monitored by a microprocessor that activates an overtemperature trip if conditions become critical. For operational stability, the drive provides a logic control ride-thru capability of 0.25 seconds, preventing disruptions during short power interruptions while not actively running. Furthermore, it supports a power ride-thru capability of 15 milliseconds at full load, ensuring that motor operations continue uninterrupted even during transient conditions. The 20DD300A3NNNNNBUE exemplifies durability and performance in adjustable frequency drive technology.
