20DD385A3ENNBNANE

The 20DD385A3ENNBNANE adjustable frequency AC drive from Allen-Bradley operates efficiently in three-phase systems at an input voltage of 480V AC. Designed for demanding applications, this model can handle a normal-duty current of up to 385 amps. As a member of the PowerFlex 700S series, it is tailored for precision in motor control.

This drive is encased in an IP20-rated enclosure, compliant with NEMA Type 1 protection standards, which provides adequate shielding from dust and incidental contact. Users can interact with the drive via a full numeric LCD, facilitating easy adjustments and monitoring of operational parameters.

A vital feature of this unit is the adjustable bus undervoltage trip, which allows users to set thresholds that suit their specific operational contexts. The drive does not include a braking mechanism but instead ensures efficient thermal management through a heat sink thermistor that is continuously monitored by an integrated microprocessor. This system triggers an overtemperature shutdown when necessary, ensuring equipment safety.

Operational resilience is built into the drive, with a logic control ride-thru lasting 0.25 seconds when the drive is not running. In addition, it can sustain a power ride-thru duration of 15 milliseconds at full load, providing crucial support during brief power interruptions. Overall, the 20DD385A3ENNBNANE is engineered to deliver reliable performance in industrial motor control applications.
