20DD385ACENNBRNNN

The 20DD385ACENNBRNNN is part of the PowerFlex 700S series from Allen-Bradley, a subsidiary of Rockwell Automation. This adjustable-frequency AC drive is engineered for three-phase operations and functions effectively at a voltage level of 480V AC. It accommodates an impressive normal-duty current of 385 Amps, making it ideal for applications that require substantial power management.

Encased in an IP20-rated enclosure that complies with NEMA Type 1 standards, this unit is designed for use in standard indoor environments where protection against dust and moisture is essential. The human-machine interface consists of a full numeric LCD that is door-mounted, allowing for straightforward interaction and monitoring.

The drive operates without an integrated braking system but features an adjustable bus undervoltage trip for added safety and operational flexibility. Overheating protection is managed by a microprocessor that monitors a heat sink thermistor.

The logic control system allows for a ride-thru capability of 0.25 seconds when the drive is not running, ensuring that there are minimal disruptions during power disturbances. Furthermore, the drive can sustain power during full load conditions for up to 15 milliseconds, which is critical for maintaining performance during brief voltage drops. Overall, the 20DD385ACENNBRNNN is a robust choice for reliable motor control in demanding industrial applications.
