20DD460N3ENNBNNNN

The 20DD460N3ENNBNNNN model is another robust offering from Allen-Bradley in the PowerFlex 700S series, designed for adjustable frequency applications. It operates effectively at a voltage rating of 480 volts AC and is configured for three-phase power inputs. This unit features a significant input amp capacity of 460 amps, accommodating heavy-duty applications comfortably.

Configured as an open IP00 enclosure, the drive is suitable for environments that do not require extensive protection from dust or moisture. Operating this drive is facilitated through a full numeric LCD, allowing users to configure and monitor settings conveniently. The drive does not incorporate a braking mechanism, which may be suitable for operations where continuous motion is exercised without the need for immediate stopping capability.

Safety features include an adjustable bus undervoltage trip to manage potential drops in voltage safely. The heat sink thermistor is supervised by a microprocessor, which triggers an overtemperature trip to prevent overheating. Notably, this drive offers 0.25 seconds of logic control ride-thru when not actively running, enhancing system stability during short interruptions. For power fluctuations at full load, a power ride-thru capability is available, lasting for a duration of 15 milliseconds, ensuring reliability in performance even during transient conditions.
