20DD300A3ENNBNCBK

The Allen-Bradley 20DD300A3ENNBNCBK, part of the PowerFlex 700S series, functions as an adjustable frequency AC drive. This drive operates at a nominal voltage of 480V AC and supports three-phase configurations, making it suitable for a range of industrial applications. It is designed to manage an input current rating of 300 amps effectively.

Housed in an enclosure rated IP20 and compliant with NEMA Type 1 standards, this drive is well-equipped for indoor environments where it can be adequately protected from dust and light splashes. User experiences are enhanced through the presence of a full numeric LCD, which provides real-time operational information and settings.

This model does not include a braking feature; however, it compensates with an adjustable bus undervoltage trip to ensure operational safety. A significant aspect of the drive's design is the heat sink thermistor, which is continually monitored by a microprocessor to prevent overheating, ensuring reliable functionality and longevity.

The 20DD300A3ENNBNCBK also includes features for handling transient voltages. Specifically, it can sustain a logic control ride-thru duration of 0.25 seconds when the drive is not operational. Additionally, the power ride-thru feature allows the drive to maintain functionality for 15 milliseconds at full load, thereby enhancing its reliability in varying electrical conditions. For users, a quick start guide is included to streamline setup and configuration.
