20DD3P4A3NYYA1NBA

The 20DD3P4A3NYYA1NBA from Allen-Bradley, part of the PowerFlex 700S series, functions as an adjustable frequency AC drive. This product can accommodate a three-phase input voltage of 480V AC while supporting a maximum normal-duty current of 3.4 amps. It is designed with an IP20-rated enclosure, compliant with NEMA Type 1, ensuring adequate protection for indoor use. The inclusion of a full numeric LCD allows operators to interact seamlessly with the drive and easily monitor operational parameters.

Safety and efficiency are assured with its IGBT braking system, which contributes to the smooth operation and control of connected motors. The bus undervoltage trip feature is adjustable, providing flexibility to customize safety thresholds according to specific application needs. Furthermore, the built-in heat sink thermistor is actively monitored by a microprocessor, safeguarding against overheating by activating a trip if excessive temperatures are detected.

This model supports logic control ride-thru capability for 0.25 seconds when inactive, thereby maintaining operational stability during brief interruptions. Additionally, it includes a power ride-thru function that lasts for 15 milliseconds at full load, ensuring consistent performance during transient power losses. Overall, the Allen-Bradley 20DD3P4A3NYYA1NBA is a robust solution for precise motor control in various industrial applications.
