20DD040A3EYNA6NNB

The 20DD040A3EYNA6NNB is an adjustable frequency AC drive produced by Allen-Bradley within the PowerFlex 700S series. It is designed specifically for three-phase systems and operates at a nominal voltage of 480V AC. This drive can accommodate a maximum normal-duty current of 40 amps, delivering robust and efficient motor control.

The drive features an enclosure rated at IP20, meeting NEMA Type 1 classification, which offers basic protection against dirt and accidental contact. For user interaction, it is equipped with a full numeric LCD that provides clear display readings.

An IGBT braking system is integrated into the unit, enhancing its performance and control capabilities. Additionally, the adjustable bus undervoltage trip feature provides customization for specific operating requirements, helping to safeguard against unexpected voltage drops. A microprocessor actively monitors the heat sink thermistor to prevent overheating situations, which is crucial for ensuring reliable operation.

The model supports a logic control ride-thru duration of up to 0.25 seconds while the drive is not actively running, allowing for temporary interruptions in power without system failure. Furthermore, the drive can provide power ride-thru lasting up to 15 milliseconds at full load, ensuring continuity during brief power fluctuations. Overall, the 20DD040A3EYNA6NNB is engineered for durability and precision in demanding industrial applications.
