The Allen-Bradley part number 20DD156A3ENNACNBN belongs to the PowerFlex 700S series and is classified as an adjustable frequency AC drive. It operates effectively at 480V AC and is compatible with three-phase electrical systems. The device supports a normal-duty current of up to 156 amps, making it suitable for high-demand applications.

The drive features an IP20 enclosure, which conforms to NEMA Type 1 standards and provides minimal protection against dust and moisture. Operators can interact with the unit through a full numeric LCD, which displays pertinent information about the drive's operation.

This model is designed without a braking system, focusing on reliable and efficient motor control. To enhance safety, it includes an adjustable bus undervoltage trip, allowing users to set specific thresholds based on operational needs. Furthermore, the heat sink thermistor is actively monitored by an integrated microprocessor, which triggers an overtemperature trip if necessary.

For operational continuity, the logic control allows for a ride-thru duration of 0.25 seconds when the drive is not in use. Additionally, the drive supports power ride-thru capabilities for 15 milliseconds when fully loaded, ensuring consistent performance during transient interruptions.
