The 20DD077A3NNNACDCL is an adjustable frequency AC drive within the PowerFlex 700S series from Allen-Bradley. This unit is built to operate efficiently on a voltage of 480V AC in three-phase configurations. It has a normal-duty current rating of 77 amps, making it suitable for various demanding motor control tasks.

The unit features an IP20-rated enclosure, compliant with NEMA Type 1 standards, ensuring protection from environmental factors in indoor settings. Interaction with the device is facilitated through a full numeric LCD human-machine interface, but documentation is not provided. Notably, no braking mechanism is included in this model.

Safety features include an adjustable bus undervoltage trip, allowing users to set specific voltage thresholds. The heat sink is equipped with a thermistor monitored by a microprocessor, which protects against overheating by triggering an overtemperature shutdown if required.

This drive has logic control ride-thru capabilities lasting 0.25 seconds during non-operational periods, and the power ride-thru duration is 15 milliseconds under full load conditions. The combination of these features makes the 20DD077A3NNNACDCL a reliable option for industrial applications.
