The 20DD385A3ENNBCNNN adjustable frequency AC drive is manufactured by Allen-Bradley as part of the PowerFlex 700S series. This unit operates at a nominal voltage of 480V AC and is designed for three-phase applications, providing a normal-duty current capacity of 385 amps. Its design promotes reliable operation in diverse industrial setups.

The drive is housed in an IP20 enclosure, adhering to NEMA Type 1 specifications, which makes it appropriate for use in standard indoor settings. A full numeric LCD serves as the interface for users, allowing for easy monitoring and adjustment of parameters.

While the 20DD385A3ENNBCNNN does not incorporate a braking system, it features an adjustable bus undervoltage trip, providing flexibility in various operational scenarios. For added safety, thermal conditions are monitored by a heat sink thermistor that functions under the control of an integrated microprocessor, triggering an overtemperature protection mechanism when necessary.

Regarding operational resilience, the logic control ride-thru feature provides stability for 0.25 seconds when the drive is not actively running. The power ride-thru capability allows the unit to maintain functionality for 15 milliseconds at full load, which ensures continuation of operation even during brief power overlaps. The combination of these features makes the 20DD385A3ENNBCNNN a robust choice for industrial motor control applications.
