The 20DD385N3ENNBNDNL is an adjustable frequency AC drive manufactured by Allen-Bradley, part of Rockwell Automation’s PowerFlex 700S series. It operates on a three-phase system with an input voltage of 480V AC. This drive is capable of handling a normal-duty current of 385 amps, which makes it well-suited for high-demand applications.

Designed with a user interface that includes a full numeric LCD, the drive allows for easy monitoring and operation. The unit has an open enclosure rated IP00, equipped with a conformal coat for improved durability against environmental factors.

While the drive model does not come with a braking mechanism, it features an adjustable bus undervoltage trip to enhance safety. Thermal regulation is managed through a heat sink thermistor, which is monitored by a microprocessor. This system ensures that overheating issues are promptly addressed by triggering an overtemperature trip when necessary.

Additionally, the drive supports logic control ride-thru for up to 0.25 seconds when idle. It is capable of maintaining power ride-thru for 15 milliseconds at full load, ensuring operational stability during brief power disruptions.
