The Allen-Bradley 20DD385A3ENNBCASE fits into the PowerFlex 700S series as an adjustable frequency AC drive. Designed for three-phase operation, it functions efficiently at 480 volts AC. It can manage a considerable normal-duty current of 385 amps.

The drive features an enclosure rated at IP20, in compliance with NEMA Type 1 standards, which provides basic protection suitable for indoor usage. A full numeric LCD is the human-machine interface, enabling straightforward monitoring and adjustments.

This model does not include a braking mechanism, but it is equipped with an adjustable bus undervoltage trip to enhance safety. Thermal management is provided by a heat sink thermistor, which is closely monitored by a microprocessor. This prevents overheating by triggering an over-temp trip when necessary.

Regarding operational continuity, the drive offers a logic control ride-thru capability of 0.25 seconds when it's not running. Furthermore, it can sustain power for up to 15 milliseconds under full load, ensuring reliability during transient power issues. The 20DD385A3ENNBCASE is designed for demanding environments, making it a practical choice for various industrial motor control applications.
