The 20DD385A0ENNBNCNL from Allen-Bradley is part of the PowerFlex 700S series and contains notable attributes suited for variable motor control. It operates at 480V AC and is configured for three-phase electrical systems. This model can accommodate a substantial normal-duty current capability of 385 amps, making it suitable for demanding applications.

Engagement is minimal, as this drive features a blank cover for the human-machine interface option, eliminating unnecessary components that might complicate operation.

The unit is housed in an IP20-rated enclosure, adhering to NEMA Type 1 standards, which offers standard indoor environmental protection. While this drive does not include a braking mechanism, it does come with an adjustable bus undervoltage trip designed to safeguard the system from potential voltage drops.

Thermal management is effectively handled by a heat sink thermistor, monitored by an internal microprocessor that initiates an overtemperature trip when necessary. The logic control ride-thru capabilities allow for up to 0.25 seconds of continued operation during brief interruptions. Additionally, the unit ensures a power retention period of 15 milliseconds under full load conditions, providing necessary stability during unexpected power fluctuations.
