The Allen-Bradley 20DD385A0ENNBNCNK is an adjustable-frequency AC drive optimized for various industrial applications. Operating at 480V AC, this unit is configured for three-phase operation. It can handle a normal-duty current of 385 amps, making it suitable for demanding motor control tasks.

This drive is built within an IP20-rated enclosure that aligns with NEMA Type 1 specifications, ensuring basic protection in standard environments. Unlike many other drives, this model features a blank cover, simplifying its integration into control systems without onboard user controls.

The 20DD385A0ENNBNCNK does not incorporate a braking system. However, it is equipped with an adjustable bus undervoltage trip, enhancing its operational safety during fluctuations. Furthermore, a heat sink thermistor is included, which is actively monitored by an internal microprocessor to ensure the drive does not exceed its thermal limits and triggers an over-temp trip as needed.

During non-operational states, the drive supports a logic control ride-thru period of 0.25 seconds, which helps maintain settings in case of brief power losses. Additionally, it can sustain power for 15 milliseconds at full load, contributing to its reliability across various applications.
