The 20DD300A3NNNNNBCE from Allen-Bradley is part of the PowerFlex 700S series and functions as an adjustable-frequency AC drive. Operating at a maximum input voltage of 480V AC, this unit is designed for three-phase applications. It is equipped to handle a normal-duty current of 300 amps, making it suitable for demanding industrial tasks.

This model features an IP20-rated enclosure in accordance with NEMA Type 1 standard, providing basic protection for indoor installations. A full numeric LCD serves as the human-machine interface, allowing users to monitor and adjust settings effectively.

Unlike some models, this drive does not have a braking system. An adjustable bus undervoltage trip is included to enhance safety and operational reliability. Additionally, the heat sink thermistor is monitored by a microprocessor, ensuring protection against overheating through an automatic trip feature.

For uninterrupted performance, the drive supports logic control ride-thru for 0.25 seconds while not running, ensuring settings are maintained during brief power disruptions. It also offers a power ride-thru capability for 15 milliseconds under full load conditions, contributing to its reliability in critical applications.
