The Allen-Bradley 20DD385ACENNBNGNE is part of the PowerFlex 700S series, designed as an adjustable frequency AC drive suitable for various industrial applications. This model operates on a three-phase system with a voltage rating of 480V AC, providing a maximum normal-duty current of 385 amps. Such specifications make it ideal for high-demand motor control scenarios.
It is protected by an enclosure rated at IP20, adhering to NEMA Type 1 standards, ensuring adequate protection in typical indoor environments. The drive is equipped with a full numeric LCD, conveniently mounted on the door for user-friendly monitoring and parameter adjustment.
The unit features no braking mechanism; however, it is equipped with an adjustable bus undervoltage trip, which allows users to customize the operational parameters according to their needs. The heat sink thermistor actively monitors the operating temperature and is managed by a microprocessor for automatic overtemperature protection.
For stability, the drive supports a logic control ride-thru of 0.25 seconds when not actively running. Additionally, it allows a power ride-thru of 15 milliseconds at full load, which helps to safeguard operations during brief power interruptions. Overall, the 20DD385ACENNBNGNE provides a blend of reliability and efficiency in motor control applications.
