20DD385N3ENNBNNNN

The Allen-Bradley part number 20DD385N3ENNBNNNN is classified as an adjustable frequency AC drive, designed for efficient operation in three-phase applications. It runs at a voltage of 480V AC and is rated for normal-duty currents of up to 385 amps, making it adept at handling significant electrical demands.

This model has an open enclosure rated IP00, complemented by a conformal coat, which aids in providing essential protection against environmental factors, although it is not meant for harsh conditions. The human-machine interface consists of a full numeric LCD, allowing users to access and configure parameters directly.

While there is no braking capability, the drive includes an adjustable bus undervoltage trip feature, enhancing its operational safety. Heat management is addressed through a thermistor that is actively monitored by a microprocessor, which triggers an overtemperature trip when necessary to prevent thermal issues.

For operational stability, this drive enables logic control ride-thru for a duration of 0.25 seconds when not actively running. In cases of electrical interruptions, it offers a power ride-thru capability lasting 15 milliseconds at full load, ensuring continued performance during brief power disturbances. Overall, the 20DD385N3ENNBNNNN drive is engineered for reliability in various industrial automation applications.
