20DD385N3NNNB1NNA

The Allen-Bradley 20DD385N3NNNB1NNA is a versatile adjustable-frequency AC drive designed for effective operation in industrial environments. It operates with a 480V AC input consisting of three phases and can handle a substantial normal-duty current of 385 amps.

It comes in an open-type enclosure rated IP00, which is further enhanced with a conformal coating to protect against environmental factors. The drive features a full numeric LCD, which aids in providing necessary information and status updates but does not include any accompanying documentation for reference.

This model does not integrate a braking system, making it suited for specific applications where such functionality is unnecessary. The device is equipped with an adjustable bus undervoltage trip feature, which helps maintain operational safety standards by preventing unexpected failures.

A monitored heat sink thermistor manages temperature levels, signaling the microprocessor to respond to over-temperature conditions, ensuring the drive operates within the required thermal limits. Furthermore, this drive has a logic control ride-thru capability of 0.25 seconds when it is not running, which safeguards against brief power interruptions. In terms of performance resilience, it can sustain power ride-thru capabilities for up to 15 milliseconds while under full load, making the 20DD385N3NNNB1NNA an ideal choice for various industrial motor control applications.
