The part number 20DD300A0NYNBCNNN is an adjustable frequency AC drive made by Allen-Bradley, which is part of Rockwell Automation. Operating on a three-phase system at 480 volts AC, this unit supports an input current of up to 300 amps, making it ideal for demanding applications. It features an IP20-rated enclosure according to NEMA Type 1 standards, providing minimal protection for dry and indoor environments. A blank cover serves as the human interface, meaning adjustments and monitoring must be done externally, as no documentation is provided with this unit.
This AC drive uses IGBT technology to enhance operational efficiency during braking situations. Its adjustable bus undervoltage trip feature allows for safety customization, ensuring the drive operates within desirable voltage limits. The unit is equipped with a heat sink thermistor that is observed by a microprocessor, which provides overtemperature protection to maintain operational stability. Logical control functions allow for 0.25 seconds of ride-thru time when idle, and it can sustain power ride-thru support for 15 milliseconds at full load. Overall, the 20DD300A0NYNBCNNN drive is engineered for effective performance in various industrial motor control scenarios.
