The 20DD300N3NYNBCNNN is categorized as an adjustable frequency AC drive within the PowerFlex 700S series from Allen-Bradley. This unit supports three-phase operation with a voltage specification of 480V AC and has a maximum normal-duty capacity of 300 amps. Its construction includes an IP20-rated enclosure that adheres to NEMA Type 1 standards, making it suitable for indoor installations.
User interaction is facilitated through a full numeric LCD, though the drive does not come with any user manuals or documentation. The drive utilizes IGBT technology for braking, providing an efficient means of managing motor speed and control. An adjustable bus undervoltage trip adds to its safety features, allowing users to configure the device according to operational needs.
For thermal management, a heat sink thermistor is built into the design and is continuously monitored by a microprocessor to prevent overheating. The drive also ensures operational continuity with a logic control ride-thru duration of 0.25 seconds during non-operation. In scenarios of full load conditions, it can sustain power for a mere 15 milliseconds during power interruptions, ensuring minimal disruption in performance and reliability in applications.
