The 20DD300N0ENNB6CNL is an adjustable-frequency AC drive in the Allen-Bradley PowerFlex 700S series. It is designed to operate efficiently at 480V AC and handle three-phase input. With a maximum normal-duty current rating of 300 amps, it is engineered to manage demanding applications that require high power.
It is encased in an enclosure rated IP20, offering appropriate protection in accordance with NEMA Type 1 standards. The human-machine interface is a blank cover, simplifying the design for integration into existing systems.
This model does not incorporate a braking mechanism, which is standard in some similar products. The adjustable bus undervoltage trip enhances operational safety. The system includes a heat sink thermistor, monitored by an internal microprocessor, to prevent overheating issues through effective management.
The logic control ride-thru feature maintains power for 0.25 seconds during inactive periods, which is critical during brief interruptions. The drive is capable of sustaining power ride-thru for a duration of 15 milliseconds while at full load, ensuring functionality during temporary power disruptions. Overall, the 20DD300N0ENNB6CNL is tailored for reliable performance in various industrial motor applications.
