The 20DD460A3ENNBNGNE is a power-efficient adjustable frequency AC drive from the Allen-Bradley PowerFlex 700S series. It is built to function optimally at 480V AC, accommodating a substantial normal-duty current of 460 amps across three-phase systems. The device is housed in an enclosure that meets the IP20 and NEMA Type 1 standards, is suitable for industrial environments, and ensures some level of protection against environmental factors.
A full numeric LCD serves as the drive's human interface, facilitating control and operation. It makes parameter adjustments and monitoring straightforward for users.
This AC drive does not include an integrated brake system but is equipped with an adjustable bus undervoltage trip feature, which helps safeguard the system from low-voltage scenarios. Overheating is managed through a heat sink thermistor, which is continuously monitored by a microprocessor, providing a reliable mechanism to prevent temperature-related failures.
For added resilience during power fluctuations, the drive supports logic control ride-thru for a duration of 0.25 seconds when not actively running. Under full-load conditions, it also maintains continuity for 15 milliseconds via its power ride-thru capability, ensuring that operation continues smoothly during transient disturbances.
