The 20DD460A3ENNBENNN adjustable frequency AC drive, manufactured by Allen-Bradley, is engineered for three-phase motor control at 480V AC. This unit accommodates a normal-duty current capacity of 460 amps, facilitating its use in high-demand industrial tasks.
Designed following NEMA Type 1 specifications, the drive features an IP20 enclosure that provides protection against dust and minor contact. Its human-machine interface comprises a full numeric LCD, which simplifies user access to settings and operational data.
Without an integrated braking system, users must consider external alternatives for motor deceleration. Nonetheless, the drive enhances operational safety through an adjustable bus undervoltage trip setting. A notable feature is the heat sink thermistor, which is continuously monitored by a microprocessor to prevent overheating.
The 20DD460A3ENNBENNN also provides a logic control ride-thru duration of 0.25 seconds during non-operation, ensuring stability during brief power outages. Additionally, during peak operational loads, it maintains a power ride-thru capacity of 15 milliseconds. This combination of features equips the drive to fulfill the rigorous demands of various industrial environments while ensuring reliable performance.
