20DD261A3EYNB1NNA

The Allen-Bradley 20DD261A3EYNB1NNA operates as an adjustable frequency AC drive. It is a part of the PowerFlex 700S series, specifically designed for three-phase applications with an input voltage rating of 480V AC. With a substantial input current capacity of 261 amps, it is suited for various industrial uses where high performance is essential.

This drive features an IP20-rated enclosure that meets NEMA Type 1 standards, making it appropriate for indoor installations. The human-machine interface consists of a full numeric LCD that enables efficient monitoring and programming, allowing operators to interact with the system easily. The documentation provided includes a quick start guide to facilitate setup.

The drive employs IGBT braking technology, enhancing its operational efficiency and control capabilities. Included in its safety measures is an adjustable bus undervoltage trip feature, which protects against voltage sags. Additionally, a heat sink thermistor is continuously monitored by a microprocessor to prevent overheating, triggering a shut-off if necessary.

Moreover, the logic control ride-thru function ensures the drive can maintain stability for 0.25 seconds during non-operation periods. For power disturbances, it has a ride-thru capability of 15 milliseconds at full load, allowing for reliable performance during brief outages. Overall, the 20DD261A3EYNB1NNA addresses the rigorous demands of modern industrial environments with its robust design and functionality.
