20DD261A3EYNNEBSE

The 20DD261A3EYNNEBSE from Allen-Bradley is an adjustable frequency AC drive that operates at a nominal input voltage of 480V AC. This unit is specifically designed for three-phase applications and is capable of handling an input current of up to 261 amps, making it suitable for demanding industrial environments. The drive is housed in an enclosure rated at IP20, compliant with NEMA Type 1 standards, ensuring protection against dust and contact in typical indoor applications.

User interaction is facilitated by a full numeric LCD, which allows for easy monitoring and configuration of the drive's settings. A quick start guide is included to aid users in setup and initial configuration. The braking system is based on IGBT technology, providing efficient control during operation.

For safety features, the drive includes an adjustable bus undervoltage trip, allowing users to customize operational parameters according to their needs. A heat sink thermistor, monitored by a microprocessor, offers additional safety by preventing overheating through an automated overtemp trip.

The drive can maintain logic control ride-thru performance for 0.25 seconds when the unit is inactive. This feature is beneficial in maintaining operational stability during brief power interruptions. Furthermore, it allows for power ride-thru during full load conditions for up to 15 milliseconds, ensuring continued operation and reliability in critical applications. Overall, the 20DD261A3EYNNEBSE is a robust solution offered by Rockwell Automation, tailored for versatility and efficiency in various settings.
