20DD261A5EYNB1CSK

The 20DD261A5EYNB1CSK adjustable frequency AC drive, from the Allen-Bradley PowerFlex 700S series, operates efficiently on 480V AC. It is optimized for three-phase applications, capable of managing an input current of 261 amps effectively. This unit features an enclosure rated IP20, adhering to the NEMA Type 1 protection standards.

A prominent element of this drive is its simple programmable LCD, designed for enhanced user interaction. A quick start guide is included to facilitate initial setup and configuration. The design incorporates an IGBT braking system that supports motor control during dynamic operations.

To address fluctuating voltage conditions, this drive includes an adjustable bus undervoltage trip, allowing users to set the threshold according to their specific application needs. Thermal monitoring is achieved through a heat sink thermistor, continuously observed by a microprocessor. This setup ensures the drive's safety, triggering an overtemperature trip if required.

Additional features include logic control ride-thru capability lasting 0.25 seconds when the drive is not operating, which helps maintain operational stability. The power ride-thru feature allows continued operation for up to 15 milliseconds at full load during brief power interruptions, thereby enhancing reliability in various scenarios.
