The 20DE261A0ENNBNAEE adjustable frequency AC drive is part of the Allen-Bradley PowerFlex 700S line manufactured by Rockwell Automation. Operating efficiently at 600V AC, this drive is intended for advanced three-phase power applications. With a normal-duty current rating of 261 amps, it is robust enough for demanding industrial environments.
The drive complies with NEMA Type 1 standards and is constructed with an IP20-rated enclosure, ensuring proper protection during operation. Its interface is a blank cover, which streamlines the design while preventing unauthorized access to the controls.
Safety features include an adjustable bus undervoltage trip that aids in maintaining operational integrity under fluctuating electrical conditions. Additionally, the unit monitors overtemperature situations via a heat sink thermistor, guided by a microprocessor for rapid response and prevention of damage.
This drive supports logic control ride-thru capabilities for 0.25 seconds when inactive, helping to maintain system stability during brief interruptions. It also ensures power ride-thru functionality for 15 milliseconds when operating under full load. This combination of features positions the 20DE261A0ENNBNAEE as a strong contender for industrial motor control applications.
