20DD261A0ENNBNGNE

The Allen-Bradley model 20DD261A0ENNBNGNE belongs to the PowerFlex 700S series as an adjustable frequency AC drive. Designed for three-phase applications, this unit operates effectively at a voltage of 480 volts AC. It has a robust input current rating of 261 amps, making this drive suitable for demanding industrial environments.

This drive features an IP20-rated enclosure compliant with NEMA Type 1 standards. Such an enclosure ensures essential protection against dust and moisture while allowing for efficient thermal dissipation during operation. Its human interface is simplified with a blank cover, indicating no built-in controls for user interaction.

The power drive does not include braking capabilities. However, it incorporates an adjustable bus undervoltage trip for operational flexibility and enhanced safety. A thermal management system is in place, featuring a heat sink thermistor that is actively monitored by a microprocessor, which will initiate an overtemperature trip if necessary to prevent damage.

The 20DD261A0ENNBNGNE also boasts a ride-thru capability of 0.25 seconds during idle periods, thereby ensuring stability in operation during temporary power outages. Furthermore, it can sustain operational functionality for 15 milliseconds at full load during power interruptions. This combination of features ensures reliable and efficient performance in varying industrial applications.
