20DD460A3ENNBNASE

The 20DD460A3ENNBNASE adjustable frequency AC drive is part of Rockwell Automation's Allen-Bradley PowerFlex 700S series. Designed primarily for three-phase applications, it operates using a 480V AC input voltage and can manage an impressive current capacity of 460 amps. Its robust design makes it suitable for various demanding industrial environments.

This drive is equipped with an IP20 enclosure rated to NEMA Type 1 standards, which offers adequate protection against dust and accidental contact. A full numeric LCD facilitates user access and clearly displays operational parameters and settings.

The 20DD460A3ENNBNASE does not incorporate a braking feature; however, it compensates with an adjustable bus undervoltage trip that enhances operational safety. Thermal management is assured by a heat sink thermistor, which the microprocessor actively monitors to prevent overheating.

Logic control functionality ensures a ride-thru capability of 0.25 seconds when the drive is not actively running, which helps maintain system stability during brief power interruptions. Furthermore, the drive is capable of sustaining power ride-thru performance for 15 milliseconds at full load, thereby ensuring continued operation even in fluctuating power conditions. Overall, the 20DD460A3ENNBNASE provides reliable and efficient performance for advanced motor control requirements.
