20DD3P4A3EYYA1NBA

The 20DD3P4A3EYYA1NBA adjustable frequency AC drive from Allen-Bradley is engineered to operate on a three-phase power supply featuring a nominal voltage of 480V AC. The unit is capable of accommodating a normal-duty current of 3.4 amps, making it suitable for various industrial applications.

This model is encased in an IP20-rated enclosure that meets NEMA Type 1 specifications. It is suitable for typical indoor use while providing a degree of environmental protection. Users can interact with the drive through a full numeric LCD, which facilitates both the display and configuration of the drive settings.

The 20DD3P4A3EYYA1NBA integrates an IGBT braking system, enhancing control during operation. Safety features include an adjustable bus undervoltage trip that allows users to tailor operational parameters according to specific needs. An embedded microprocessor actively monitors a heat sink thermistor, triggering a trip in the event of an overtemperature condition, ensuring that the device remains within safe temperature limits.

For added reliability, the logic control enables a ride-thru capability of 0.25 seconds while idle, maintaining system integrity during brief power interruptions. Additionally, the drive supports power ride-thru timeframes of 15 milliseconds at full load, which is crucial for continuous operation in demanding industrial settings. Overall, the 20DD3P4A3EYYA1NBA provides robust performance for applications that necessitate precise motor control.
