20DD3P4A0NYNA1NNA

The Allen-Bradley 20DD3P4A0NYNA1NNA adjustable frequency AC drive is designed for efficient motor control in three-phase systems. Operating at a voltage rating of 480V AC, this drive effectively accommodates a normal-duty current of up to 3.4 amps. Suitable for industrial applications, it ensures that motor speeds can be controlled precisely according to operational requirements.

Constructed with an IP20-rated enclosure that meets NEMA Type 1 standards, this unit provides essential protection for its internal components in controlled environments. The human-machine interface is a blank cover, allowing for a straightforward configuration without complicated displays.

Braking is managed through IGBT technology, enhancing the drive's capability to control motor dynamics effectively. An adjustable bus undervoltage trip feature enhances the unit's adaptability and operational safety. A microprocessor actively monitors a heat sink thermistor to prevent overheating, ensuring reliability and longevity.

For additional operational stability, the drive supports a logic control ride-thru of 0.25 seconds when inactive. In situations of brief power loss, it can maintain operation for 15 milliseconds at full load, ensuring continuity in sensitive processes. This model exemplifies essential engineering for demanding industrial applications where precision and reliability are crucial.
