20DD040A3EYNARABE

The Allen-Bradley part number 20DD040A3EYNARABE is categorized as an adjustable frequency AC drive. This model is specifically designed for three-phase operation at a nominal voltage of 480V AC. It supports a maximum normal-duty current of 40 amps, making it suitable for various industrial applications requiring precision and reliability.

The drive is housed in a durable enclosure that meets IP20 and NEMA Type 1 specifications, ensuring adequate protection from dust and impacting objects in typical installation environments. Users can easily interact with the system through a full numeric LCD, which allows for operational monitoring and adjustments without complexity.

Included in the design is an IGBT braking system, which enhances the overall performance and efficiency of the drive. The adjustable bus undervoltage trip offers an additional layer of customization to safeguard against low voltage conditions, ensuring system integrity. Thermal management is supported by a heat sink thermistor that is actively monitored, with the microprocessor overseeing temperature control and activating over-temp trips when necessary.

For enhanced operational stability, the drive offers a logic control ride-thru period of 0.25 seconds when not actively running, helping to maintain functionality during brief interruptions. Furthermore, it is equipped with power ride-thru capabilities of 15 milliseconds at full load, contributing to its effectiveness in demanding operational settings. This combination of features makes the 20DD040A3EYNARABE a robust solution for modern industrial automation needs.
