20DD156A0EYNANNNN

The Allen-Bradley 20DD156A0EYNANNNN is an adjustable frequency AC drive tailored for robust operation in industrial environments. With a working voltage of 480 volts AC, this model is designed for three-phase connectivity. It can accommodate a maximum normal-duty current of 156 amps, making it suitable for demanding applications requiring reliable power management.

This drive is encased in an IP20 enclosure that complies with NEMA Type 1 standards, providing basic protection against dust and access. The unit has a blank cover, which means that no human-machine interface is included, streamlining its functionality for integration into existing systems.

Safety features in this drive include an adjustable bus undervoltage trip, which allows users to set thresholds according to their requirements. The braking system utilizes IGBT technology, providing reliable performance during operation. Additionally, the heat sink thermistor is monitored by a microprocessor to prevent overheating, employing an overtemperature trip if necessary.

When not actively operational, the logic control ride-thru feature permits a duration of 0.25 seconds, ensuring stability during brief interruptions. Furthermore, during full load conditions, it offers a power ride-thru capability for 15 milliseconds, enhancing reliability in critical applications. This design ensures that the Allen-Bradley 20DD156A0EYNANNNN drive can effectively meet the rigorous demands of modern industrial automation.
