20DD125A0EYNANBNL

The 20DD125A0EYNANBNL from Allen-Bradley, under the Rockwell Automation brand, is classified as an adjustable frequency AC drive designed for robust motor control. Operating under a three-phase system, this drive can handle an input voltage of 480V AC and an input current of up to 125 amps, making it well-suited for diverse industrial tasks.

This unit is constructed within an IP20-rated enclosure that meets NEMA Type 1 standards, ensuring protection against dust and moisture. It features a blank cover for its human-machine interface, keeping the design simple. Accompanying this model is a quick start guide for efficient setup and integration.

The braking mechanism utilizes IGBT technology, contributing to effective motor control. The adjustable bus undervoltage trip offers added safety, allowing users to customize the operational limits. Thermal regulation is provided by a heat sink thermistor, which is continuously monitored by a microprocessor to detect overtemperature conditions and activate protective measures when necessary.

For operational resilience, the drive maintains logic control ride-thru capabilities for 0.25 seconds during inactive periods, providing stability in case of brief power disruptions. Additionally, it can sustain a power ride-thru of 15 milliseconds at full load, ensuring reliable performance even during momentary interruptions. The combination of these features bolsters the functionality of the 20DD125A0EYNANBNL in demanding environments.
