20DD261A0EYNNNCSL

The Allen-Bradley model 20DD261A0EYNNNCSL is an advanced adjustable frequency AC drive designed for demanding applications. Operating at 480V AC, it is engineered to support a substantial input current of 261 amps specifically within three-phase electrical systems.

This unit is encased in an IP20-rated, NEMA Type 1 enclosure that permits it to be safely utilized in a controlled indoor environment. The device's human interface consists of a blank cover, eliminating unnecessary controls and simplifying installation. Accompanying the drive is a quick start guide to assist with seamless setup and operation.

Significant features include an IGBT braking system designed to enhance reliability under varying operational conditions. The adjustable bus undervoltage trip feature allows users to configure this device based on specific application requirements. Moreover, the heat sink thermistor is actively monitored by an internal microprocessor to trigger an overtemperature protection mechanism as needed.

The device provides a logic control ride-thru capability of 0.25 seconds during which the drive is not actively running. In conditions where input power fluctuates, the drive can sustain power ride-thru functionality for up to 15 milliseconds, ensuring stability during brief supply disruptions. This combination of performance and protection attributes makes the 20DD261A0EYNNNCSL suitable for a diverse range of industrial motor control applications.
