20DD261N0ENNBNNNN

The Allen-Bradley 20DD261N0ENNBNNNN adjustable frequency AC drive is designed to optimize motor control in various applications. This model operates efficiently at a voltage rating of 480V AC and supports three-phase power configurations. Capable of handling an input current of 261 amps, it is suitable for demanding operational environments.

The enclosure meets both IP20 and NEMA Type 1 specifications, providing adequate protection for its internal components in typical indoor applications. Unlike some models, this drive's human-machine interface does not include user controls, as indicated by its blank cover.

For user convenience, a quick start guide is included to aid in setup and initial operation. The drive does not have an integrated braking system but compensates with features like an adjustable bus undervoltage trip, which allows for tailored operational parameters according to user requirements.

Thermal management is facilitated by a heat sink thermistor monitored by a microprocessor, preventing overheating incidents. Additionally, the drive incorporates logic control ride-thru capabilities for up to 0.25 seconds when not actively running. In case of a power fluctuation, it can sustain operation for 15 milliseconds under full load conditions, enhancing reliability and performance across various industrial tasks.
