20DJ261N3NNNB1NNA

The Allen-Bradley 20DJ261N3NNNB1NNA is an advanced adjustable frequency AC drive engineered to meet the needs of modern industrial applications. Capable of operating at a voltage of 600V AC, this unit is configured for three-phase operations and supports a substantial input current of 261 amps, facilitating the control of powerful motors and complex machinery.

The drive is designed with an open-style enclosure (IP00), which allows unrestricted airflow and easy maintenance access. Although it does not include an integrated braking system, it features a full numeric LCD to aid in monitoring and configuration, providing essential operational data at a glance.

System integrity is enhanced through the inclusion of an adjustable bus undervoltage trip, enabling custom settings to protect against low-voltage scenarios. For thermal regulation, a heat sink thermistor is closely monitored by a microprocessor, ensuring the unit remains within safe temperature limits to prevent damage and maintain operational efficiency.

The 20DJ261N3NNNB1NNA also provides necessary backup functions, with a logic control ride-thru capability of 0.25 seconds during idle periods, which helps maintain stability in the event of brief power interruptions. Additionally, it can sustain functionality for up to 15 milliseconds at full load during power disturbances, further enhancing reliability and performance in demanding applications. Overall, this adjustable frequency drive is suitable for environments that require regular heavy-duty motor control and precise operational adjustments.
