20DJ261N0NNNBNDNK

The Allen-Bradley 20DJ261N0NNNBNDNK is characterized as an adjustable frequency AC drive, engineered for advanced control capabilities. It operates at a nominal input voltage of 600 volts AC and is suitable for three-phase applications. Designed to accommodate a robust input current of 261 amps, this drive ensures reliable performance in industrial settings.

The device comes in an open enclosure with a rating of IP00, which allows for direct access but lacks protective covering. Therefore, it is ideal for controlled environments where exposure to dust or liquids is minimal. Notably, this model features a human interface without any display or keypad, relying on external systems for operation feedback.

The drive incorporates an adjustable bus undervoltage trip feature, which allows customization of the trip settings according to user requirements, maximizing operational safety. Additionally, it is equipped with a heat sink thermistor that is monitored by a microprocessor for overtemperature protection. This functionality is integral to maintaining optimal performance levels.

During idle periods, the logic control can sustain a ride-thru duration of 0.25 seconds, facilitating a stable operational response. Moreover, the drive is designed with power ride-thru capabilities, allowing for a brief maintenance of power for up to 15 milliseconds at full load. This added resilience contributes to overall system stability during electrical variations.
