20DD385N3ENNBNANL

The 20DD385N3ENNBNANL model from Allen-Bradley is an adjustable frequency AC drive designed for demanding industrial environments. Functioning at a voltage of 480V AC, this unit is structured for three-phase electrical systems. Capable of handling a normal-duty current of 385 amps, it is engineered to support substantial power requirements for various applications. The drive's open enclosure, rated at IP00, features a conformal coating that enhances its ability to resist environmental factors, thus extending its operational life in diverse settings.

A full numeric LCD facilitates user interaction, allowing for straightforward monitoring and adjustment of settings. Although this drive does not have a braking mechanism, it includes an adjustable bus undervoltage trip feature, which helps to optimize the system's safety and performance.

The unit's thermal management is critical; it includes a heat sink thermistor that is actively monitored by a microprocessor to guard against overheating by triggering protective measures. In addition to basic monitoring features, the drive provides a logic control ride-thru capability of 0.25 seconds when the unit is not in operation, ensuring a buffer during momentary power disruptions. For stability under load, the power ride-thru duration lasts up to 15 milliseconds, facilitating seamless operational continuity in high-stress conditions. Overall, the 20DD385N3ENNBNANL is engineered to deliver efficient and reliable performance in various industrial applications.
