20DD300N0NNNBNNNN

The 20DD300N0NNNBNNNN adjustable frequency AC drive, designed by Allen-Bradley, is intended for robust three-phase applications running at 480 volts AC. This unit can accommodate a significant normal-duty current of up to 300 amps, making it suitable for various high-demand scenarios. It is contained within an IP20-rated enclosure, adhering to NEMA Type 1 specifications, thus offering basic protection against dust and moisture in standard industrial settings.

The unit has a blank cover, indicating it does not feature a dedicated user interface for control or monitoring. This AC drive does not incorporate a braking system, but it does come equipped with an adjustable bus undervoltage trip, allowing for tailored protection settings to be applied based on the application requirements.

For thermal management, the device employs a heat sink thermistor that is monitored by a microprocessor, ensuring that the unit operates within safe temperature thresholds and triggers an overtemperature trip when needed. To ensure stability during brief power disruptions, the drive supports a logic control ride-thru capability lasting 0.25 seconds. Additionally, it provides power ride-thru support for up to 15 milliseconds while under full load, thus maintaining functionality during minor power fluctuations. The 20DD300N0NNNBNNNN is, therefore, engineered to deliver reliable performance across various industrial environments.
