20DD022A3NYNANCAL

The Allen-Bradley part number 20DD022A3NYNANCAL is a robust adjustable frequency AC drive designed for precise control in three-phase applications. This device is characterized by its operation at 480V AC with a maximum normal-duty current of 22 amps, making it well-suited for various demanding applications in industrial settings.

Housed in an IP20-rated NEMA Type 1 enclosure, this drive provides reliable protection against dust and minor moisture exposure, suitable for typical indoor environments. The drive features a full numeric LCD, offering users a straightforward interface for monitoring and configuration purposes.

Integrated within this model is an IGBT brake, which enhances motor control during operation. The bus undervoltage trip can be adjusted to meet specific operational requirements, providing flexibility for diverse setups. Additionally, the heat sink thermistor is actively monitored by a microprocessor, ensuring safe operating temperatures by triggering an overtemperature trip when necessary.

This unit supports logic control ride-thru of up to 0.25 seconds, which allows for continued operation even during brief interruptions. Furthermore, the power ride-thru capability can sustain functionality for 15 milliseconds under full load conditions, emphasizing its reliability during transient disruptions in the power supply.
