20DD022A3NYYA1NNA

The Allen-Bradley 20DD022A3NYYA1NNA is an adjustable frequency AC drive tailored for efficient control of three-phase systems operating at 480V AC. With the capacity to handle a normal-duty current of 22 amps, this unit ensures robust performance for various industrial applications. The drive’s design includes a full numeric LCD that facilitates straightforward monitoring and interaction.

Housed in an IP20 enclosure compliant with NEMA Type 1, it assures adequate protection against dust and minor contact. The unit lacks external documentation, which may necessitate reliance on other resources for setup details. The braking mechanism utilizes IGBT technology, providing smoother control over motor operations. Furthermore, an adjustable bus undervoltage trip feature is included to enhance user safety and adapt the device for precise functioning.

To regulate temperature, the heat sink thermistor is actively monitored by a microprocessor, which can trigger an overtemperature trip when required. For operational resilience, the drive maintains logic control ride-thru for up to 0.25 seconds while not running, ensuring stability during brief power outages. It also supports power ride-thru capabilities for 15 milliseconds at full load, contributing to its effectiveness in mission-critical applications.
