20DC072A3EYNACNNN

The part number 20DC072A3EYNACNNN from Allen-Bradley operates as an adjustable frequency AC drive, effective for industrial applications requiring precise motor control. This model functions on a voltage of 400 volts AC within a three-phase configuration. It manages a current of up to 72 amps (normal-duty), making it suitable for high-demand environments.

The drive features an enclosure rated IP20 according to NEMA Type 1 standards, offering basic protection against solid objects and moisture. It includes a full numeric LCD, which facilitates straightforward interaction for users wanting to monitor and adjust settings easily.

In terms of technical safety, the device utilizes IGBT braking, enhancing its control capabilities during operation. It also provides an adjustable bus undervoltage trip feature, which can be fine-tuned depending on application needs. To prevent overheating, the heat sink thermistor operates under the supervision of a microprocessor that initiates a trip when excessive temperatures are detected.

When the drive is not actively running, it incorporates a logic control ride-thru for 0.25 seconds, ensuring stability during brief power interruptions. Additionally, the drive maintains its functionality for 15 milliseconds at full load, providing resilience in fluctuating conditions. Overall, the 20DC072A3EYNACNNN combines advanced features intended to enhance performance and reliability in demanding control applications.
