20DD500A3NNNBCGNE

The 20DD500A3NNNBCGNE model represents an adjustable frequency AC drive within the Allen-Bradley PowerFlex 700S series. Specifically designed for three-phase systems, this drive operates efficiently at a voltage level of 480V AC and is capable of managing an input current of 500 amps. This feature allows it to cater to high-power applications found in various industrial settings.

Made with a NEMA Type 1 compliant IP20 enclosure, the drive is protected against limited dust ingress and water splashes, ensuring suitable performance in certain indoor environments. The device includes a full numeric LCD which serves as the main interface for operators, enabling straightforward monitoring of performance metrics. However, it should be noted that this unit does not come with additional documentation.

The drive lacks a braking system but incorporates an adjustable bus undervoltage trip feature, allowing for flexibility in safety settings. Temperatures are kept in check via a heat sink thermistor, which is monitored by a built-in microprocessor to prevent overheating issues. Additionally, the unit supports a logic control ride-thru duration of 0.25 seconds, providing stability during brief power outages. It can also maintain power ride-thru for up to 15 milliseconds at full load, ensuring reliability during transitions. Overall, the 20DD500A3NNNBCGNE is engineered for effective motor control in demanding operational environments.
