20DD040A3NYNANDAL

The 20DD040A3NYNANDAL is an adjustable-frequency AC drive from the Allen-Bradley PowerFlex 700S series designed for robust performance in industrial settings. Operating at 480V AC, it is configured for three-phase applications. This drive manages a maximum normal-duty current of 40 amps, suitable for demanding power needs.

The device is housed in an enclosure rated IP20, in accordance with NEMA Type 1 specifications, providing sufficient protection from dust and incidental contact. It features a full numeric LCD that enables users to monitor and adjust settings conveniently, though no additional documentation is supplied with the unit.

For operational safety, the drive includes an IGBT braking system, delivering efficient stopping and controlling capabilities. It also incorporates an adjustable bus undervoltage trip, allowing customization based on specific operational parameters. A heat sink thermistor continuously monitors temperature levels through a microprocessor, initiating an overtemperature trip when required, ensuring reliable operation over time.

The drive supports a logic control ride-thru capability of 0.25 seconds while not actively running, ensuring operational continuity. Additionally, during power fluctuations, it can handle power ride-thru for 15 milliseconds at full load, thus contributing to its effectiveness in maintaining performance stability under varying conditions.
