20DD040A3EYNANDEL

The part number 20DD040A3EYNANDEL from Allen-Bradley is an adjustable-frequency AC drive designed for high-performance applications. It can operate at 480 volts AC and efficiently supports three-phase voltage systems with a maximum normal-duty current rating of 40 amps. This device falls within the PowerFlex 700S series, manufactured by Rockwell Automation and known for its reliability in industrial settings.

The drive's IP20-rated enclosure, complying with NEMA Type 1 specifications, provides essential protection against dust and accidental contact, making it suitable for various environments. The user interface is a full numeric LCD, ensuring that operators can easily interact with the drive's features.

This drive incorporates an IGBT braking system, enhancing performance and responsiveness. Additionally, it features an adjustable bus undervoltage trip, allowing users to customize safety parameters as per specific application needs. The heat sink thermistor is continuously monitored by a microprocessor, which activates an overtemperature trip in case of excessive heat, thus safeguarding the unit.

The drive also supports logic control ride-thru functionality for up to 0.25 seconds when not running, maintaining stability in transitional conditions. Additionally, it is capable of power ride-thru lasting 15 milliseconds at full load, ensuring operational continuity during short interruptions.
