The 20DD011A3EYYACNNN model from Allen-Bradley, part of the PowerFlex 700S series, functions as an adjustable-frequency AC drive. Suitable for three-phase systems, it operates at 480V AC. The drive supports normal-duty currents up to 11 amps, making it capable of effectively managing substantial motor loads.
This device is enclosed in a robust IP20 case compliant with NEMA Type 1 standards, providing adequate protection against common contaminants. Featuring a full numeric LCD, the human-machine interface allows for straightforward programming and monitoring.
In terms of functionality, the drive includes IGBT braking technology, which facilitates efficient stopping capabilities. It features an adjustable bus undervoltage trip to safeguard against low-voltage conditions. Additionally, the heat sink thermistor is closely monitored by a microprocessor, triggering an overtemp trip if necessary to prevent overheating.
Operational resilience is highlighted by the logic control ride-thru feature, which sustains function for 0.25 seconds when the drive is not actively running. When at full capacity, the power ride-thru lasts for 15 milliseconds, ensuring continued operation during brief power fluctuations.
