The Allen-Bradley 20DD011A3NYNA1DNK is part of the PowerFlex 700S series and functions effectively as an adjustable-frequency AC drive. It's designed for three-phase applications and operates at a voltage level of 480V AC. This drive can accommodate a normal-duty current of up to 11 amps, allowing it to manage substantial power loads efficiently.
Housed in an IP20-rated enclosure, compliant with NEMA Type 1 standards, it provides adequate protection for its internal components in indoor environments. The drive lacks any accompanying documentation but features a full numeric LCD screen that provides necessary operational feedback.
An important feature of this model is its IGBT braking system which facilitates control over motor functions. The system includes protections such as an adjustable bus undervoltage trip, ensuring that performance remains stable under fluctuating input conditions. The unit also incorporates a heat sink thermistor actively monitored by a microprocessor to prevent overheating through overtemp trips.
In scenarios where external power interruptions occur, the drive supports a logic control ride-thru period of 0.25 seconds. Additionally, it has a power ride-thru time of 15 milliseconds, allowing it to handle temporary discrepancies at full load, enhancing reliability in continuous applications.
