20DD248A3QYNA1CAL

The part number 20DD248A3QYNA1CAL is a robust adjustable frequency AC drive from Allen-Bradley, part of the PowerFlex 700S series. This drive operates on a 480V AC-rated voltage supply and is designed for three-phase connections. It can efficiently handle a normal-duty current of up to 248 amps, rendering it suitable for demanding industrial applications.

This model features an enclosure rated IP20, compliant with NEMA Type 1 standards, offering adequate protection for indoor installations where typical environmental factors are present. For user interaction, the drive utilizes a full numeric LCD, which simplifies parameter adjustments and monitoring.

The 20DD248A3QYNA1CAL drive employs IGBT braking technology, which enhances motor control performance and responsiveness. It includes an adjustable bus undervoltage trip, allowing users to set specific thresholds tailored to their operational requirements. For thermal safety, the unit has a heat sink thermistor that is continuously monitored by a microprocessor. This system ensures that overheating is promptly addressed by triggering an overtemperature trip when necessary.

For operational stability, the logic control feature allows for a ride-thru of 0.25 seconds when the drive is not in active use. Furthermore, it is equipped to maintain operation for 15 milliseconds at full load during power disturbances, providing reliability in critical applications. The 20DD248A3QYNA1CAL is engineered for efficient operation, ensuring dependable performance across various motor control scenarios.
