20DD034A3QYNARNNN

The 20DD034A3QYNARNNN, a model from the PowerFlex 700S catalog by Allen-Bradley, serves effectively as an adjustable frequency AC drive. This unit is rated for use in three-phase electrical systems and operates at 480V AC.

It is capable of handling an input current of 34 amps. To protect its internal components, it is housed in an enclosure rated IP20 with compliance to NEMA Type 1 standards. This layout is ideal for standard industrial applications, where safety and reliability are prioritized.

Users can interact with the drive via a full numeric LCD, facilitating straightforward monitoring and adjustments to operational settings. The model lacks accompanying documentation, so prior knowledge may be essential for optimal setup.

For dynamic motor control, the drive utilizes an IGBT braking system. To enhance safety, it features an adjustable bus undervoltage trip, allowing users to customize thresholds based on operational demands. Additionally, a heat sink thermistor that monitors conditions through a microprocessor helps prevent overheating by triggering overtemperature trips as necessary.

The 20DD034A3QYNARNNN drive includes a logic control ride-thru capability for 0.25 seconds during inactive periods, maintaining stability in power supply fluctuations. It also provides power ride-thru functionality for brief interruptions of up to 15 milliseconds at full load, ensuring continued operation under varying conditions.
