20DD034A3NYNA5NBA

The adjustable frequency AC drive, identified as part number 20DD034A3NYNA5NBA from Allen-Bradley, operates effectively within the PowerFlex 700S series. This drive is meticulously designed for use with three-phase power systems, operating at 480V AC. It can handle a significant input current of 34 amps, making it suitable for various industrial applications.

With an enclosure rated IP20 that adheres to NEMA Type 1 standards, the drive offers basic protection against dust and moisture intrusion. The human-machine interface is facilitated through a full numeric LCD, which allows users to interact with the system for monitoring and diagnostics. Notably, no documentation is available with this unit, which may require users to rely on their expertise or operational familiarity.

The drive employs IGBT braking technology to enhance operational efficiency. An adjustable bus undervoltage trip feature adds a layer of customizable protection for the input power conditions. Additionally, thermal management is efficiently handled by a heat sink thermistor that is continuously monitored by a microprocessor, ensuring any overheating conditions are promptly addressed.

For added reliability, the drive includes logic control ride-thru capability, which lasts for 0.25 seconds when the drive is not active. Under full load conditions, the system can maintain a power ride-thru duration of 15 milliseconds. These features collectively emphasize the drive's preparedness for maintaining stable operations during transient disturbances.
