20DD156A0NYNA1DNK

The 20DD156A0NYNA1DNK, part of the Allen-Bradley PowerFlex 700S series, serves as a robust adjustable frequency AC drive. It is engineered for three-phase operations at a voltage of 480V AC. With the capability of handling a normal-duty current of 156 amps, this drive is designed for high-demand industrial applications.

This unit comes in an enclosure rated as IP20, aligning with NEMA Type 1 certification, which is suitable for internal use in environments that don't expose it to significant moisture or dust. A notable feature of this drive is the blank cover that replaces a standard human-machine interface, emphasizing a straightforward design without unnecessary complexity. However, it does not come with any documentation.

Braking is accomplished via IGBT technology, ensuring effective stopping performance. The drive is also equipped with an adjustable bus undervoltage trip, allowing users to customize the drive's operational parameters for increased safety. Thermal management is addressed with a heat sink thermistor that is actively monitored by a microprocessor, providing reliable overtemperature protection during operation.

In addition, the drive supports logic control ride-thru capability, enabling it to maintain functionality for up to 0.25 seconds when not in operation. Furthermore, it can endure brief power interruptions for up to 15 milliseconds at full load, demonstrating its resilience in maintaining stable performance. The 20DD156A0NYNA1DNK is thus a crucial component for applications requiring dependable motor control and responsiveness.
