20DD156A0NNNANNNN

The 20DD156A0NNNANNNN from the PowerFlex 700S series is an adjustable frequency AC drive manufactured by Rockwell Automation under the Allen-Bradley brand. This drive operates on a three-phase system with a standard voltage of 480V AC, making it highly suitable for a wide array of industrial applications. It supports a normal-duty current of up to 156 amps. Its enclosure meets the standards of IP20 and NEMA Type 1 classification, ensuring physical protection in standard environments.

A blank cover is the human-machine interface option for the drive, indicating that there are no onboard controls integrated directly into the unit. Documentation is not provided, requiring users to rely on other resources for setup guidance. The drive is adeptly equipped with an IGBT braking system, enhancing its control capabilities during operation. Safety is prioritized with an adjustable bus undervoltage trip, safeguarding the unit against potential voltage falls that could affect performance.

Temperature monitoring is facilitated via a heat sink thermistor, which is observed by a microprocessor that triggers an overtemperature trip if it detects critical conditions. In terms of stability, the logic control ride-thru allows for a duration of 0.25 seconds when the drive is not actively running, while it can maintain a power ride-thru capability of 15 milliseconds under conditions of full load. This ensures continued operation during brief power interruptions, contributing to its reliability in demanding environments.
