The 20DD180A3NNNA2NBB is an adjustable-frequency AC drive by Allen-Bradley, part of the PowerFlex 700S series. Engineered for performance, this drive operates effectively at 480 volts AC in three-phase systems, handling a robust normal-duty current of up to 180 amps.
This unit features an IP20-rated enclosure that adheres to NEMA Type 1 standards, providing basic protection for internal components. The drive's human-machine interface is facilitated through a full numeric LCD, which enables straightforward operation. It is important to note that this model does not include any braking functionality.
For enhanced safety, it is equipped with an adjustable bus undervoltage trip feature, allowing users to set specific thresholds. Additionally, thermal protection is crucial in this design; a microprocessor monitors the heat sink thermistor to prevent overheating by initiating a trip if needed.
During brief periods of inactivity, the device supports a logic control ride-thru lasting 0.25 seconds, ensuring stability. Furthermore, it can sustain power for up to 15 milliseconds under full load during short voltage drops. Overall, the 20DD180A3NNNA2NBB drive offers essential performance features for various industrial applications.
