20DD077A0NNNAENNN

The 20DD077A0NNNAENNN adjustable frequency AC drive is a product of Allen-Bradley, part of Rockwell Automation's PowerFlex 700S series. This unit is designed specifically for a three-phase power supply at a voltage rating of 480V AC, making it suitable for various industrial applications. It can handle an impressive normal-duty current of 77 amps, ensuring stable performance in demanding environments.

Constructed with an IP20-rated enclosure, this drive meets the NEMA Type 1 standards, making it appropriate for interior installation where protection from dust and moisture is moderate. It is equipped with a blank cover, meaning it does not feature an operational human-machine interface.

The model lacks a braking system but includes an adjustable bus undervoltage trip, allowing users to set specific thresholds to enhance operational safety. Monitoring is facilitated via a heat sink thermistor, controlled by a microprocessor, to detect overheating and ensure reliable function.

In terms of operational resilience, the 20DD077A0NNNAENNN includes a logic control ride-thru feature, maintaining power for 0.25 seconds when not actively running. Additionally, it can manage brief power interruptions with a power ride-thru capability lasting for 15 milliseconds at full load, ensuring consistent operation during transient events. Overall, the 20DD077A0NNNAENNN is engineered for robust motor control and operational reliability in industrial settings.
