20DD125A3NNNA1NNA

The part number 20DD125A3NNNA1NNA, a component of the Allen-Bradley PowerFlex 700S lineup, functions as an adjustable frequency AC drive. It is engineered to handle three-phase electrical applications at a nominal voltage of 480V AC. This drive can sustain an input current rating of 125 amps, making it suitable for various industrial settings.

Constructed within an IP20 enclosure that complies with NEMA Type 1 requirements, this drive is designed to protect against the ingress of dust and solid objects while remaining safe for indoor use. The human interface comprises a full numeric LCD, facilitating user interaction and settings monitoring, although this component lacks accompanying documentation.

The unit does not feature a braking mechanism but compensates with an adjustable bus undervoltage trip, allowing users to set thresholds tailored to their systems. Additionally, a heat sink thermistor, monitored by a microprocessor, offers protection against overheating by engaging an overtemperature trip.

For operational resilience, the drive includes a logic control ride-thru capability of 0.25 seconds when the drive is not actively running, ensuring uninterrupted functionality during brief power disturbances. Additionally, the power ride-thru feature can maintain operation for up to 15 milliseconds under full load, which aids in preserving system integrity during voltage fluctuations.
