20DD125A0NNNA6CNL

The part number 20DD125A0NNNA6CNL is a robust adjustable frequency AC drive offered by Allen-Bradley. This particular model operates efficiently at an input voltage of 480V AC and is suitable for three-phase systems. The drive is rated for handling input currents up to 125 amps, making it capable of supporting demanding applications requiring significant power. Encapsulated in an IP20-rated enclosure according to NEMA Type 1 standards, the design ensures basic protection against solid objects, while permitting indoor use. However, it features a blank cover that indicates it lacks a conventional human-machine interface.

This drive does not integrate a braking system. Nonetheless, it provides critical safety functionalities such as an adjustable bus undervoltage trip, giving users flexibility to customize operational parameters. Additionally, the heat sink thermistor is actively monitored by a microprocessor, providing precise control over temperature management to prevent overheating.

As for functionality during power interruptions, the device features a logic control ride-thru capability lasting 0.25 seconds when inactive. This ensures continuity in control processes during brief outages. Furthermore, the power ride-thru capability allows it to maintain operation for 15 milliseconds under full load conditions. Overall, the 20DD125A0NNNA6CNL serves as a capable option for various industrial applications where reliable motor control and safety are paramount.
