The part number 20DD125A3NNNACNNN represents an adjustable frequency AC drive manufactured by Allen-Bradley, part of the Rockwell Automation family. Operating at a voltage level of 480V AC, this unit is ideal for three-phase installations and is rated for an input current of 125 amps. This drive ensures compatibility and robust performance in diverse industrial environments.

Its enclosure is rated at IP20, adhering to NEMA Type 1 standards, which protects internal components from dust and direct contact. The drive features a full numeric LCD, facilitating user interaction, but notably, it lacks accompanying documentation.

The absence of a brake system in this model is offset by its adjustable bus undervoltage trip feature, which allows customization based on specific usage requirements. Furthermore, thermal management is addressed through a heat sink thermistor, which is monitored by a microprocessor to prevent overheating and ensure safe operation.

In terms of operational reliability, the drive provides a logic control ride-thru capability lasting 0.25 seconds when not engaging. During high-load conditions, it is equipped with power ride-thru functionality for 15 milliseconds, ensuring consistent performance even during temporary disturbances in power supply.
