20DD125A3ENNANNNN

The 20DD125A3ENNANNNN represents an adjustable frequency AC drive from Allen-Bradley, part of the PowerFlex 700S series, aimed at providing reliable motor control. With a maximum operating voltage of 480V AC, it is engineered for three-phase applications, handling a substantial input current of 125 amps efficiently. This drive's design includes an enclosure classified as IP20 in accordance with NEMA Type 1, suitable for indoor use where moderate protection against dust and contact is required.

An intuitive full numeric LCD serves as the human-machine interface, allowing easy monitoring and adjustments during operation. Each unit comes with a quick start guide to facilitate installation and setup for users. Notably, this model does not have a braking feature.

Safety and operational stability are critical aspects of the design; hence, it features an adjustable bus undervoltage trip setting. This flexibility allows users to set parameters suited to their specific operational requirements. Thermal management is another key feature of the unit, achieved through a heat sink thermistor that is actively monitored by a microprocessor, which will trigger an overtemperature trip as necessary to safeguard functionality. Additionally, the drive is capable of sustaining logic control ride-thru for 0.25 seconds during non-operation, alongside power ride-thru support of 15 milliseconds at full load, ensuring reliability during power fluctuations.
