20DR125A3NNNACNNN

The 20DR125A3NNNACNNN, a component of the Allen-Bradley PowerFlex 700S series, is an adjustable frequency drive designed for demanding industrial applications. Set to operate at a substantial voltage level of 650V DC, this unit is capable of supporting a three-phase system with a maximum input current of 125 amps.

The design features an enclosure rated at IP20 and compliant with NEMA Type 1 standards. This assures reasonable protection against dust and solid objects while maintaining suitability for indoor applications. A full numeric LCD serves as the human interface for this drive, enabling users to access relevant information and configurations easily.

This model does not integrate a braking system, which may simplify its application in specific scenarios. For safety, it is equipped with an adjustable bus undervoltage trip function, allowing tailored operation according to user requirements. Its heat sink thermistor is actively monitored by a microprocessor, which triggers an overtemperature response if necessary, contributing to reliable temperature management.

The 20DR125A3NNNACNNN also provides a logic control ride-thru capability of 0.25 seconds when the drive is not actively running. Additionally, the unit can handle power ride-thru for a duration of 15 milliseconds while loaded, ensuring continuity during brief power disruptions. Overall, this drive combines an array of functional features and specifications tailored for robust industrial settings.
