20DD125A0NYNA1CNL

The 20DD125A0NYNA1CNL is an adjustable frequency AC drive produced by Allen-Bradley, belonging to the PowerFlex 700S series. This unit is designed to operate at a voltage of 480 volts AC and is configured for three-phase systems. It is capable of managing input currents up to 125 amps, making it suitable for various demanding applications.

The construction of this drive features an enclosure rated IP20, compliant with NEMA Type 1 guidelines, ensuring its suitability for indoor installation where exposure to particulates is limited. Notably, the human-machine interface of this model is a blank cover, indicating minimal interactive features, which also means no accompanying operational documentation.

The drive is equipped with an IGBT-based braking mechanism that enhances its operational efficiency. Additionally, it provides an adjustable trip for bus undervoltage conditions, allowing for tailored settings to fit particular operational parameters. To monitor thermal conditions, the heat sink thermistor is tracked by a microprocessor, which provides safeguards to prevent overheating through automatic intervention.

In terms of operational resilience, the unit enables a logic control ride-thru feature that lasts for 0.25 seconds when the drive is not running. Furthermore, it supports power ride-thru functionality enabling it to maintain performance for 15 milliseconds at full load, ensuring system stability during temporary power fluctuations. Overall, the 20DD125A0NYNA1CNL is engineered to provide effective motor control in a range of industrial settings.
