20DD077A0NYNANDNK

The 20DD077A0NYNANDNK adjustable frequency AC drive is part of the Allen-Bradley PowerFlex 700S series. It functions effectively within a range of industrial applications, operating at 480V AC in a three-phase setup. Capable of managing a normal-duty current of 77 amps, this drive is built to accommodate significant load demands.

This model features an enclosure that is compliant with IP20 and NEMA Type 1 specifications, ensuring adequate protection during standard usage scenarios. The device includes a blank cover for its human-machine interface, offering a straightforward configuration with minimal external controls.

Equipped with IGBT braking for enhanced operational efficiency, the drive includes an adjustable bus undervoltage trip, which allows customization based on specific operational parameters. Additionally, it is integrated with a heat sink thermistor monitored by a microprocessor to safeguard against overheating, which can trigger an automatic over-temp trip to protect the drive’s integrity.

The device provides a logic control ride-thru capability of 0.25 seconds during non-operational periods, promoting stability in case of brief interruptions. Furthermore, under full load conditions, it maintains power ride-thru support for up to 15 milliseconds, ensuring reliability in dynamic electrical environments. Overall, the 20DD077A0NYNANDNK is a robust solution tailored for diverse industrial motor control applications.
