20DE820A0ENNBNCNK

The 20DE820A0ENNBNCNK model is part of the Allen-Bradley PowerFlex 700S series and serves as a highly capable adjustable frequency AC drive. It is designed to function at an input voltage of 600V AC, making it well-suited for three-phase setups in an industrial context. The unit is rated for an impressive input current of 820 amps, supporting high-performance applications that require significant power.

With an IP20-rated enclosure, corresponding to NEMA Type 1 standards, the drive is protected from dust and contact hazards, facilitating reliable performance in factory environments. Users will find a blank cover in place of a human interface, allowing for alternative control methods. A quick start guide is provided to assist with initial configuration and deployment.

The drive does not have a built-in braking system but features an adjustable bus undervoltage trip to enhance operational safety. For thermal management, the heat sink thermistor is monitored by a microprocessor that can initiate an overtemperature trip if necessary, ensuring that the device operates within safe limits. The logic control mechanism enables the drive to endure brief power outages, providing a ride-thru duration of 0.25 seconds when inactive. Furthermore, it supports a power ride-thru capability of 15 milliseconds while under full load conditions, ensuring continued functionality during temporary disruptions.
