20DD500N0ENNBNNNN

The 20DD500N0ENNBNNNN is part of the Allen-Bradley PowerFlex 700S series, providing adjustable frequency control for industrial applications. Rated for 480 volts AC, this drive efficiently handles three-phase systems, managing input currents up to 500 amps. The design features an open enclosure with an IP00 rating, allowing for effective installation in various environments without additional protective barriers.

A blank cover replaces traditional human-machine interface components, streamlining its overall footprint and reducing potential points of failure, although a quick start guide is provided to assist with setup. Notably, this drive does not include a built-in braking system, emphasizing its focus on consistent operational performance.

Among its safety features, the drive includes an adjustable bus undervoltage trip, which enhances its capability to adapt to different operational scenarios. Thermal management is addressed by a heat sink thermistor, monitored by a microprocessor that can initiate an overtemperature trip if needed. For operational stability during brief power interruptions, the drive maintains logic control ride-thru for 0.25 seconds while not actively running. Additionally, it supports power ride-thru for a duration of 15 milliseconds under full load conditions, ensuring reliable performance and minimizing downtime.
