20DD500BCENNBNANE

The 20DD500BCENNBNANE is an adjustable frequency AC drive manufactured by Allen-Bradley and part of the PowerFlex 700S series. This drive is designed to operate at a voltage of 480V AC, making it suitable for a variety of industrial applications. It is configured for use in three-phase power systems and can handle input currents of up to 500 amps, ensuring it meets robust power requirements.

Constructed within an enclosure rated at IP20 and NEMA Type 1, the drive features a conformal coating that provides enhanced protection against environmental factors. The human-machine interface is designed with a blank cover, which may contribute to a simplified design. Documentation is provided in the form of a quick start guide to facilitate setup and operation.

A notable aspect of the 20DD500BCENNBNANE is the absence of a built-in braking system. However, it includes an adjustable bus undervoltage trip, providing a customizable safety feature. Additionally, the heat sink thermistor is monitored by a microprocessor to detect overheating conditions, ensuring reliability and performance during operation.

The drive supports a logic control ride-thru for a maximum of 0.25 seconds when it is not actively running, allowing it to maintain essential settings during brief power outages. For added stability, this device also supports power ride-thru for up to 15 milliseconds under full load. This combination of features illustrates the drive's design for efficiency and safety in industrial applications.
