20DD500A3NNNBNGNE

The 20DD500A3NNNBNGNE, developed by Allen-Bradley, is part of the PowerFlex 700S series. This adjustable frequency AC drive is designed to function in three-phase electrical systems, operating effectively at 480V AC. With a substantial input capacity of 500 amps, it is well-suited for various industrial applications requiring robust performance and reliability.

This drive is contained within an IP20-rated enclosure that conforms to NEMA Type 1 standards, providing basic protection suitable for indoor environments. The human-machine interface utilizes a full numeric LCD, which facilitates easy monitoring and adjustments during operation.

While this model does not incorporate a braking system, it provides an adjustable bus undervoltage trip feature, allowing users to customize safety settings based on specific operational requirements. A heat sink thermistor is also integrated, monitored continuously by a microprocessor to offer overtemperature protection, ensuring the drive operates within safe thermal limits.

For operational resilience, the 20DD500A3NNNBNGNE supports a logic control ride-thru capability lasting 0.25 seconds when the drive is inactive. Additionally, its power ride-thru functionality supports up to 15 milliseconds at full load, allowing for continuous operation during brief electrical disturbances. This unit exemplifies reliability and efficiency for demanding motor control applications.
