20DD460N3NNNBCGNE

The 20DD460N3NNNBCGNE model is an adjustable frequency AC drive offered by Allen-Bradley. Built for reliable performance at a voltage of 480V AC, this device is configured for three-phase applications and capable of accommodating an input current of up to 460 amps. This drive is designed to operate efficiently within demanding industrial settings where high performance is essential.

The unit features an open type enclosure, rated IP00, ensuring versatility in various mounting conditions. Although there is no accompanying documentation, users can easily operate the drive via the full numeric LCD human interface. This feature simplifies monitoring and adjustment of the drive's settings, allowing for straightforward operational control.

This model does not include a braking system, but it compensates with an adjustable bus undervoltage trip that enhances safety and protects against voltage fluctuations. Overtemperature conditions are monitored through a heat sink thermistor that's overseen by a microprocessor, ensuring reliable thermal management. Additionally, the drive supports logic control ride-thru functionality for 0.25 seconds when idle, thereby maintaining stability during brief power losses. Further reinforcing its reliability, the power ride-thru feature allows operation for up to 15 milliseconds at full load, providing continued performance during temporary interruptions.
