The 20DD460A0ENNBNASE, developed by Allen-Bradley of Rockwell Automation, functions as an adjustable-frequency AC drive. It operates effectively within three-phase electrical systems at a voltage level of 480V AC. It is rated to handle 460 amps of normal-duty current, making it capable of supporting higher-power applications effectively.
This drive is housed in an IP20-rated enclosure and conforms to NEMA Type 1 standards, designed to provide basic protection in less demanding environments. It has a protective blank cover instead of an integrated user interface. Notably, this model does not feature an integrated braking system. The drive includes an adjustable bus undervoltage trip feature, allowing users to set specific operational parameters.
For thermal management, the heat sink is monitored by a built-in microprocessor, which initiates a trip in case of overheating situations. Additionally, the logic control ride-thru period lasts for 0.25 seconds when the drive is not actively operating, preventing abrupt shutdowns during brief power outages. The device is also capable of maintaining a power supply for up to 15 milliseconds at full load, ensuring continued operation during short interruptions.
