20DD248A0NYNANANL

The 20DD248A0NYNANANL is classified as an adjustable frequency AC drive and is produced by Allen-Bradley, part of Rockwell Automation. Equipped to function in a 3-phase environment, it operates efficiently at 480V AC. The normal-duty current can reach as high as 248 amps, making it suitable for applications that require significant power.

The drive's enclosure is rated IP20, meeting the requirements of NEMA Type 1 standards and ensuring protection against dust and solid objects when used indoors. Its human-machine interface consists of a blank cover, providing a streamlined appearance but lacking a display.

This unit features an IGBT braking system for effective operation, which enhances control of the motor dynamics. An adjustable bus undervoltage trip increases safety by allowing configuration based on the specific needs of the setup. Additionally, a heat sink thermistor monitored by a microprocessor is included to prevent overheating, triggering an overtemperature trip as necessary.

The unit also contains logic control ride-thru functionality that allows for a duration of 0.25 seconds when the drive is not running, ensuring operational stability during brief interruptions. Moreover, the system is designed to maintain power ride-thru for 15 milliseconds while under full load, providing reliable performance even in volatile environments.
