20DD46023ENNBRNNN

The 20DD46023ENNBRNNN adjustable frequency AC drive by Allen-Bradley is designed to meet the rigorous demands of industrial applications. Rated for 480 volts AC, it operates effectively within a three-phase setup. With a maximum normal-duty current capability of 460 amps, this drive ensures robust performance in applications requiring substantial power handling.

Housed in an IP20-rated and NEMA Type 1 compliant enclosure, the drive is suitable for indoor use where protection from dust and moisture is needed. The design does not include a standard human-machine interface, offering instead a blank cover to simplify installation and integration into existing systems.

Notably, this unit does not feature a braking system. However, it compensates for potential voltage drops with an adjustable bus undervoltage trip setting. For thermal management, the drive is equipped with a heat sink thermistor, which is constantly monitored by a microprocessor to safeguard against overheating conditions.

For operational stability, this drive offers logic control ride-thru capabilities that allow the system to maintain settings for up to 0.25 seconds while inactive. Additionally, it is designed to sustain power ride-thru for a short duration of 15 milliseconds during full load conditions, ensuring reliable operation even during brief interruptions. The combination of these features makes the 20DD46023ENNBRNNN a dependable solution for industrial applications requiring precision and control.
