20DD300N0ENNBNNNN

Designed for robust performance, the part number 20DD300N0ENNBNNNN from Allen-Bradley functions as an adjustable frequency AC drive. This unit is suitable for three-phase applications and operates effectively at a voltage level of 480 volts AC. It can support up to 300 amps of normal-duty current, which is ideal for managing demanding loads in industrial settings.

The drive is encased in an enclosure rated IP20 and complies with NEMA Type 1 standards, ensuring protection from solid contaminants. It features a blank cover instead of a display, indicating a streamlined design for integration into various control systems.

Unlike some other drives, this model does not include a braking system. However, it does come equipped with an adjustable bus undervoltage trip feature, allowing for customized operational parameters. It also incorporates a heat sink thermistor that is actively monitored by a microprocessor, ensuring that the unit remains within safe temperature limits. This promotes operational reliability and longevity.

In terms of protective features, the 20DD300N0ENNBNNNN supports logic control ride-thru for up to 0.25 seconds while the drive is not actively running, preventing loss of configuration. Additionally, it provides a power ride-thru capability for 15 milliseconds at full load, offering a buffer against momentary power interruptions. Overall, this drive is designed for efficiency and stability in various industrial applications.
