The Allen-Bradley 20DD385A3ENNBRANE is an adjustable-frequency AC drive that operates at 480V AC. Designed for robust three-phase applications, this model supports a maximum normal-duty current rating of 385 amps. The unit has an enclosure rated IP20, providing adequate protection in indoor environments according to NEMA Type 1 specifications.
This product features a full numeric LCD human-machine interface, which allows for easy access to vital operational information and settings adjustments. Unlike many other models, this drive does not include a braking feature.
Safety and performance are foremost, and the 20DD385A3ENNBRANE incorporates an adjustable bus undervoltage trip that enhances reliability. A microprocessor monitors the heat sink thermistor, allowing the system to respond to thermal conditions effectively. Furthermore, the drive provides logic control ride-thru for up to 0.25 seconds when not actively running, and it can sustain power ride-thru conditions for 15 milliseconds at maximum load. This combination of design and features makes the 20DD385A3ENNBRANE a suitable solution for demanding industrial applications.
