The Allen-Bradley 20DD460A3ENNBRNBN adjustable frequency AC drive is designed specifically for robust performance in industrial applications. With a voltage rating of 480 volts AC, it supports three-phase configurations efficiently. This device has a maximum input capacity of 460 amps, making it suitable for demanding power needs.
Enclosed in a NEMA Type 1 rated IP20 housing, the drive safeguards its electrical components from dust while allowing easy access for installation and maintenance. Users can interface with the unit through a full numeric LCD that provides essential operational data and makes navigation straightforward.
This model does not incorporate a braking system. Instead, it features an adjustable bus undervoltage trip, which allows for operational customization based on specific requirements. The internal heat sink thermistor is actively monitored by a microprocessor to prevent overheating by triggering a trip if necessary.
In terms of operational stability, the drive offers a logic control ride-thru capability of 0.25 seconds when the unit is not in operation. Furthermore, it provides a power ride-thru ability for 15 milliseconds when under full load, ensuring consistent operation during brief power interruptions. The 20DD460A3ENNBRNBN is a versatile solution for varying operational demands in industrial settings.
