The Allen Bradley 20DD077A0NNNANASE functions as a high-performance AC drive tailored for complex control systems. Supporting a voltage rating of 480 Volts AC, this drive operates with an output current capacity of 77 amperes, making it effective for various industrial applications. Its horsepower ratings reach 50 for heavy-duty scenarios and 60 for normal operations.
This drive is designed for a 3-phase input arrangement and operates under a 6-pulse configuration. Feedback mechanisms include a second encoder, enhancing performance monitoring and control accuracy. Please note, however, that this model features a blank cover and lacks a human-machine interface, resulting in a straightforward design focused on efficient operation without extraneous controls.
Frame size designation is categorized as frame size 4, ensuring compatibility with various installation environments. The ambient temperature for operational use ranges from 0 to 40°C, and it is capable of being stored in temperatures between -40 and 70°C, given that a non-condensing atmosphere is maintained. Notably, this drive does not contain a braking unit.
With an IP20 rating, conforming to NEMA Type 1 standards, it offers reasonable protection against dust and incidental contact. Additionally, the drive's design incorporates an emission class that uses a CE filter and common mode choke, contributing to overall energy management and electromagnetic compatibility.
