The Allen-Bradley 20G11NC037JA0NNNNN PowerFlex 755 AC drive stands out in the PowerFlex 750 series for its exceptional motor control capabilities in diverse applications with precise torque and speed requirements. Designed for both closed-loop and open-loop regulation, it supports advanced positioning with features like PCAM, indexer, and gearing applications, ensuring high performance and control. Operating with a 400 Volt AC (3-phase) or 540 Volt DC input and a robust 18.5-kilowatt output, this drive provides a 97.5% efficiency at full load and incorporates BUS overvoltage protection along with programmed current limiting. Its advanced safety features such as Safe Torque-Off and Safe Speed Monitor, accessible through hardwired and networked options, enhance operational safety while reducing costs. Flexibility is further bolstered by its slot-based architecture supporting up to five option cards tailored for feedback, communication, and additional power and safety functions, all within a NEMA open enclosure suitable for 0 to 50 degrees Celsius operating conditions.
