£59,000.00
The Danfoss 137G1991 is a high-performance iC7-Automation regenerative Active Front End (AFE) system module engineered for demanding industrial drive applications requiring efficient energy regeneration, advanced grid performance and seamless automation integration. As part of the innovative Danfoss iC7-Automation series, this air-cooled system module delivers exceptional power density, embedded cybersecurity and intelligent control functionality for modern industrial environments.
Developed for OEMs, machine builders and industrial automation specialists, the iC7-Automation platform combines reliability, flexibility and Industry 4.0 readiness. The regenerative AFE architecture enables energy generated during braking and deceleration to be returned to the electrical supply network, helping reduce energy consumption and operating costs while improving overall system efficiency.
Operating from a three-phase 380-500 V AC supply, the Danfoss 137G1991 is ideally suited to high-power automation systems, material handling equipment, process industries and common DC bus drive architectures. Its modular cabinet integration design enables flexible installation in demanding industrial applications.
The Danfoss iC7-Automation regenerative platform is designed to optimise energy efficiency in industrial drive systems. During motor braking or overhauling conditions, energy can be returned to the electrical network rather than dissipated through braking resistors, helping reduce heat generation and improve overall system performance.
Its intelligent architecture combines advanced connectivity, integrated security and scalable functionality, enabling engineers to deploy highly efficient drive systems while maintaining flexibility for future expansion and digitalisation initiatives.
