£59,876.00
The Danfoss 137G1990 is a powerful iC7-Automation regenerative Active Front End (AFE) system module designed for high-power industrial drive systems requiring energy regeneration, advanced grid performance and seamless integration. As part of the innovative Danfoss iC7-Automation series, this air-cooled system module combines exceptional power density, embedded cybersecurity and intelligent control capabilities for demanding industrial environments.
Developed for OEMs, machine builders and industrial automation specialists, the iC7-Automation platform delivers reliable operation, flexible communication options and Industry 4.0 readiness. The regenerative AFE architecture allows energy generated during braking and deceleration to be returned to the electrical supply, helping improve overall system efficiency and reduce operating costs.
With a nominal AC current of 1664 A at 400 V AC and operation from a three-phase 380-500 V AC supply, the Danfoss 137G1990 is ideally suited to large-scale industrial automation, material handling systems, process plants and high-power machinery. Its modular design enables straightforward integration into advanced drive systems and common DC bus installations.
The Danfoss iC7-Automation regenerative AFE platform is designed to provide outstanding shaft and grid performance while supporting efficient energy management. During motor braking or overhauling loads, energy can be fed back into the electrical network rather than dissipated as heat, helping reduce energy consumption and cooling requirements.
Its modular architecture and embedded Industrial IoT security make the 137G1990 suitable for large-scale industrial systems where reliability, efficiency and connectivity are critical. The platform supports modern automation networks and future-ready digital manufacturing environments.
