The Danfoss 137U4112 is a high-power iC7-Automation frequency converter designed for reliable control of large three-phase AC motors in demanding industrial environments. As part of the advanced Danfoss iC7-Automation drive platform, it delivers precise motor speed regulation, efficient operation and flexible integration into modern automation systems.
This air-cooled variable speed drive is engineered for industrial applications where uptime, safety and communication capability are essential. Its IP54 / UL Type 12 enclosure provides enhanced protection for installations that require greater resistance to dust and environmental exposure than open-panel drive formats.
With a rated output current of 736 A and a three-phase 380-500 V AC supply, the Danfoss 137U4112 is suitable for high-power motor applications including pumps, fans, compressors, conveyors, processing machinery and infrastructure systems.
Frequency converters such as the Danfoss 137U4112 regulate motor speed by adjusting output voltage and frequency. This allows industrial motors to operate more efficiently while improving process stability, reducing mechanical stress and supporting smoother machine operation.
The iC7-Automation platform is developed for modern industrial facilities where reliable operation, diagnostics, safety and digital connectivity are critical. With Modbus TCP communication, integrated Ethernet and STO functionality, this drive is well suited to high-power automation and process control systems.
