The Danfoss 137U0645 is a high-performance iC7-Automation enclosed variable frequency drive designed for demanding industrial motor control applications. Built on the advanced Danfoss iC7-Automation platform, this air-cooled enclosed drive provides precise speed regulation, regenerative capability and dependable integration for large three-phase AC motors.
This drive is engineered for industrial environments where efficient motor control, low harmonic impact and reliable automation connectivity are essential. The Danfoss 137U0645 combines regenerative active front end drive technology with Modbus TCP communication, integrated cabinet protection and a robust enclosed format for modern process and automation systems.
With a rated output power of 355 kW / 500 HP, a 658 A current rating and a three-phase 380–500 V AC supply, the 137U0645 is suitable for high-power motor applications. Its IP21 / UL Type 1 enclosure supports protected indoor installation in electrical rooms, motor control centres and industrial control environments.
Variable frequency drives such as the Danfoss 137U0645 regulate motor speed by adjusting the frequency and voltage supplied to the motor. This enables smoother operation, improved process control and reduced energy consumption compared with fixed-speed motor systems.
The regenerative active front end design allows braking or overhauling energy to be returned to the supply network, improving efficiency in suitable applications. With Modbus TCP connectivity, enclosed cabinet construction and high-power motor control capability, the 137U0645 is well suited to demanding industrial automation and process control installations.
