Inovance HD9x is a modern high-performance industrial frequency inverter with vector control designed to work with asynchronous and synchronous motors up to 12.5MVA. Series connection of power cells allows to obtain a maximum output voltage of 13.8kV. HD9x has advanced control functions and high reliability. HD9x inverters meet energy saving and speed control requirements for general purpose machines such as large and medium sized fans and pumps.
Typical applications for HD9x inverters include power generation, metallurgy, petrochemical, mining, cement, pulp and paper industries and urban infrastructure.
