AS800 high voltage inverter is an energy saving and environmental friendly IGBT variable frequency inverter designed based on international advanced electrical, electronic and vector control technologies. It offers superior motor control performance and great environmental adaptability, due to our efforts to make improvement on the high voltage inverter according to market demand. It is extensively used to control the speed of high voltage motors so as to achieve reduced energy consumption. The high voltage inverter has few requirements on electric motors and connection cables. So, an old machine can be controlled by the high voltage inverter without changing its electric motor.
The high voltage inverter is applicable for not only common loads like fans, pumps and conveyors, etc., but also equipment requiring high precision speed control and large starting torque, such as plastic and rubber processing equipment, food equipment, and more. To illustrate, our high voltage inverters have been widely used to drive different types of water pumps, fans, air compressors, and belt conveyors, etc. in industries and fields such as thermal power generation, water supply and water treatment, metallurgy, cement and porcelain, air conditioning, offshore drilling platform, and more. They are also widely used in plastic and rubber processing and food making industries to drive extruding machine, mixing equipment, grinding machine, and filtering equipment, etc. The high voltage inverter is also ideal for use in pharmaceutical industry, papermaking industry and testing labs to drive related equipment.
