AC Variable Frequency Inverters
Hitachi manufactures a complete family of AC Variable Frequency Inverter induction motor drives below 500hp. Variable Speed Drives save energy by reducing power consumed by motors driving centrifugal pumps, fans and other rotating equipment. By controlling the speed of a motor, the amount of energy used by the machinery is optimized. Reduced energy use translates to reduced carbon (CO2) emissions.
Five major product families cover a wide array of applications in the industrial, process, and commercial HVAC markets. Hitachi inverters offer compact size, high level functionality including Intelligent Sensorless Vector Control with built-in communications in sizes up to 500HP. Hitachi inverters include 115V single phase, 230V and 460V 3-phase ratings.
