Frequency Inverters: Applications For Industrial Facilities

Reducing operational costs by operating machinery and building systems more efficiently is a goal for many industrial facilities. In some cases, facilities power certain buildings and electrical systems with renewable energy sources such as solar power or wind power. Considering the high number of electric motors and fluorescent lighting ballasts that industrial facilities have running at any given time, outfitting the motors with high-quality frequency inverters, and using power inverters (aka sine wave inverters) to refine the operation of lighting ballasts, can significantly improve energy usage and lead to better equipment performance.

Electric Motors

Electric motors that receive electricity from a Direct Current (DC) power source such as solar panels or wind turbines, and operate in response to data signals (eg cooling operations), can benefit from frequency inverters. In addition to refining the operation of motors by converting DC to Alternating Current (AC), the devices help motors operate more efficiently, serving as soft starters that reduce the amount of power that is required to start motors, and allowing motors to operate at the minimum frequency that is needed to get the job done.

Lighting Ballasts

Fluorescent lighting is an energy efficient technology. When an industrial facility receives an energy audit, the energy auditor often recommends replacing incandescent lighting and halogen lighting with incandescent lighting. However, for the replacement to make a significant difference in the facility's electric bill, fluorescent lighting ballasts must receive sinusoidal current that true sine wave inverters provide.

The devices can improve the performance of lighting ballasts when the later receive electricity from a source that produces Direct Current, and when the ballasts demonstrate signals of harmonic distortion, such as flickering bulbs and a distinct buzzing sound, regardless of the cause.

Lighting ballasts are not the only devices that perform better when they receive sinusoidal current, but their systematic implementation in industrial facilities makes them an ideal reason to outfit a building with devices that improve energy usage and equipment performance. Other devices the benefit from receiving sinusoidal current include sensitive computer equipment, sound equipment, and digital devices.


Using frequency inverters and sine wave inverters to improve the performance of electric motors and lighting ballasts that receive power from renewable energy sources help facilities improve energy usage and refine the performance of the equipment.
