Industry sectors

industriale automation icon

Industrial Automation

The range  of electric drives for speed control of AC, DC and brushless motors used in the most modern industrial automation systems.

HVAC icon

HVACR Market

HVACR means “Heating, Ventilation, Air Conditioning and Refrigeration”, and includes all heating, ventilation, air conditioning and cooling systems.

An AC drive is a device used to control the speed of an electric motor for:

  • Improve process control
  • Reduce energy use and generate energy efficiently
  • Reduce mechanical stress on motor control applications
  • Optimize the operation of various applications that depend on electric motors


Frequency converters can also be used to produce energy from natural and renewable resources such as the sun, wind or tides and to transmit it to the grid or to use it for local consumption.

In hybrid technologies, AC frequency converters are used to combine renewable energy sources and energy reserves to create total energy management solutions.

AC frequency converters are also known under other names such as variable speed drives, adjustable inverters, variable speed drives, frequency converters, inverters and power converters.
