Solutions for renewable energy systems

LEM transducers, specifically designed for renewable power systems, control the flow and waveform of energy sent to the grid from renewable energy systems. They measure the current to help the windmills, solar, photovoltaic or any kind of installations to work at their maximum efficiency.


Main applications for Renewable Energies

Smart and efficient use of renewable energies

The use of power electronics is a must to drive and control energy from the renewable sources in the most energy efficient way. Modern systems require precise coordination between the power semiconductors, the system controller, mechanics and the feedback sensors. Current sensors provide the necessary information from the load to fulfill that function.

Typical applications for Renewable Energies:

  • Solar
  • Windmills
  • Hydroelectric
  • Fuel cells
  • Geothermal power
  • Tidal energy
