The reactor is connected in series with the input of the speed controller.

• It eliminates the voltage pulses coming from the mains and ensures the long life of the driver.
• Thanks to the 2-4.6V voltage drop it provides, it protects the driver against the high voltage risk that may come from the mains.
• It destroys the harmonies produced by the driver and protects the system.
• It prevents sudden current changes and protects the driver.
• It saves energy.
