Westek Electronics supplies the Schaffner RN series current compensated chokes suitable for lighting ballasts and power supplies in a wide range of lighting applications.
Schaffner RN series current compensated chokes find application in LEDs as well as low pressure and high pressure discharge lamps.
Schaffner RN series chokes meet the tough requirements of EN 55015, which limits conducted emission to 60 dBmV. The RN series chokes are also suitable for the suppression of radiated interference.
The current compensated chokes meet the tough standards of EN 61000-3-2 that imposes a limit of 30 dB (mV/metre) between 30 and 230 MHz at a distance of 10 metres.
Schaffner RN chokes can also be incorporated in effective mains filter designs, if the power supply or ballast does not readily meet emission standards. These filters can involve the use of X and Y capacitors.
Depending on circuit design, the Schaffner RN chokes can be highly effective when used directly without additional components.
