RC circuit (Resistive +capacitor) is an effective protection for circuits highly sensitive to "high frequency" interference. For use only in cases where the voltage is virtually sinusoidal. i.e. less than 5% total harmonic distortion. Voltage limited to 3 Uc max. And oscillating frequency limited to 400 Hz max. Slight increase in drop-out time (1.2 to 2 times the normal time).
