As so some electronic devices and electric apparatus, the frequency of AC power should meet a certain requirement. When the power supply is higher or lower than 50 Hz, the devices’/apparatus’ performance would be influenced, and even destroyed. Therefore, power frequency detector should be assembled for those devices/apparatus. When the power supply is not within required range of variation, the detector will give out warning or cut off the power supply automatically to ensure the security of the devices/apparatus. The above picture is power frequency detector composed of CD4013, which will cut off the working power when the power frequency is beyond a certain range around 50Hz to ensure the security of devices/apparatus.
