This device raises the turn-on voltage threshold of the series combination against low frequency overvoltage conditions while having minimal impact on the voltage clamp level when subjected to a lightning surge. Using this series combination will prevent the MOV from conducting when line frequency voltage swells (up to the sum of the breakdown voltages of the two components) occur on the ac input lines of the power supply. This allows a design to avoid the use of a higher voltage MOV, which, if used, would significantly reduce the level of lightning protection. See the Application section for additional information.
