As can be seen, this LSP05240 Mains Surge module lets through up to 1100V of ‘residual’ voltage.
Obviously, the surge module has to go upstream of the AC mains filter in the SMPS. As such, would you agree that when the 1100v of “residual voltage” hits the AC input LC filter of the SMPS, then the voltage at the output of the diode bridge will actually be 2200V?
We are trying to protect against this and believe that a TVS after the bridge rectifier is the way, would you agree?
