Our contractor is doing a 200W Offline SMPS (240VAC). He is putting the MOV directly after the mains input connector…then the fuse. This is because the MOV sinking surge current is not wanted to blow the fuse. If the MOV gets damaged it will blow up anyway…so there’s no point putting it downstream of the fuse, would you agree?
We just hope we are not violating some safety reg?
