Hi all,
I am planning to designSMPS circuit. In that for input protection I am using 275 varistor after the fuse. but one of my friend told we need to place the varistor before the fuse. Any one can please suggest where we need to place the varistor exactly and what will happen if we are placing the varistor before the fuse?
Please find the attached Images for reference
Image having two varistor RV1 and RV2 which one is correct
Thanks in advance
