starcat Posted May 9, 2021 Report Share Posted May 9, 2021 (edited) Using 282VA trafo (with [email protected] secondaries) divided by 230V line voltage * 133% gives me 1.63A for the fuse. As it is pretty much oversized, should opt for 1.5A or 2A fuse and should I combine it with a 1.6A (CL-130) or 1.7A (CL-120) termistor for inrush current protection, what is your take on this?

mwl168 Posted May 9, 2021 Report Share Posted May 9, 2021 I always use a thermistor for inrush current protection with my PSUs. If you use a thermistor I would try a 1A or even smaller fuse. You may have to experiment a bit based on the thermistor, filter caps of choice. 1 Quote Link to comment Share on other sites More sharing options...
starcat Posted May 9, 2021 Report Share Posted May 9, 2021 Thanks! I have used 4x 550V 680uF caps within a GRHV. Quote Link to comment Share on other sites More sharing options...
starcat Posted July 31, 2021 Report Share Posted July 31, 2021 Moving forward with the CFAE, drilled the bottom and completely mounted the toroid and GRHV. The C2M1000170D's are still missing. Probably I should replace them with the C3M0350120D. New front and back panels next. 2 Quote Link to comment Share on other sites More sharing options...
yabba235 Posted February 7, 2022 Report Share Posted February 7, 2022 I don't know if I'm looking wrong but I can't find a schematic for cfaelectrostatic, besides, there are no gerberas for this project either. Are they available somewhere? Quote Link to comment Share on other sites More sharing options...
kevin gilmore Posted February 7, 2022 Author Report Share Posted February 7, 2022 i found the synthesis file it is now posted in the documents directory cfaelectrostaticschem.pdf in the boards share there is cfaelectrostat.zip and electrostat2.zip there are other surface mount versions that have not been posted next time don't post twice, and you can always ask me 1 Quote Link to comment Share on other sites More sharing options...
