Grizzly Posted December 13, 2018 Share Posted December 13, 2018 Would this unit possibly be a good basis for a DIY power filter/conditioner thingy? https://www.oeelsafe.com.au/surge-protection-single-phase-filter/ All I want to know is whether it would be effective, not warnings about 240v, danger, bad thing, ouchy burny. I'm not stupid enough to attempt it myself. Link to comment Share on other sites More sharing options...
pete_mac Posted December 13, 2018 Share Posted December 13, 2018 I think it comes down to what issues you are trying to address, and whether you need the MOVs for surge protection. I'm contemplating one of these - @andyr uses them in his dooverlackeys from memory: https://au.element14.com/schaffner/fn2090-10-06/filter-1-ph-10a-chassis-mount/dp/1304861 Link to comment Share on other sites More sharing options...
Thekman76 Posted December 13, 2018 Share Posted December 13, 2018 They both do filtering but the Schaffner is filter focused, where the OE Electrics is focused on surge protection. In answer to the OP, it appears to be all passive components so I don't see it doing any harm. You're unlikely to introduce any noise with these components so I don't see a reason not to. Beyond that I don't have any evidence that either will improve anything. Link to comment Share on other sites More sharing options...
HdB Posted December 13, 2018 Share Posted December 13, 2018 I've used the Schaffners for some years but I think these 'oeelsafe' ones have a similar inline filtering plus added surge protection - I would presume these aren't a cheap little board ...?

Beyond that I don't have any evidence that either will improve anything. My experiments a few years ago showed that they, indeed, did improve the sound - particularly, for source components, when used in conjunction with an isolating transformer. At the very least, a hash filter will stop crap produced by the SMPS in a component like a DVD player, from being injected back into the mains and "polluting" other components. It also stops crap which is already in the mains - produced by other things in your house (like TVs, Foxtel boxes, modems, computer PSs, LED lights, subs, solar power inverters - the list is endless! ) - from polluting a component which has a linear PS.

Guest Posted December 13, 2018 Share Posted December 13, 2018 The reason I cottoned on to these units is because my workplace use them in the control switchboards for CO2 refrigeration plant. I asked and was told that they filter/reject the hash and EMF etc- these systems apparently require a clean supply to operate optimally. They're not cheap, around $320 but if the outcome is similar to a commercial product costing 1k or more it may be an interesting road to head down. Hard wire a power lead and a quality multi socket board and away you go! Link to comment Share on other sites More sharing options...
