Nyt on p\u00e4\u00e4sty testailemaan ESR-mittari protolevy\u00e4. Mittari on k\u00e4tev\u00e4 kapinen elektrolyyttien mittaamiseen onko ne kunnossa. Mittari koostuu 2×16 LCD n\u00e4yt\u00f6st\u00e4, PIC prossusta ja OP vahvistimista.<\/p>\n

Konkassa on kahta resistanssia ESR ”Equivalent Series Resistance” sarjavatus ja ERP ”Equivalent Parallel Resistance” Rinnakkais vastus. Rinnakkas vastus ERP vaikuttaa konkan vuotovirtaan. Mit\u00e4 huonompi eli pienempi on vastus sit\u00e4 enemm\u00e4n konkka vuotaa ja aiheuttaa lyytin l\u00e4mpenemist\u00e4. Mutta emme nyt k\u00e4sittele t\u00e4t\u00e4 ominaisuutta. ESR sarjavastus kuvaa sit\u00e4 miten paljon se vastustaa virtaa. Mit\u00e4 isompi on vastus niin sit\u00e4 enemm\u00e4n se l\u00e4mmitt\u00e4\u00e4 lyytti\u00e4 ja aiheuttaa h\u00e4vi\u00f6it\u00e4. Siksi hakureissa pyrit\u00e4\u00e4nk\u00e4ytt\u00e4m\u00e4\u00e4n Low ESR konkkia joiden sis\u00e4inen vastus on joitain 0.070 – 0.010 Ohm luokkaa. T\u00e4h\u00e4n vaikuttaa tietenkin konkan kapasitanssin suuruus. Pit\u00e4 isompi sit\u00e4 pienempi ESR arvo. Lyytin ESR vaikuttaa fyysinen koko my\u00f6s ja miten laadukkaasti se on tehty. Pienempi koko niin se kasvattaa my\u00f6s sarjavastsuta. Normaalisti voi pit\u00e4\u00e4 85 asteen konkat on paljon huonompia kuin 105 asteiset. Mit\u00e4 korkeampi k\u00e4ytt\u00f6l\u00e4mp\u00f6tila niin sit\u00e4 pitempi on kestoik\u00e4, mutta t\u00e4h\u00e4nkin on poikkeuksia paljon koska kiina laatua on monenlaista. Ei aina kerro totuutta, ja siksi nyky\u00e4\u00e4n taulu telkut hajoaa ja suurin syy on huonot lyytit jotka ei kest\u00e4 l\u00e4mp\u00f6\u00e4 ja n\u00e4in ollen ne kuivaa. Siit\u00e4 taasen seuraa pahimmassa tapauksessa oikosulku ja joskus jopa palovaara.<\/p>\n

Joten t\u00e4ll\u00e4 nyt tekem\u00e4ll\u00e4ni proto ESR Mittarilla voidaan mitata t\u00e4ll\u00e4si\u00e4 lyyttej\u00e4. Mittari ilmottaa konkan koon ja my\u00f6s sarjavastuksen. Mittausalue on aina 10 ohm koska sen ylimenev\u00e4t saa heitt\u00e4\u00e4 heti kipperiin.<\/p>\n

T\u00e4ss\u00e4 oli jotain aloitettua ja jatketaan my\u00f6hemmin lis\u00e4\u00e4..<\/p>\n","protected":false},"excerpt":{"rendered":"
