S3: Dahili ve harici voltaj reg\u00fclat\u00f6r\u00fc ar\u0131zalar\u0131 aras\u0131ndaki fark nedir?<\/strong><\/p>\n

Dahili reg\u00fclat\u00f6rler alternat\u00f6r g\u00f6vdelerine entegre edilerek ar\u0131za te\u015fhisini daha karma\u015f\u0131k hale getirir ancak kablo ar\u0131za noktalar\u0131n\u0131 azalt\u0131r. Dahili reg\u00fclat\u00f6r ar\u0131zalar\u0131 tipik olarak komple alternat\u00f6r de\u011fi\u015fimi gerektirir ve i\u015f\u00e7ilik dahil $300-600'e mal olur, ancak baz\u0131 tasar\u0131mlar reg\u00fclat\u00f6r mod\u00fcl\u00fcn\u00fcn $100-200'e de\u011fi\u015ftirilmesine izin verir. Harici reg\u00fclat\u00f6rler \u00f6zel kablolama ile ayr\u0131 olarak monte edilir ve $75-150 i\u00e7in ba\u011f\u0131ms\u0131z test ve de\u011fi\u015ftirme sa\u011flar.<\/p>\n

Harici \u00fcniteler titre\u015fim ve konnekt\u00f6r korozyonu nedeniyle daha y\u00fcksek ar\u0131za oranlar\u0131 sergiler ancak daha kolay diyagnostik eri\u015fim sunar. Ar\u0131za belirtileri ince farkl\u0131l\u0131klar g\u00f6sterir: dahili reg\u00fclat\u00f6r ar\u0131zalar\u0131 genellikle yatak g\u00fcr\u00fclt\u00fcs\u00fc veya f\u0131r\u00e7a a\u015f\u0131nma g\u00f6stergeleri ile ortaya \u00e7\u0131karken, harici \u00fcniteler belirgin kablo demeti sorunlar\u0131 ve konekt\u00f6r terminali korozyonu g\u00f6sterir.<\/p>\n
