Solid State relej (SSR)<\/strong> je elektronski prekida\u010d bez mehani\u010dkih delova. Umesto klasi\u010dnih kontakata, koristi poluprovodni\u010dke komponente<\/strong> (tiristore, trijake, MOSFET-e) za uklju\u010divanje i isklju\u010divanje elektri\u010dnog kola.<\/p>

Za razliku od klasi\u010dnih elektromehani\u010dkih releja, SSR obezbe\u0111uje:<\/p>

  • dugotrajan rad<\/strong> (bez potri\u0161noh kontakata),<\/p><\/li>

  • brz odaziv<\/strong>,<\/p><\/li>

  • be\u0161uman rad<\/strong>,<\/p><\/li>

  • preciznu kontrolu<\/strong> elektri\u010dnih potro\u0161a\u010da.<\/p><\/li><\/ul>

    Zbog toga su SSR releji idealni za industrijske primene<\/strong> poput greja\u010da u pe\u0107ima, pakericama, ma\u0161inama za pakovanje i svuda gde je potrebna precizna i tiha kontrola temperature<\/strong>.<\/p>

    Vrste SSR releja<\/h2>

    SSR releji se naj\u010de\u0161\u0107e dele na:<\/p>

    Po izlazu:<\/p>

    AC izlazni SSR \u2013 prekidaju ili propu\u0161taju naizmeni\u010dni (AC) napon, npr. 230 V ili 400 V.<\/p>

    DC izlazni SSR \u2013 koriste se za jednosmerne potro\u0161a\u010de poput DC motora, LED rasvete i elektronike.<\/p>

    Po ulaznom komandnom naponu:<\/p>

    DC upravljani SSR (3\u201332 VDC),<\/p>

    AC upravljani SSR (90\u2013280 VAC).<\/p>

    Po fazama:<\/p>

    Monofazni SSR,<\/p>

    Trofazni SSR.<\/p>

    Dodatna funkcija kod mnogih AC SSR releja je zero-cross okidanje \u2013 uklju\u010divanje kada mre\u017eni napon prolazi kroz nulu, \u0161to smanjuje smetnje i produ\u017eava vek trajanja opreme.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Kako izabrati pravi Solid State relej?<\/h2>

    Prilikom izbora SSR releja potrebno je obratiti pa\u017enju na slede\u0107e parametre:<\/p>

    1. Komandni napon (ulaz):<\/strong>
      Izmerite upravlja\u010dki napon ure\u0111aja (PLC, senzor, mikroprocesor). Ako je signal DC, koristite DC kontrolisani SSR<\/strong>; ako je AC, birajte AC kontrolisani SSR<\/strong>.<\/p><\/li>

    2. Izlazni napon i struja:<\/strong>
      Proverite maksimalnu struju potro\u0161a\u010da (izra\u017eenu u amperima). SSR relej treba da ima dozvoljeni opseg struje barem 2\u20133 puta ve\u0107i od potro\u0161a\u010da<\/strong> radi sigurnosti.<\/p><\/li>

    3. Vrsta napajanja potro\u0161a\u010da:<\/strong>
      Da li je u pitanju jednosmerni (DC)<\/strong> ili naizmeni\u010dni (AC)<\/strong> potro\u0161a\u010d.<\/p><\/li>

    4. Hla\u0111enje:<\/strong>
      Kod ve\u0107ih struja SSR se greje, pa je neophodno koristiti hladnjak (heatsink)<\/strong>.<\/p><\/li>

    5. Na\u010din kontrole:<\/strong>
      SSR se mo\u017ee kontrolisati:<\/p>

      • analognim signalom (0\u201310 V, 0\u201320 mA, 4\u201320 mA),<\/p><\/li>

      • naizmeni\u010dnim naponom (jedna ili vi\u0161e faza),<\/p><\/li>

      • jednosmernim naponom,<\/p><\/li>

      • pa \u010dak i potenciometrom<\/strong>.<\/p><\/li><\/ul><\/li><\/ol>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

        Kako se povezuje Solid State relej (SSR)?<\/h2>

        Povezivanje SSR releja je jednostavno i sli\u010dno kao kod klasi\u010dnog releja:<\/p>

        • Ulazna strana (kontrola):<\/strong>
          Obele\u017eena je kao + i \u2013<\/strong> ili A1 i A2<\/strong>. Tu se dovodi komandni napon (npr. 3\u201332 VDC). Kada se dovede napon, SSR se uklju\u010duje i propu\u0161ta struju ka potro\u0161a\u010du. Potro\u0161nja na ulazu je vrlo mala (par mA).<\/p><\/li>

        • Izlazna strana (snaga):<\/strong>
          Obele\u017eena kao 1 i 2<\/strong> ili T1 i T2 \/ L1 i L2<\/strong>. Na ovaj izlazni deo se povezuje potro\u0161a\u010d (greja\u010d, motor, rasveta). SSR tada prekida ili propu\u0161ta mre\u017eni napon ka potro\u0161a\u010du.<\/span><\/p><\/li><\/ul>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

          Solid state releji<\/strong> se koriste u razli\u010ditim industrijama i aplikacijama gde je potrebna precizna, tiha i pouzdana kontrola elektri\u010dnih potro\u0161a\u010da<\/strong>. Zahvaljuju\u0107i svom na\u010dinu rada bez mehani\u010dkih delova, idealni su za:<\/p>

          Industrijske pe\u0107i i greja\u010de<\/strong> \u2013 precizno odr\u017eavanje temperature bez varni\u010denja i tro\u0161enja kontakata.<\/p>

          Ma\u0161ine za pakovanje (pakerice, termo folije)<\/strong> \u2013 gde je potrebna brza i be\u0161umna reakcija releja.<\/p>

          Rasvetu i LED sisteme<\/strong> \u2013 naro\u010dito u automatizaciji i pametnim zgradama.<\/p>

          Motore i pumpe<\/strong> \u2013 kontrola start\/stop signala bez mehani\u010dkog habanja.<\/p>

          PLC i automatizovane sisteme<\/strong> \u2013 gde SSR komunicira direktno sa kontrolerima.<\/p>

          Elektronsku opremu i laboratorijske ure\u0111aje<\/strong> \u2013 gde je potrebna stabilna i \u010dista kontrola napajanja.<\/p>

          HVAC i klima sisteme<\/strong> \u2013 be\u0161umno uklju\u010divanje i isklju\u010divanje kompresora ili ventilatora.<\/p>

          Zbog svoje dugotrajnosti i pouzdanosti<\/strong>, SSR releji se sve \u010de\u0161\u0107e koriste kao zamena za elektromehani\u010dke releje u industriji, elektronici i automatizaciji.<\/p>
