Monga katswiri wopanga magetsi otsika mphamvu komanso zaka 20 akugwira ntchito m'makampani, YUANKY ikupereka DC S7 SeriesChotsukira Dera Chaching'ono cha Dzuwa cha DC(MCB), yankho lapamwamba kwambiri lopangidwira chitetezo cha DC circuit ndi kudzipatula, lokonzedwa bwino kuti ligwiritsidwe ntchito pakupanga ma solar a photovoltaic (PV). Likupezeka mu 1P mpaka 4P configurations, limathandizira ma voltages ovotedwa kuyambira DC250V mpaka 1000V, current yovotedwa kuyambira 6A mpaka 50A, ndi C-type tripping characteristics (7In-15In). Limapereka 6kA rated breakability ndi 15kA limited short-circuit breakability pa 250VDC, ndi ultra-fast response time ≤4ms. Kapangidwe kake katsopano kopanda polarized ndi chinthu chofunikira kwambiri, chochotsa polarity differential panthawi ya mawaya, kusunga kwambiri nthawi yoyika ndikupewa zolakwika za mawaya.

DC MCB iyi imagwira ntchito pa njira yotetezera kawiri kuti ithetse mavuto omwe amafala kwambiri pa dongosolo la DC. Pofuna kuteteza kwambiri, mzere wa bimetallic womwe uli mkati mwake umapindapinda ndi kutentha kuti uyambe kugwetsa, ndikudula dera bwino pamene zinthu zikuchulukirachulukira kuti zisamawonongeke nthawi zonse. Pamavuto afupikitsa, kutulutsa kwamagetsi kwamphamvu kwambiri kumayamba kugwira ntchito nthawi yomweyo, kusokoneza mphamvu yamagetsi mkati mwa ≤4ms kuti tipewe zoopsa kuchokera ku ma arc a DC. Pokhala ndi makina ozimitsira arc a DC, imathetsa vuto la kutha kwa arc m'mabwalo a DC popanda malo achilengedwe odutsira zero, kuonetsetsa kuti kusweka kuli kotetezeka komanso kodalirika. Kapangidwe ka DIN rail mounting kamalola kuyika kosavuta komanso mwachangu m'makabati ogawa wamba.

Potsatira kwambiri miyezo yapadziko lonse ya IEC 60947-1/2, chinthuchi chili ndi satifiketi ya CE ndi malipoti oyesera a CB operekedwa ndi SEMKO, omwe akukwaniritsa zofunikira pakupeza msika wapadziko lonse. Chimagwira ntchito bwino mu -5℃ mpaka +60℃, chimasintha malinga ndi mikhalidwe yosiyanasiyana yovuta yogwirira ntchito. Chimagwiritsidwa ntchito kwambiri mumakina a PV olumikizidwa ndi gridi/opanda gridi, makina osungira mphamvu za batri, mapanelo ogawa a DC, malo olumikizirana, zida zatsopano zamagetsi ndi ma DC control circuits amafakitale, ndi chisankho chabwino kwambiri kwa okhazikitsa ma PV, ophatikiza makina ndi makontrakitala amagetsi padziko lonse lapansi. Mothandizidwa ndi kuwongolera kwapamwamba kwambiri komanso ntchito yonse yogulitsa musanagulitse & mutagulitsa, YUANKY DC MCB imapereka chitetezo chodalirika komanso chokhalitsa kwamakina amagetsi a DC padziko lonse lapansi.
