ʻO YUANKY NQ-40 Series DC Isolated Switch kahi mea hoʻokaʻawale uila hana kiʻekiʻe i hana kūikawā ʻia no nā ʻōnaehana mana photovoltaic (PV) a me nā ʻōnaehana mana DC ʻoihana, e hāʻawi ana i ka hoʻokaʻawale kaapuni hilinaʻi a me ka pale palekana no nā noi DC voltage kiʻekiʻe. Me ka volta insulation i helu ʻia o 1500V a me ka volta impulse i helu ʻia o 8000V, hāʻawi ia i ka hana insulation ikaika e kū i nā piʻi voltage a hōʻoia i ka palekana hana. Kākoʻo kēia moʻo i nā hoʻonohonoho 2-pole a me 4-pole, me kahi au wela i helu ʻia o 32A a me 1000A i helu ʻia ka mana hana pōkole, e hoʻokō ana i nā koi pale o nā ʻōnaehana DC mana waena.

Hoʻolālā ʻia no nā wahi waho ʻino, hōʻike ka kuapo NQ-40 i kahi helu palekana IP66 no nā ʻau a me nā lua kau ʻana, e pale pono ana i ke komo ʻana o ka lepo a me ka pīpī wai. Hana paʻa ia ma kahi pae mahana ākea loa mai -40 ℃ a i +85 ℃, e hoʻololi ana i nā kūlana aniau koʻikoʻi ma ka honua holoʻokoʻa. Kākoʻo ke kuapo i nā kaula paʻa, maʻalahi a me nā multicore me nā ʻāpana kea mai 2.5mm² a i 6mm², me nā torques paʻa i wehewehe pono ʻia no nā terminals a me nā wili kau ʻana e hōʻoia i ka hoʻonohonoho paʻa a maʻamau. ʻO kāna hoʻolālā pihi intuitive (OFF i ka hola 9, ON i ka hola 12) e hiki ai ke hana lima wikiwiki a palekana, ʻoiai ʻo ke ola mechanical o 10,000 mau pōʻaiapuni e hōʻoiaʻiʻo i ka lōʻihi o ka lōʻihi.

Hoʻohana nui ʻia ka moʻo NQ-40 i nā ʻōnaehana hana mana photovoltaic, e lawelawe ana ma ke ʻano he ʻāpana hoʻokaʻawale koʻikoʻi i nā kikowaena mana PV i hoʻopaʻa ʻia i ka grid a me waho o ka grid, nā inverters PV, nā keʻena hoʻolaha DC a me nā pahu combiner. ʻAe ia i ka hoʻokaʻawale palekana o nā PV arrays i ka wā mālama, hoʻoponopono pilikia a me nā pani ulia pōpilikia, e pale ana i nā limahana a me nā lako mai nā pōʻino uila. Eia kekahi, hoʻohana nui ʻia ia i nā ʻōnaehana mālama ikehu pākahiko, nā kikowaena kumu telecom, nā ʻōnaehana hoʻomalu DC ʻoihana a me nā ʻōnaehana pamu wai solar.

Me ka hoʻololi maikaʻi loa ʻana i ke kaiapuni, ka hana uila hilinaʻi a me ka hoʻonohonoho maʻalahi, hāʻawi ʻo YUANKY NQ-40 DC Isolated Switch i kahi hopena hoʻokaʻawale DC kūpono a palekana hoʻi no nā mea hoʻokomo PV honua, nā mea hoʻohui ʻōnaehana a me nā mea hana lako ikehu hou, e hōʻoiaʻiʻo ana i ka hana paʻa o nā ʻōnaehana mana DC ma nā ʻano paʻakikī like ʻole.
