ʻO ka hana hou o ka mokuʻāina paʻa: Hoʻomohala ʻana i nā mea haʻihaʻi DC e pili ana i ka semiconductor no ka hana <1ms i nā noi pale pākaukau koʻikoʻi

No nā kikoʻī kikoʻī, ka hoʻonohonoho ʻana o ka pale PV solar, ka hoʻolālā ʻana o ka ʻōnaehana mālama pākaukau, a i ʻole ka hoʻonohonoho ʻana i ka loiloi hale hana, hāʻawi kā mākou hui ʻenekinia i ke kūkākūkā pololei e hōʻoia i kāu ʻōnaehana mana DC e hoʻokō i nā koi palekana a me nā pahuhopu hilinaʻi hana.

1000V DC i hoʻoheheʻe ʻia i ka hihia kaapuni

He mea hana pono ʻo CDADA ma Kina, hiki ke hāʻawi iā 1000V DC Molded Case Circuit Breaker ma ka honua holoʻokoʻa. Aia ia i ka 800A, IEC-compliant, no ka lā PV & DC grids. Nā koho 2P/4P, 20–40kA haʻihaʻi, me kahi kaʻawale a me nā mea pono. DIN a i ʻole ka mauna panel. Ua hilinaʻi ʻia e nā mea hoʻohui solar honua.

250V DC kaapuni kaapuni liʻiliʻi

He koho maikaʻi ʻo CDADA e lilo ʻoe i mea hoʻolako iā DAB7-63 250V DC Miniature Circuit Breaker 1P, 1–63A, me 6kA kaha haki. He kūpono kēia huahana no ka PV solar, telecom & DC system. Kau ʻia ʻo DIN-rail, me ka hōʻailona ON/OFF akaka a me ka hoʻokō RoHS. E ʻoluʻolu e kelepona mai iā mākou e kiʻi i kahi kumu kūʻai pololei.

Nānā hou aku >> E hoʻouna i ka nīnau >>

He Kaapuni Kaapuni DC mea hana a mea hoʻolako ʻo CDADA ma Kina. Hāʻawi kā mākou hale hana i nā ʻoihana like ʻole e like me nā ʻōnaehana mana, kūkulu ʻana i ka automation, a me ka hana ʻenehana, e hāʻawi ana i nā hoʻonā OEM/ODM maʻalahi.
