5A i 60A 24V DC i 12V DC Step Down Buck Converter

1. No ke aha i ʻoi aku ka kiʻekiʻe o kāu ʻōlelo ma mua o nā mea hoʻolako ʻē aʻe?

Ma ka mākeke Kina, nui nā hale hana e kūʻai aku i nā mea hoʻohuli haʻahaʻa i hōʻuluʻulu ʻia e nā hale hana liʻiliʻi ʻole. Hoʻopau kēia mau hale hana i nā kumukūʻai me ka hoʻohana ʻana i nā ʻāpana substandard. ʻO kēia ka hopena i nā pilikia palekana nui.

He hui ʻoihana ʻo SOLARWAY i ka R&D, ka hana ʻana, a me ke kūʻai ʻana i nā mea hoʻohuli mana. Ua komo ikaika mākou i ka mākeke Kelemania no nā makahiki he 10, e lawe aku ana ma kahi o 50,000 a 100,000 mau mea hoʻohuli mana i kēlā me kēia makahiki i Kelemānia a me kāna mau mākeke pili. Pono ka maikaʻi o kā mākou huahana i kāu hilinaʻi!

2. ʻEhia mau ʻāpana o kāu mau mea hoʻohuli mana e like me ka nalu puka?

ʻAno 1: Hoʻohana kā mākou NM a me NS moʻo i hoʻololi ʻia ʻo Sine Wave i ka PWM (Pulse Width Modulation) e hana i kahi hawewe sine i hoʻololi ʻia. Mahalo i ka hoʻohana ʻana i nā kaapuni naʻauao, hoʻolaʻa a me nā transistors pānaʻi kiʻekiʻe, hoʻemi nui kēia mau inverters i ka nalowale o ka mana a hoʻomaikaʻi i ka hana hoʻomaka palupalu, e hōʻoia ana i ka hilinaʻi nui. ʻOiai ʻo kēia ʻano o ka mana inverter hiki ke hoʻokō i nā pono o ka hapa nui o nā lako uila inā ʻaʻole koi nui ka mana o ka mana, ʻike mau ʻo ia ma kahi o 20% harmonic distortion i ka wā e holo ana i nā mea hana maʻalahi. Hiki nō hoʻi i ka mea hoʻohuli mana ke hoʻopilikia i nā mea kelepona lekiō. Eia nō naʻe, ʻoi aku ka maikaʻi o kēia ʻano o ka mana inverter, hana haʻahaʻa haʻahaʻa, haʻahaʻa ke kumu kūʻai, a no laila he huahana nui ma ka mākeke.

ʻAno 2: ʻO kā mākou NP, FS, a me NK series Pure Sine Wave inverters e hoʻohana i kahi hoʻolālā kaapuni hui kaʻawale, e hāʻawi ana i ka hana kiʻekiʻe a me nā ʻano nalu puka paʻa. Me ka ʻenehana kiʻekiʻe-frequency, ua paʻa kēia mau mea hoʻohuli mana a kūpono no ka nui o nā ukana. Hiki ke hoʻopili ʻia i nā mea uila maʻamau a me nā haʻahaʻa inductive （e like me nā pahu hau a me nā drills uila) me ka ʻole o ka hoʻopilikia ʻana (e laʻa, ka halulu a i ʻole ka leo TV). ʻO ka hoʻopuka ʻana o kahi mea hoʻohuli mana hawewe maʻemaʻe e like me ka mana grid a mākou e hoʻohana ai i kēlā me kēia lā - a ʻoi aku ka maikaʻi - ʻoiai ʻaʻole ia e hoʻopuka i ka pollution electromagnetic e pili ana i ka mana i hoʻopaʻa ʻia.

3. He aha nā mea hana hoʻouka resistive?

ʻO nā mea hana e like me ke kelepona paʻa lima, kamepiula, LCD TV, nā kukui uila, nā pā uila, nā mea hoʻolaha wikiō, nā mīkini paʻi liʻiliʻi, nā mīkini mahjong uila, a me nā mea kuke raiki i manaʻo ʻia he mau ukana pale. Hiki i kā mākou mea hoʻololi hawewe sine i hoʻololi ʻia ke hoʻoikaika i kēia mau mea hana.

4. He aha nā mea hana hoʻouka inductive?

ʻO nā hāmeʻa hoʻouka inductive nā mea e hilinaʻi nei i ka induction electromagnetic, e like me nā kaʻa, nā compressors, nā relay, nā kukui fluorescent, nā umu uila, nā pahu hau, nā ea, nā kukui mālama ikehu, a me nā pamu. Pono kēia mau mea hana i 3 a 7 mau manawa i ko lākou mana helu i ka wā hoʻomaka. ʻO ka hopena, ʻo kahi inverter hawewe maʻemaʻe wale nō i kūpono no ka mana iā lākou.

5. Pehea e koho ai i kahi inverter kūpono?

Inā loaʻa kāu ukana i nā mea hana pale, e like me nā ʻōpuʻu kukui, hiki iā ʻoe ke koho i kahi inverter hawewe sine i hoʻololi ʻia. Eia nō naʻe, no nā ukana inductive a me ka capacitive, manaʻo mākou e hoʻohana i kahi inverter hawewe sine maʻemaʻe. ʻO nā laʻana o ia mau ukana, ʻo ia ka pā, nā mea kani pololei, nā ea, nā pahu hau, nā mīkini kope, a me nā kamepiula. ʻOiai e hoʻomaka ana ka mea hoʻohuli i ka hawewe sine i hoʻololi ʻia i kekahi mau haʻahaʻa inductive, hiki iā ia ke hoʻopōkole i kona ola ʻana no ka mea e koi ana nā ukana inductive a me capacitive i ka mana kiʻekiʻe no ka hana maikaʻi loa.

6. Pehea wau e koho ai i ka nui o ka inverter?

Pono nā ʻano ukana like ʻole i ka nui o ka mana. No ka hoʻoholo ʻana i ka nui o ka inverter, pono ʻoe e nānā i nā helu mana o kāu mau ukana.

• Nā ukana pale: E koho i ka mea hoʻohuli me ka helu mana like me ka ukana.
• Haawe Capacitive: E koho i ka inverter me 2 a 5 manawa o ka mana o ka ukana.
• Nā ukana inductive: E koho i kahi mea hoʻohuli me 4 a 7 mau manawa o ka mana o ka ukana.

7. Pehea e hoʻopili ʻia ai ka pākaukau a me ka inverter?

Manaʻo ʻia ʻo nā uwea e hoʻopili ana i nā pauku pākaukau i ka inverter e like me ka hiki. No nā uwea maʻamau, ʻaʻole ʻoi aku ka lōʻihi ma mua o 0.5 mika, a ʻo ka polarity e kūlike ma waena o ka pākaukau a me ka inverter.

Inā pono ʻoe e hoʻonui i ka mamao ma waena o ka pākaukau a me ka inverter, e ʻoluʻolu e kelepona mai iā mākou no ke kōkua. Hiki iā mākou ke helu i ka nui a me ka lōʻihi o ke kaula kūpono.

E hoʻomanaʻo, hiki i nā pili uwea lōʻihi ke lilo i ka nalo uila, ʻo ia hoʻi, ʻoi aku ka haʻahaʻa o ka volter inverter ma mua o ka voltage terminal battery, e alakaʻi ana i kahi alarm undervoltage ma ka inverter.

8.Pehea ʻoe e helu ai i ka ukana a me nā hola hana e pono ai e hoʻonohonoho i ka nui o ka pākaukau?

Hoʻohana maʻamau mākou i kēia ʻano kumu no ka helu ʻana, ʻoiai ʻaʻole ia he 100% pololei ma muli o nā kumu e like me ke ʻano o ka pākaukau. Loaʻa paha i nā pila kahiko kekahi pohō, no laila pono e noʻonoʻo ʻia kēia he waiwai kuhikuhi:

Nā hola hana （H） = (Ka hiki ʻana i ka pākaukau （AH）*Veila uila （V0.8）)/ Mana hoʻouka （W）
