Momwe mungasankhire magetsi opangira magetsi a LED?

1. Njira zogulira magetsi opangira magetsi

Zosankha zopangira magetsi opangira magetsi makamaka zimaphatikizira kutalika kwa mzere wowunikira, mphamvu ndi mphamvu ya mzere wowunikira. Zosankha zenizeni ndi izi:

1. Kutalika kwa mzere wowala: Kusankha magetsi oyenera malinga ndi kutalika kwa mzere wowunikira kumatha kukulitsa moyo wautumiki ndi kukhazikika.

2. Mphamvu ya mzere wopepuka: Sankhani mphamvu yofananirayo molingana ndi mphamvu ya chingwe chowunikira. Kuchuluka kwa mphamvu, kumafunikanso mphamvu zambiri.

3. Panopa: Sankhani mphamvu yofananira malinga ndi momwe mzere wowala umayendera. Kuchuluka kwa magetsi, kumafunikanso mphamvu zambiri.

2. Mafotokozedwe a magetsi opangira magetsi

1. 12V magetsi: oyenera mabala amtundu umodzi komanso otsika kwambiri a RGB, makamaka pamizere yayifupi yowala.

2. Magetsi a 24V: oyenerera mizere yowunikira yamphamvu ya RGB ndi mizere yayitali yayitali.

3. 48V magetsi: oyenerera mizere yoyera yamphamvu yamphamvu, komanso yoyenera mizere yowunikira yomwe imasakaniza kuwala koyera ndi kuwala kwa RGB.

3. Momwe mungawerengere bwino mphamvu yamagetsi opangira magetsi

Njira yowerengera kuchuluka kwa mphamvu ya chingwe chowunikira ndi: kutalika kwa chingwe chowunikira (mita) × mphamvu (W/M) ÷ mphamvu yamagetsi (%) × kokwanira (1.2). Coefficient ndi 1.2 kuonetsetsa chitetezo ndi kudalirika.

Mwachitsanzo: Munagula chingwe chopepuka cha 12V 5050 chokhala ndi utali wa mita 5, mphamvu ya 14.4W/M, ndi mphamvu ya 90%. Malinga ndi formula, titha kupeza:

5 (mita) × 14.4 (W/M) ÷ 90% × 1.2 = 96W

Chifukwa chake, muyenera kusankha mphamvu ya 12V yokhala ndi mphamvu ya 96W.

4. Momwe mungayikitsire magetsi opangira magetsi

1. Mphamvu yamagetsi yamagetsi iyenera kuyikidwa m'njira yosalowa madzi ndikuyesera kupewa kunyowa.

2. Musanakhazikitse, muyenera kuyang'ana ngati mphamvu yamagetsi yamagetsi ndi mphamvu yamagetsi yamagetsi amagetsi.

3. Tsukani mabowo ochotsa kutentha kwa magetsi nthawi zonse kuti muwonetsetse kuti kutentha kumatulutsa kutentha.

Mwachidule, ndikofunikira kusankha magetsi oyenera, omwe sangangowonjezera moyo wautumiki wa chingwe chowunikira, komanso kuwonetsetsa kuwala ndi zotsatira za chingwe chowunikira. Ngati simukudziwa momwe mungasankhire magetsi oyenera, mutha kufunsa akatswiri odziwa ntchito.
