Ndi iti yabwino - 12V kapena 24V?

Chisankho chofala posankhaMzere wa LED ndi 12V kapena 24VZonse ziwiri zimakhala ndi magetsi otsika mphamvu, ndipo 12V ndiye kugawa kofala kwambiri. Koma ndi chiyani chabwino?

Zimadalira zinthu zosiyanasiyana, koma mafunso omwe ali pansipa ayenera kukuthandizani kuchepetsa vutoli.

(1) Malo anu.

Mphamvu ya magetsi a LED ndi yosiyana. Chingwe cha magetsi cha 12V chili ndi mphamvu yochepa ndipo chimagwiritsidwa ntchito nthawi zina. Chingwe cha magetsi cha 24V chili ndi mphamvu yayikulu ndipo chimagwiritsidwa ntchito m'malo osiyanasiyana.

(2) Kodi muli ndi tsatanetsatane wa magetsi omwe alipo kale?

Mwachitsanzo, ngati mukugwiritsa ntchito mabatire a 12V kapena muli kale ndi zida zamagetsi za 12V, zingakhale bwino kuonetsetsa kuti zingwe zatsopano za LED zikugwirizana ndi zomwe muli nazo kale.

Mwanjira imeneyi, simudzafunika kugula magetsi atsopano kuti mugwirizane ndi ma LED.

(3) Malo ozizira komanso kutalika kofunikira.

Chingwe cha magetsi cha 12V chili ndi mphamvu zochepa komanso zofunikira zochepa pakuchotsa kutentha. Chifukwa cha mphamvu zake zambiri, zingwe za magetsi za 24V zimakhala ndi zofunikira zambiri pakuchotsa kutentha. Mu ntchito monga kuwunikira kwa LED, kutalika kopitilira kwa chingwe cha LED nthawi zambiri kumayendetsedwa ndi mphamvu yamagetsi yomwe ma LED strip copper traces amatha kugwira. Chifukwa chake, zingwe za LED za 24V nthawi zambiri zimatha kugwira kawiri kutalika komwe chingwe cha LED cha 12V chingachite, poganiza kuti mphamvu ya zinthu ziwirizi ndi yofanana. Chingwe cha 12V chokhala ndi mphamvu yamagetsi yotsika ndi mwendo wocheperako kuposa 24V.

(4) Mphamvu yogwira ntchito ya mikanda ya nyali ndi yosiyana.

Pofuna kupititsa patsogolo kusinthasintha komanso kusinthasintha, nthawi zambiri imapangidwa kuti iziyendetsedwa ndi magetsi a 12V DC. Voltage yogwira ntchito ya mikanda itatu ya nyali motsatizana ndi pafupifupi 9.6V.

Mwachidule, makina a LED a 24V adzakoka theka la mphamvu yamagetsi ngati makina a LED a 12V kuti akwaniritse mphamvu yomweyo.

Koma zonse pamodzi, kaya ndi mtundu wanji wa choyezera kuwala, ndibwino kuti chigwirizane ndi zosowa zanu. Timaperekamipiringidzo ya magetsi otsika ndi okwera mphamvu, komanso zingakhale zofunikira pa makonda anu, chonde musazengereze kulumikizana nafe
