Uyazi ukuthi mangaki ama-watts amandla ekhamera yokugada abaliwe?

Ukuze uphendule umbuzo abantu abaningi abawubuzile namuhla:
Mangaki amandla ekhamera ye-W DC 12V2A enamandla okugada, ukubala kanjani?
Mayelana nalo mbuzo, izimpendulo ezinikezwa ochwepheshe abahlukene azifani.Ngokuvamile, kunezimpendulo ezilandelayo:
①24W, amandla amakhamera agadayo anamandla amakhulu
②10W noma ngaphezulu.Uma kukhona amandla e-infrared LED, azokhuphuka kuye ngenani lama-LED
Eqinisweni, kulolu daba, singakubona ngale ndlela
12V*2A =24W Lokhu ukusetshenziswa kwamandla oku-2 kwekhamera egadayo, okungamandla
Uma i-12V10A switching power supply ingaletha amakhamera amaningi okuqapha we-12V2A
Amandla alinganiselwe okunikezwa kwamandla: 12X10=120W;amandla alinganiselwe ekhamera yokugada: 12X2=24W;ngokwesikhathi samanje: 10A ihlukaniswe ngo-2A=5;ngokwamandla: 120W ihlukaniswe ngo-24W=5;ngakho-ke i-5 ingafakwa (nge-voltage efanayo Kulesi simo, yikuphi okungaphansi kwamandla kanye namandla, sebenzisa lokho njengokujwayelekile).
Ngakho manje kulula kakhulu ukubuyela emuva futhi uqonde ubudlelwano phakathi kwamandla ekhamera nokunikezwa kwamandla.
