Ua haujlwm rau teeb pom kev zoo thaum muaj xwm ceev LED

2020/12/05

Cov teeb taws xwm ceev LED yuav tsum muaj nrog cov khoom siv thaum muaj xwm ceev-inverter (inverter). Inverter yog DC (lub roj teeb, roj teeb cia) rau hauv kev hloov tam sim no (feem ntau 220v50HZ sine lossis square yoj). Kev siv hluav taws xob thaum muaj xwm ceev, feem ntau thim rov qab rau hauv 220V AC DC roj teeb. Feem ntau hais lus, inverter yog DC tam sim no (DC) rau hauv kev hloov pauv tam sim no (AC) ntawm lub ntaus ntawv. Nws los ntawm inverter, tswj kev logic thiab lim Circuit Court.


Thaum cov hluav taws xob AC txuas, inverter thaum muaj xwm ceev teeb lub roj teeb them, rov qab cov xwm txheej thaum lub zog hluav taws xob lossis av qeeg, tawm tsam, tawg thiab lwm yam xwm txheej lossis lwm yam xwm txheej tshwm sim los ntawm cov hluav taws xob AC tau cuam tshuam, inverter pib, hloov lub roj teeb txuas ntxiv lub teeb teeb, lub sijhawm hloov pauv qis dua 0.1 vib nas this. Txheeb xyuas lub roj teeb sib txawv sib txawv li 1-3 teev lub sijhawm muaj teeb pom kev zoo thaum muaj xwm ceev, siv tau rau ntau qhov kev xav tau. -25- + 70 kub ib puag ncig.
