UPS yog ib lub tshuab fais fab uas tsis muaj kev cuam tshuam, uas muaj roj teeb cia, lub voj voog inverter thiab lub voj voog tswj. Thaum lub hwj chim tseem ceeb raug cuam tshuam, lub voj voog tswj ntawm UPS yuav ntes thiab pib lub voj voog inverter tam sim ntawd kom tso zis 110V lossis 220V AC, yog li cov khoom siv hluav taws xob txuas nrog UPS tuaj yeem ua haujlwm tau ib ntus, kom tsis txhob muaj kev poob los ntawm kev cuam tshuam hluav taws xob tseem ceeb.
Kev hloov pauv fais fab mov yog hloov 110V lossis 220V AC mus rau hauv DC uas xav tau. Nws tuaj yeem muaj ntau pawg ntawm DC tso zis, xws li ib-channel fais fab mov, ob-channel fais fab mov thiab lwm yam ntau-channel fais fab mov. Nws feem ntau muaj rectifier lim circuit thiab tswj circuit. Vim nws ua haujlwm tau zoo, me me thiab kev tiv thaiv zoo meej, nws yog dav siv hauv cov khoom siv hluav taws xob. Piv txwv li, khoos phis tawj, TV, ntau yam khoom siv, kev lag luam, thiab lwm yam.
1. Lub zog fais fab ntawm UPS muaj ib txheej roj teeb. Thaum tsis muaj hluav taws xob tsis ua haujlwm thaum lub sijhawm ib txwm muaj, lub charger sab hauv yuav them lub roj teeb, thiab nkag mus rau hauv lub xeev them nqi ntab tom qab them tag nrho kom tswj tau lub roj teeb.
2. Thaum lub hwj chim tas tsis tau xav txog, lub ups yuav hloov mus rau hauv lub xeev inverter hauv milliseconds kom hloov lub zog hauv lub roj teeb pob mus rau hauv 110V lossis 220V AC rau kev muab hluav taws xob tas mus li. Nws muaj qee qhov voltage stabilizing effect, Txawm hais tias qhov input voltage feem ntau yog 220V lossis 110V (Taiwan, Tebchaws Europe thiab Tebchaws Meskas), qee zaum nws yuav siab
siab thiab qis. Tom qab txuas nrog UPS, qhov hluav taws xob tso zis yuav tswj tau tus nqi ruaj khov.
UPS tseem tuaj yeem ua haujlwm tau ib ntus tom qab fais fab tuag. Nws feem ntau siv rau lub sijhawm tseem ceeb los buffer rau ib ntus thiab txuag cov ntaub ntawv. Tom qab fais fab tuag, UPS xa tawm lub suab ceeb toom kom ceeb toom txog kev cuam tshuam fais fab. Thaum lub sijhawm no, cov neeg siv tuaj yeem hnov lub suab ceeb toom, tab sis yuav luag tsis muaj lwm yam cuam tshuam, thiab cov khoom siv qub xws li khoos phis tawj tseem siv tau ib txwm.
