Cov ntaub ntawv muaj zog tso saib ua haujlwm. LCD tuaj yeem tso saib DC input voltage, tso zis zaus, theem voltage, theem tam sim no, AC bypass input voltage, tso zis hwj chim KWH, lub sij hawm thiab hnub, kub, txhaum code zaub. .

Muab kev ua haujlwm qeeb qeeb, muab lub tswb nrov thiab tsis tshua muaj hluav taws xob thiab muab siab thiab qis voltage tig -tawm kev tiv thaiv muaj nuj nqi.

UPS muaj nuj nqi yog kom paub txog qhov hloov pauv tsis cuam tshuam ntawm ob lub zog siv hluav taws xob, muab lub sijhawm tshwj xeeb ntawm lub sijhawm thaub qab, hluav taws xob stabilization, zaus stabilization, cuam tshuam kev sib cais thiab lwm yam. Nws tuaj yeem thaiv qhov tsis sib xws tam sim ntawd, kev cuam tshuam kev sib raug zoo, kev hloov pauv hluav taws xob, kev hloov pauv ntau zaus, kev nce siab thiab lwm yam kev cuam tshuam hauv lub network ua ntej thauj khoom.
