1. Haum rau kev tsim cov khoom siv me me, nrog rau ntau yam kev qhia tshwj xeeb ntawm qhov chaw xaiv koob;
2. Nrog ntau yam contour loj xaiv;
3. Ua tau raws li ROHS cov lus qhia;
Fais fab mov - Feem ntau yog DC qhov chaw uas nws tus kheej tswj los ntawm lwm qhov chaw AC xws li 120 v, 60 Hz kab.Yog li, hom hluav taws xob no tuaj yeem suav tias yog AC - DC hloov dua siab tshiab.
Ib qho AC qhov chaw uas muab qhov zaus tsis tu ncua, qhov ntsuas qhov tsis tu ncua, los ntawm DC qhov chaw hu ua inverter.Qee qhov hluav taws xob yog tswj los ntawm DC qhov chaw.Lub qhov dej tuaj yeem tsim lub zog ntawm ntau qib DC.Cov khoom siv hluav taws xob zoo li no hu ua DC-DC converters.
Rectifier: converts AC voltage rau pulsating DC voltage thiab tso cai rau tam sim no ntws nyob rau hauv ib qho kev taw qhia;
Low-pass lim: Nyob rau hauv rectified waveform muaj peev xwm suppress lub pulsation, thiab cia nws DC (txhais tau) tivthaiv los ntawm;
Voltage regulator: muaj peev xwm tswj tau tag nrho cov voltage tso zis nyob rau hauv cov kev mob ntawm kev hloov nyob rau hauv on-line voltage thiab load tam sim no los ntawm lub hwj chim mov.

dc lub qhov (socket) yog ib hom ntawm lub qhov (socket) nrog lub computer saib tshwj xeeb fais fab mov, nws yog tsim los ntawm transverse jack, longitudinal jack, rwb thaiv tsev puag, diav rawg hom hu shrapnel, directional keyway, ob rab diav rawg hom hu shrapnel nyob rau hauv nruab nrab ntawm lub hauv paus, mus rau hauv txoj kab ntsug thiab kab rov tav tsis txuas nrog.Ib qho kawg ntawm rab rawg hom kev sib cuag shrapnel yog ib qho chaw nres nkoj, nthuav tawm rau saum npoo ntawm lub hauv paus lub tog raj kheej, rau kev sib txuas ntawm cov khoom siv hluav taws xob los yog cov kab muag muag, lwm qhov kawg ntawm rab rawg hom kev sib cuag shrapnel yog tsim los ntawm ob txhais caj npab elastic interconnected los ntawm lub matrix, teem nyob rau hauv lub dc plug insertion kev taw qhia ntawm lub rwb thaiv tsev puag jack, muab lub computer saib, thiaj li hais tias nws yuav ua hauj lwm ib txwm.
