Cov khoom siv fais fab hloov hom (SMPS) yog cov khoom siv hloov pauv hluav taws xob tseem ceeb uas ua rau cov duab ci ntsa iab thiab muaj zog ntawm cov ntxaij vab tshaus LED niaj hnub no hla ntau yam kev siv. Lawv qhov ua tau zoo, me me, thiab kev xa hluav taws xob meej yog qhov tseem ceeb rau kev ua tau zoo thiab kev ntseeg tau.

Cov Ntawv Thov Tseem Ceeb:

Cov Zaub Loj: Cov chaw ua si Jumbotrons, cov ntawv tshaj tawm sab nraum zoov, thiab cov phab ntsa video hais kwv txhiaj vam khom rau SMPS muaj zog heev. Cov ntxaij vab tshaus loj no xav tau lub zog loj heev thiab ruaj khov faib thoob plaws ntau txhiab lub modules.

Cov Paib Qhia Sab Hauv Tsev & Chav Tswj: Cov chaw tos txais qhua hauv tuam txhab, kev tshaj tawm muag khoom, cov chaw tshaj tawm hauv xov tooj cua, thiab cov phab ntsa video hauv chav tswj hwm lub luag haujlwm tseem ceeb siv SMPS, lub zog txhim khu kev qha tseem ceeb rau kev ua haujlwm ntev thiab kev tso saib cov ntaub ntawv tseem ceeb.

Kev Xauj Tsev & Kev Npaj Khoom Rau Kev Tshwm Sim: Cov vaj huam sib luag LED portable rau kev hais kwv txhiaj, kev nthuav qhia, thiab cov rooj sib tham siv SMPS uas muaj nqis rau lawv lub zog ceev ceev (ua rau lub teeb yuag, tsim qauv modular) thiab muaj peev xwm los tswj cov hluav taws xob nkag tau sib txawv uas ntsib thoob ntiaj teb.

Suab zoo & Saib ncaj qha LED (DVLED): Cov zaub sab hauv tsev uas muaj kev daws teeb meem siab thiab cov TV LED uas pom ncaj qha ntau zuj zus nyob ntawm SMPS kom ruaj khov.

Cov Chaw Thauj Mus Los: Cov ntaub ntawv tso tawm hauv tshav dav hlau, chaw nres tsheb ciav hlau, thiab hauv av xav tau SMPS muaj zog uas muaj peev xwm ua haujlwm tau zoo hauv cov chaw nyuaj uas muaj kev hloov pauv hluav taws xob.

Cov Khoom Siv Fais Fab Thawj Zaug & Cov Voltages:

Qhov Hluav Taws Xob Tsis Tu Ncua (CV) SMPS: Hom uas siv ntau tshaj plaws. Muab lub zog hluav taws xob DC uas raug tswj kom nruj rau lub zog ntawm cov LED modules thiab cov circuitry cuam tshuam.

Cov Hluav Taws Xob Tawm Tawm Feem Ntau: 5V DC (rau cov logic sab hauv, cov tsav tsheb, qee cov modules zoo-suab), 12V DC (feem ntau rau ntau lub modules sab hauv tsev), 24V DC (feem ntau rau cov modules sab nraum zoov, cov cable ntev dua), 48V DC (Nrov zuj zus rau cov zaub muaj zog siab thiab cov ntawv thov PoE vim tias tam sim no qis dua / poob).

Cov Tsav Tsheb Tam Sim No (CC): Txawm hais tias cov khoom siv hloov hluav taws xob tshwj xeeb (feem ntau kuj yog hom hloov pauv), cov no tau koom ua ke hauv cov modules LED lossis txee. Lawv tau txais DC voltage (feem ntau yog 5V, 12V, 24V, lossis 48V los ntawm CV SMPS tseem ceeb) thiab xa cov hluav taws xob tas mus li ncaj qha mus rau cov hlua LED pixel, kom ntseeg tau tias muaj qhov ci thiab xim sib xws. Cov zaub muaj zog siab yuav siv cov tsav tsheb CC tshwj xeeb uas tau teeb tsa ze rau LEDs.

Fais fab hla Ethernet (PoE) / PoE ++ Hloov: Rau cov paib qhia me me lossis cov chaw tswj hwm hauv cov zaub loj, SMPS sib xyaw ua ke rau hauv PoE switches muab ob qho tib si cov ntaub ntawv thiab lub zog (feem ntau 48V DC) hla ib txoj hlua.

Cov Qib Fais Fab:

Cov kev xav tau fais fab sib txawv heev:

Cov Cim Me Me Hauv Tsev: Kaum tawm mus rau ntau pua Watts.

Phab Ntsa Sab Hauv Tsev Uas Muaj Kev daws teeb meem siab: Pua pua Watts mus rau ntau Kilowatts (kW) ib square meter qhov ci ntsa iab.

Cov Ntawv Tshaj Tawm Sab Nraud / Cov ntxaij vab tshaus Chaw Ua Si: Tag nrho lub zog ntawm lub cev muaj zog yog kaum txog pua kW. SMPS uas muaj zog ntau (>100W ib cubic inch) yog qhov tseem ceeb.

Xaus lus:

SMPS, feem ntau yog cov khoom siv hluav taws xob tas mus li uas ua haujlwm tau zoo (> 90%) uas xa hluav taws xob 5V, 12V, 24V, lossis nce mus txog 48V DC, tsim lub zog tseem ceeb ntawm txhua lub vijtsam LED. Ua haujlwm nrog cov tsav tsheb tam sim no tas mus li, lawv ua rau muaj peev xwm nthuav dav, ci ntsa iab, ntseeg tau, thiab pom kev zoo nkauj uas xav tau thoob plaws cov ntawv thov los ntawm cov vaj huam sib luag me me mus rau cov tsom iav uas puv chaw ua si.
