Cov khoom siv fais fab hloov hom (SMPS) ua lub hauv paus tseem ceeb ntawm cov khoom siv tshaj tawm sab nraum zoov niaj hnub, ua kom muaj kev ua haujlwm 24/7 hauv qab qhov xwm txheej ib puag ncig hnyav. Lawv cov ntsiab cai tsim qauv ncaj qha daws cov teeb meem tshwj xeeb ntawm kev siv sab nraum zoov. Cov khoom siv fais fab hauv cov kab ke tshaj tawm sab nraum zoov hloov cov hluav taws xob AC tsis ruaj khov (100-240V) mus rau hauv cov zis DC uas tswj tau zoo, qis-voltage (piv txwv li, 5V, 12V, 24V) uas cov zaub LED thiab cov tswj hwm xav tau. Qhov no suav nrog peb theem tseem ceeb:

1. Kev kho kom zoo: Cov diodes hloov AC mus rau pulsating DC.

2. Kev lim dej: Cov capacitors du cov voltage ripples, tshem tawm flicker hauv cov zaub.

3. Kev Tswj Xyuas: Cov voj voog hloov pauv (SMPS) tswj tau qhov hluav taws xob ruaj khov (± 0.5% kev kam rau siab) txawm tias muaj kev hloov pauv ntawm qhov thauj khoom lossis kev hloov pauv ntawm cov tswv yim, ua kom muaj qhov ci ntsa iab thiab qhov tseeb ntawm xim.

Lub Luag Haujlwm Hauv Kev Tshaj Tawm Sab Nraud:

1. Ib puag ncig hnyav: Cov khoom siv fais fab qib kev lag luam ua haujlwm hauv qhov kub thiab txias heev (-40 ° C txog + 85 ° C) nrog cov txheej txheem conformal kom tiv taus cov av noo, hmoov av, thiab xeb - qhov tseem ceeb rau cov ntawv tshaj tawm hauv huab cua hnyav.

2. Cov Txheej Txheem Tiv Thaiv: Kev tiv thaiv overvoltage (OVP), overcurrent (OCP), thiab short-circuit (SCP) tiv thaiv cov modules LED muaj nqis siab los ntawm kev puas tsuaj hluav taws xob.

3. Kev Siv Hluav Taws Xob Zoo: Cov thev naus laus zis zoo li cov kab ke cathode sib xws txo cov kev siv hluav taws xob ntau dua 20%, txo cov nqi ua haujlwm rau cov zaub loj.

4. Kev Ruaj Ntseg Ruaj Ntseg: Cov nqi refresh siab (>3,840Hz) thiab suab nrov qis (

Cov Ntawv Thov Tseem Ceeb:

1. Cov Ntawv Tshaj Tawm LED: Muab lub zog rau cov zaub daws teeb meem siab (piv txwv li, P3.91–P10 panels) rau cov chaw ntau pob lossis txoj kev loj, qhov twg qhov hluav taws xob ruaj khov txhais tau tias pom tseeb ntawm ntau qhov kev pom deb sib txawv.

2. Cov Kiosks Kos Npe Digital: Muab 12V/5V DC rau cov ntawv qhia txog kev khiav tsheb thiab cov ntawv tshaj tawm sib tham hauv nroog, vam khom kev ua haujlwm tsis ua haujlwm rau kev siv 24/7.

3. Chaw Nres Tsheb Npav Ntse: Ua rau cov tshuab hluav taws xob hnub ci hloov pauv thiab khaws cia lub zog rau cov tshaj tawm uas ci ntsa iab.

Cov chav SMPS hloov cov hluav taws xob AC tsis ruaj khov mus rau hauv lub zog DC uas tswj tau zoo thaum tseem muaj sia nyob rau lub sijhawm kub, dej noo, thiab suab nrov hluav taws xob. Lawv cov qauv tiv thaiv ntau txheej thiab kev tsim kho kom ruaj khov ua rau cov khoom tshaj tawm sab nraum zoov siv tau rau hauv qhov chaw xws li Arctic txoj kev loj mus rau thaj chaw ntug dej hiav txwv sov. Cov qauv siab heev tam sim no suav nrog IoT-enabled kev saib xyuas kev noj qab haus huv (kub / load diagnostics) los tiv thaiv kev ua tsis tiav - qhov kev hloov pauv tseem ceeb thaum cov paib digital nce mus rau 24/7 kev ua haujlwm.
