Cov khoom siv hluav taws xob hloov hluav taws xob (SMPS) ua haujlwm raws li cov pob txha tsim kho ntawm cov kev tshaj tawm sab nraum zoov niaj hnub, ua kom muaj kev ntseeg siab 24/7 ua haujlwm nyob rau hauv ib puag ncig huab cua. Lawv cov qauv tsim ncaj qha hais txog cov kev sib tw tshwj xeeb ntawm kev xa tawm sab nraum zoov. Cov khoom siv hluav taws xob hauv kev tshaj tawm sab nraum zoov hloov pauv tsis ruaj khov AC lub zog hluav taws xob (100-240V) rau hauv kev tswj hwm nruj, cov khoom siv hluav taws xob tsawg DC (xws li 5V, 12V, 24V) xav tau los ntawm LED cov lus qhia thiab cov tswj hwm. Qhov no suav nrog peb theem tseem ceeb:

1.Rectification: Diodes hloov AC rau pulsating DC.

2. Kev lim dej: Capacitors du voltage ripples, tshem tawm flicker hauv cov lus qhia.

3. Kev cai: Switching-mode circuits (SMPS) muaj qhov ruaj khov voltage (± 0.5% kam rau ua) txawm tias qhov hloov pauv hloov pauv lossis hloov pauv hloov pauv, kom ntseeg tau qhov ci ntsa iab thiab xim raug.

Lub luag haujlwm ua haujlwm hauv kev tshaj tawm sab nraud:

1.Harsh Ib puag ncig: Cov khoom siv hluav taws xob muaj qib ua haujlwm nyob rau hauv qhov kub thiab txias (-40 ° C txog + 85 ° C) nrog cov txheej txheem sib txawv kom tiv taus cov av noo, plua plav, thiab xeb-tseem ceeb rau cov ntawv tshaj tawm hauv huab cua hnyav.

2. Kev Tiv Thaiv Mechanisms: Integrated overvoltage (OVP), overcurrent (OCP), thiab luv-circuit (SCP) tiv thaiv tiv thaiv cov nqi siab LED modules los ntawm hluav taws xob puas.

3. Kev Siv Hluav Taws Xob: Cov thev naus laus zis zoo li cov kab hluav taws xob-cathode txo qis kev siv hluav taws xob los ntawm> 20%, txo cov nqi ua haujlwm rau cov khoom loj.

4.Stability Assurance: High refresh npaum li cas (> 3,840Hz) thiab qis ripple nrov (

Cov ntawv thov tseem ceeb:

1. LED Billboards: Powers high-resolution displays (piv txwv li, P3.91-P10 panels) rau cov chaw ntau pob los yog txoj kev loj, qhov voltage stability qhia pom qhov pom tseeb ntawm qhov sib txawv ntawm qhov pom.

2.Digital Signage Kiosks: Cov khoom siv 12V / 5V DC rau cov ntawv xov xwm tsheb thiab kev sib tham sib tshaj tawm hauv nroog cov chaw, vam khom kev ua haujlwm tsis zoo rau kev siv 24/7.

3.Smart Bus Shelters: Ua kom lub hnub ci-hybrid tshuab hloov thiab khaws lub zog rau kev txhawb nqa tus kheej illuminated tshaj tawm.

SMPS cov chav hloov pauv tsis ruaj tsis khov AC lub ntsiab rau hauv kev tswj hwm DC lub zog zoo thaum muaj sia nyob thermal cycling, noo noo, thiab hluav taws xob nrov.Lawv cov txheej txheem tiv thaiv ntau txheej thiab kev tsim kho muaj zog ua rau kev tshaj tawm sab nraum zoov siv tau nyob rau hauv qhov chaw xws li Arctic txoj kev loj mus rau qhov chaw sov ntawm ntug dej hiav txwv. Cov qauv Advanced tam sim no suav nrog IoT-enabled kev saib xyuas kev noj qab haus huv (kub / load diagnostics) rau preempt tsis ua hauj lwm - ib tug tseem ceeb evolution raws li digital signage scales mus rau 24/7 ua hauj lwm.
