Seb tus tsav tsheb LED muaj polarity nyob ntawm nws hom thiab kev khiav hauj lwm hom. Yog xav paub ntxiv txog cov khoom no, thov tso koj cov ntaub ntawv tiv tauj thiab peb yuav teb sai li sai tau.
Tsis tu ncua voltage LED tsav tsheb feem ntau tsis muaj polarity; cov zis yog DC voltage (piv txwv li, 12V / 24V), thiab tsuas yog yuav tsum muaj qhov sib txuam voltage. Cov tsav tsheb tam sim no lossis cov tsav tsheb uas muaj qhov dimming tuaj yeem muaj qhov polarity, thiab cov xaim yuav tsum tau ua raws li cov cim qhia kom tsis txhob muaj kev puas tsuaj. Cov kev faib tshwj xeeb yog raws li nram no:
Tsis tu ncua Voltage Drivers:
Tsau tso zis voltage (piv txwv li, 24V), polarity insensitive, feem ntau pom nyob rau hauv LED strips, advertising teeb lub thawv, thiab lwm yam.
Yog hais tias lub interface yog lub davhlau ya nyob twg thaiv, nws feem ntau yog cim "V + / V-" lossis "+/−", tab sis kev sib txuas rov qab feem ntau yuav tsis hlawv cov khoom siv (qee yam khoom tau tsim - hauv kev tiv thaiv kev tiv thaiv rov qab).
Constant Current Drivers:
Yuav tsum tau paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo polarity, feem ntau pom nyob rau hauv siab -power LED modules (xws li, cog cog teeb). Kev sib txuas rov qab tuaj yeem ua rau LED tsis teeb lossis ua rau muaj kev tiv thaiv hluav taws xob.
Lub davhlau ya nyob twg thaiv tau pom meej meej nrog polarity; Qee cov qauv siv xim coding (liab rau qhov zoo, dub rau qhov tsis zoo).
Smart/Dim Tsav Tsheb:
Qhov no yuav suav nrog cov kab teeb liab (xws li DALI, 0-10V). Kev xaim yuav tsum nruj me ntsis raws li phau ntawv qhia; rov qab kev sib txuas yuav ua rau kev tswj tsis tau.
