Cov FAQ
Dab tsi yog qhov tseem ceeb tshaj plaws thaum xaiv kev lag luam kev lag luam?
Koj yuav tsum nco ntsoov xyuas cov hom load thiab nws cov kev ntaus nqi ua ntej. Qhov no pab koj xaiv ib tus relay uas ua haujlwm kom nyab xeeb thiab kav ntev dua. Sib piv rau relay rau koj lub thauj khoom ua rau koj lub cev khiav zoo.
Kuv puas tuaj yeem siv cov relay rau ob qho tib si AC thiab DC thauj khoom?
Tsis yog, koj tsis tuaj yeem siv cov relay rau ob qho tib si. Koj yuav tsum tau kuaj xyuas yog tias cov relay yog nyob rau AC, DC, lossis ob qho tib si. Siv lub hom tsis yog yuav ua rau cov relay poob rau lossis txawm ua puas koj cov khoom siv.
Kuv yuav paub tau li cas yog tias kuv relay xav tau kev tiv thaiv ntxiv?
Yog tias koj lub nra muaj cov siab dua qub lossis tsim cov txim taws, koj yuav tsum tau ntxiv kev tiv thaiv. Siv Fuses, Snubber Circuits, lossis Surge tiv thaiv. Cov cuab yeej siv no pab koj cov xa tawm ntev dua thiab ua kom koj lub cev muaj kev nyab xeeb.
Kuv yuav tsum tau kuaj xyuas ntau npaum li cas lossis hloov kuv cov khoom lag luam muaj kev lag luam?
Koj yuav tsum kuaj xyuas rov qab thaum lub sijhawm saib xyuas tas li. Saib rau cov cim ntawm hnav, av, lossis overheating. Hloov kev sib txuas yog tias koj pom teeb meem lossis tom qab ncav cuag lub neej pom zoo ntawm cov khw.
