Xulashada Barkadda Iftiinka Dabaasha: AC12V vs DC12V & Tixgelinta Muhiimka ah
1. Maxay tahay sababta nalalka barkada dabaasha ay u isticmaalaan barkada dabaasha 12v transformer?
Barkadaha dabaasha waa deegaan qoyan oo gaar ah. Haddii ay si toos ah ugu shaqeyso 220V korontada dhexe, shil koronto oo halis ah ayaa dhici kara marka nalku soo daato. Barkadda dabaasha 12V Transformer waxa ay u rogi kartaa koronto sare{4}}koronto weyn oo Voltage ah 12V hoose{6}}koronto yar, si weyn u yaraynaysa halista shoogga korantada iyo u hogaansanaanta heerarka badbaadada barkadaha caalamiga ah (sida IEC 60364-7-702). Intaa waxaa dheer, 12V korantada hoose ee korantada ayaa aad ugu habboon deegaanka qoyan ee barkada marka loo eego shuruudaha daboolka ee khadadka nalalka, yaraynta khatarta badbaadada ee ay keento gabowga khadka, waana qaybta badbaadada aasaasiga ah ee nidaamka iftiinka barkada.
2. Waa maxay faraqa u dhexeeya AC12V iyo DC12V balliga dabaasha 12v transformers? Sidee loo doortaa?
Farqiga asaasiga ah ee u dhexeeya labada ayaa ku jira nooca wax soo saarka hadda iyo xaaladaha lagu dabaqi karo:
AC12V Transformer: Soo saara tamarta beddelka ah. Faa'iidooyinkeedu waa fogaanta gudbinta dheer (luminta danab yar gudahood 50 mitir) iyo qiimo jaban, taas oo ku haboon nalalka halogen dhaqameed iyo qaar ka mid ah nalalka barkada LED. Si kastaba ha ahaatee, waa in la ogaadaa in haddii nalka AC12V uu daboolay fiilooyinka, weli waxaa jira khatar yar oo shoog koronto ah, markaa waa in lagu isticmaalo sanduuqa isgoysyada biyuhu.
Transformer DC12V: Waxay soo saartaa haddalka tooska ah, kaas oo ka badbaado badan (ma jirto khatar galmo AC ah). Waa nooca caadiga ah ee nalalka barkada LED, oo leh xasillooni iftiin xoog leh iyo 5% -10% isticmaalka tamarta hoose marka loo eego nidaamyada AC12V. Laakin masaafada gudbinta ayaa ka gaaban ( dhexroorka siliga weyn ayaa loo baahan yahay in ka badan 30 mitir), qiimuhuna wax yar ayuu ka sarreeyaa.
Soo jeedinta xulashada: Qalabka DC12V ayaa doorbidaya nalalka barkada LED; Transformer-ka AC12V waxa loo dooran karaa laambadaha halogen-ka caadiga ah ama barkadaha waaweyn ee - (tuubada ka dheer 30 mitir), iyo ilaalinta dahaarka xadhkaha waa in la xoojiyaa isku mar.
3. Sidee loo go'aamiyaa awooda barkada dabaasha ee 12v transformer?
Mabda'a "wadarta awoodda + dib-u-celinta" waa in la raaco: marka hore xisaabi wadarta guud ee dhammaan nalalka barkadaha (tusaale, wadarta awoodda 5 20W LED nalalka waa 100W), ka bacdi 20%-30% korontadu dib u dhig si aad uga fogaato kulaylka iyo waxyeelada uu keeno transformerku oo ku socda culays buuxa. Habkani waa: koronto lagu qiimeeyay awood Ka weyn ama la mid ah wadarta guud ee awooda laambada × 1.2 (ama 1.3). Qaadashada wadarta awoodda laambada ee 100W tusaale ahaan, barkadda dabaasha 12v transformer ee 120W ama ka badan waa in la doortaa. Haddii laambadaha lagu daro mustaqbalka, xisaabinta waa in lagu saleeyaa wadarta awoodda balaarinta ka dib si looga fogaado beddelka joogtada ah ee transformers.
4. Waa maxay shahaadooyinka badbaadada iyo cabirrada ay tahay in fiiro gaar ah loo yeesho marka la dooranayo barkada dabaasha ee 12v transformer?
Shahaadada badbaadadu waa furaha: waa inay lahaataaIP67 ama ka sareeya qiimaynta biyuhu(IP68 muddo kooban ayaa lagu dhex milmi karaa biyaha, oo ku habboon bey'ada barkadda),Shahaadada CE(EU standard) amaShahaadada UL(Heerka Mareykanka), iyoShahaadada RoHS(shuruudaha ilaalinta deegaanka). Intaa waxa dheer, waa in fiiro gaar ah loo yeeshaa ilaalinta xad-dhaafka ah, ilaalinta wareegga gaaban, iyo hawlaha ilaalinta kulaylka - marka xariiqdu gaaban tahay{2}}waa in la wareego ama korontadu kor u kacdo, transformer-ku waxa uu si toos ah u jari karaa korontada si looga hortago in dab ama qalab waxyeelo gaadho. Marka la eego cabbirrada, danab-gelinta korantada waa in ay la mid noqoto korontada dhexe ee maxalliga ah (220V/50Hz ama 110V/60Hz), iyo cilladda xasilloonida korantada wax soo saarku waa in ay ka yar tahay ama la mid tahay ± 5% si loo hubiyo iftiinka caadiga ah ee laambadda.
5. Waa maxay taxaddarrada rakibaadda iyo dayactirka barkadda dabaasha ee 12v transformer?
Ka taxadarida rakibidda: ① Meesha rakibaadda waa in ay ka sarraysaa 50cm ee biyaha barkada, kana fog aagga buufinta iyo biyo-mareenka si looga fogaado in muddo dheer- biyo gelin; ② Isticmaal terminal biyuhu aanay biyuhu karin iyo cajalad dahaadh ah markaad fiilooyinka samaynayso si aad u hubiso xidhiidhka togan iyo taban ee saxda ah (DC12V waxay u baahan tahay inay kala saarto tiirarka togan iyo kuwa taban, AC12V uma baahna inay kala saarto laakiin waa in si adag loo xidho); ③ Xariiqda u dhaxaysa transformer-ka iyo laambaddu waa inay noqotaa tuubbo aan biyuhu lahayn oo PVC ah, qaybta la aasayna waa inay noqotaa mid liddi ku ah -daxalka.
Qodobbada dayactirka: ① Hubi in ay jiraan ururo biyo iyo wasakh dusha sare ee qalabka beddelka bil kasta, oo nadiifi wakhtiga; ② Tijaabi in korantada wax soo saarku ay deggan tahay iyo in kala-goysyada xariiqdu ay dabacsan yihiin rubuc kasta; ③ Iska ilaali in taransfooriyaha uu ku dhaco iftiinka qorraxda tooska ah ama heerkul aad u hooseeya muddo dheer si loo kordhiyo cimrigiisa adeeg.
