YUANKY NQ-40 Series DC Isolated Switch yog ib lub cuab yeej hluav taws xob ua haujlwm siab uas tsim tshwj xeeb rau photovoltaic (PV) thiab cov tshuab hluav taws xob DC hauv kev lag luam, xa cov kev txiav tawm ntawm lub voj voog txhim khu kev qha thiab kev tiv thaiv kev nyab xeeb rau cov ntawv thov DC hluav taws xob siab. Nrog rau qhov ntsuas hluav taws xob rwb thaiv tsev ntawm 1500V thiab qhov ntsuas hluav taws xob impulse withstand voltage ntawm 8000V, nws muab kev ua haujlwm rwb thaiv tsev zoo kom tiv taus qhov hluav taws xob nce siab thiab xyuas kom muaj kev nyab xeeb ua haujlwm. Cov koob no txhawb nqa 2-pole thiab 4-pole configurations, nrog rau qhov ntsuas hluav taws xob thermal ntawm 32A thiab 1000A rated luv-circuit ua peev xwm, ua tau raws li cov kev cai tiv thaiv ntawm cov tshuab DC nruab nrab-zog.

Tsim los rau qhov chaw nyob sab nraum zoov uas nyuaj heev, lub qhov hloov NQ-40 muaj qib kev tiv thaiv IP66 rau cov qhov thiab cov qhov txuas, tiv thaiv tau zoo rau cov hmoov av thiab dej txau. Nws ua haujlwm ruaj khov thoob plaws qhov kub thiab txias dav heev txij li -40 ℃ txog +85 ℃, hloov kho rau cov huab cua hnyav thoob ntiaj teb. Lub qhov hloov txhawb nqa cov xov hlau khov kho, yoog tau thiab ntau lub plawv nrog cov ntu hla ntawm 2.5mm² txog 6mm², nrog rau cov torques nruj meej rau cov terminals thiab cov ntsia hlau txuas kom ntseeg tau tias muaj kev teeb tsa ruaj ntseg thiab tus qauv. Nws tsim lub pob qhov rooj yooj yim (OFF thaum 9 teev, ON thaum 12 teev) ua rau kev ua haujlwm tes ceev thiab muaj kev nyab xeeb, thaum lub neej kho tshuab ntawm 10,000 lub voj voog lav qhov ruaj khov mus sij hawm ntev.

Cov koob NQ-40 feem ntau yog siv rau hauv cov tshuab tsim hluav taws xob photovoltaic, ua haujlwm ua ib qho khoom tseem ceeb hauv cov chaw tsim hluav taws xob PV uas txuas nrog grid thiab off-grid, PV inverters, DC distribution cabinets thiab combiner boxes. Nws tso cai rau kev txiav tawm ntawm PV arrays thaum lub sijhawm txij nkawm, kev daws teeb meem thiab kev kaw thaum muaj xwm txheej ceev, tiv thaiv cov neeg ua haujlwm thiab cov khoom siv los ntawm kev phom sij hluav taws xob. Tsis tas li ntawd, nws tau siv dav hauv cov tshuab khaws cia roj teeb, chaw nres tsheb hauv xov tooj, cov tshuab tswj DC hauv kev lag luam thiab cov tshuab nqus dej hnub ci.

Nrog kev hloov pauv ib puag ncig zoo heev, kev ua haujlwm hluav taws xob txhim khu kev qha thiab kev teeb tsa yooj yim, YUANKY NQ-40 DC Isolated Switch muab kev daws teeb meem DC cais tawm uas pheej yig thiab muaj kev nyab xeeb rau cov neeg teeb tsa PV thoob ntiaj teb, cov neeg sib koom ua ke thiab cov chaw tsim khoom siv hluav taws xob tshiab, ua kom muaj kev ua haujlwm ruaj khov ntawm DC fais fab systems hauv ntau qhov xwm txheej nyuaj.
