Txoj kev tsav tsheb feem ntau muab faib ua ob pawg: qhov tam sim no tsis tu ncua (CC) thiab qhov tsis tu ncua voltage (CV). Ib qho kev tsav tam sim no tsis tu ncua tso tawm qhov tam sim no tsis tu ncua, thaum qhov tso zis DC voltage sib txawv nyob rau hauv ib qho chaw nyob ntawm qhov load kuj. Cov kab hluav taws xob tsis tu ncua tsis ntshai ntawm luv luv Circuit Court, tab sis qhov qhib tag nrho yog txwv nruj heev. Cov tsav tam sim no tsis tu ncua yog qhov zoo tagnrho rau kev tsav tsheb LEDs, tab sis lawv kuj kim heev. Piv rau tag nrho cov tam sim no tas mus li, ib tus neeg tsis tu ncua tsav tam sim no muaj qhov tsis zoo thiab kim dua, tab sis lawv tiv thaiv LEDs tiag tiag thiab txuas ntxiv lawv lub neej, ua rau tib neeg tsis tu ncua tam sim no rau yav tom ntej.
Core electrical parameters include output type, output current and accuracy, output voltage range, output power, input voltage range, efficiency and power factor, and operating temperature range. Output types are either constant voltage (CV) or constant current (CC), with current accuracy of ±3% to ±5%. The output power calculation formula is: Output Voltage (V) × Output Current (A) = Power (W). The commonly used input voltage range is AC 100-240V wide voltage, power factor (PF) value >0.9, conversion efficiency >85%. Kev khiav hauj lwm kub yog feem ntau yog -30℃~ +70℃. Cov ntawv thov tshiab kuj xav tau cov tsav tsheb uas siv bandgap qis thiab PWM brightness hloov ua haujlwm. Raws li cov qauv hauv Circuit Court, lub ntsiab hom muaj xws li resistor thiab capacitor kauj ruam -down, pa transformer kauj ruam -down, hluav taws xob transformer kauj ruam -down, RCC kauj ruam-down switching fais fab mov, PWM tswj switching fais fab mov, thiab lwm yam. PWM tswj switching fais fab mov muaj tsis tshua muaj hluav taws xob efficiency, feem ntau 80% tawm voltage thiab ruaj khov tam sim no. Feem ntau, hom Circuit Court no muaj kev tiv thaiv tag nrho thiab yog lub zog muaj kev ntseeg siab. Cov kev tiv thaiv tseem ceeb uas LED tsis tu ncua tam sim no tsav lub zog yuav tsum muaj xws li kev tiv thaiv luv luv Circuit Court (SCP), kev tiv thaiv overload (OLP), thiab kev tiv thaiv overvoltage (OVP). Lwm yam kev tiv thaiv muaj xws li kev tiv thaiv rov qab, kev tiv thaiv kev tiv thaiv, thiab lwm yam. Cov khoom pov thawj uas muaj xws li CCC, CE, UL, TUV, thiab lwm yam. [6]. CCC daim ntawv pov thawj rau LED tsav tsheb yog qhov yuav tsum tau ua lag luam nkag mus rau hauv kev lag luam thiab yog ib feem tseem ceeb ntawm Tuam Tshoj cov khoom yuav tsum tau ntawv pov thawj. Cov khoom lag luam xws li sawv ntsug- ib leeg LED tsav tsheb thiab cov khoom siv hauv LED tswj yuav tsum tau ntawv pov thawj thiab txuas nrog CCC cim ua ntej lawv tuaj yeem muag, xa tawm, lossis siv hauv Suav lag luam.
