Charger kuaj tus qauv
Oct 04, 2019| Charger kuaj tus qauv
AC input voltage: charger fais fab input 100VAC/240VAC (domestic standard), kuaj DC davhlau ya nyob twg voltage, voltage yuav tsum yog 5V ± 0.25V
Voltage / zaus: rated input voltage yog AC220V, qhov tso cai input voltage ntau yog 100VAC / 240VAC (tus qauv hauv tsev). Qhov zaus yog 47HZ-63HZ
Tawm tswv yim tam sim no (ntawm tag nrho cov load): Thaum input AC voltage AC220V / 50HZ, qhov siab tshaj plaws input tam sim no yuav tsum tsawg dua 0.15A
Ua hauj lwm efficiency: ua hauj lwm efficiency (tso zis hwj chim / input zog) Ntau tshaj los yog sib npaug zos rau 60% thaum inputting 100VAC / 240VAC (tus qauv hauv tsev) thiab tso zis 500mA
Surge tam sim no: Nyob rau hauv cov ntaub ntawv ntawm khau raj txias, qhov siab tshaj plaws inrush tam sim no yog tsawg dua 25A nyob rau hauv 10mS tom qab inputting 220V voltage
Input tsis load zog noj: tsis load zog noj tsawg tshaj li 300mW
Rated tso zis voltage: DC5.0V
Cov zis hluav taws xob / tam sim no ntau: voltage DC5.0V ± 0.25V tam sim no: Ntau dua lossis sib npaug rau 450mA
Cov zis ripple: Tsawg dua lossis sib npaug rau 200mV; Kev sim txoj kev: Txuas ib qho oscilloscope bandwidth mus rau 20MHz rau cov zis ntawm lub charger nyob rau hauv ib txwm ua haujlwm load, thiab txuas 104pF ceramic capacitor thiab 10Uf electrolytic capacitor rau cov zis.
Kev tiv thaiv luv luv: Nws tuaj yeem ua kom ntseeg tau tias cov khoom yuav tsis ua rau hluav taws kub lossis muaj kev puas tsuaj thaum cov zis tawm luv luv. Qhov luv-circuit tam sim no yuav tsum tsis pub tshaj 950mA.
Kev tiv thaiv overvoltage: Tus nqi tiv thaiv overvoltage yuav tsum tsis pub tshaj 8V ntawm qhov siab tshaj plaws. Thaum lub Circuit Court malfunctions thiab cov zis voltage nce txawv txav, lub tiv thaiv Circuit Court yuav cia li pib txo cov zis voltage.
Kev tiv thaiv overcurrent: charger fais fab input 100VAC / 240VAC (tus qauv hauv tsev) nrog cov khoom ntsuas ntsuas, lub load ntawm lub charger zoo li overloaded, lub charger yuav tsum tsis txhob puas, lub overload tiv thaiv tam sim no ntawm lub charger yog tsawg dua los yog sib npaug rau 700mA. Thaum lub overload raug tshem tawm, lub charger yuav tsum rov pib dua li qub tso zis.
Rov qab tam sim no: tsis pub ntau tshaj 5mA tam sim no los ntawm sab ntawm lub xov tooj mus rau lub charger
Instantaneous impulse voltage: Thaum siv fais fab, lub charger transient surge voltage yuav tsum tau tswj hauv qab 5.5V.
Cov dej ntws tam sim no: tsis muaj Y capacitor, tsawg dua 0.05mA
Qhov tshwm sim / kev sib dhos tiag tiag: Qhov pom qhov ntev yog ua raws li kev soj ntsuam thiab kev qhia tshwj xeeb, thiab qhov siab tshaj plaws thiab qhov sib txawv tsis ntau tshaj 0.25mm. Thaum lub xov tooj siv tiag tiag, nws tsis tshwm sim xoob thiab tsis tuaj yeem muab tso rau hauv tag nrho, thiab kev ua haujlwm zoo li qub.
