Kudzoserwa & Kuchinjaniswa Mutemo
Tinogamuchira chete zvinhu zvakatengwa kubva roymall.com. Kana iwe ukatenga kubva kune vedu vekutengesa kana vamwe vatengesi, haugone kuzvidzosera kwatiri. Zvinhu zvekupedzisira kutengeswa kana zvipo zvemahara hazvigamuchirwe kudzoserwa.Kuti ukwanise kudzosa, chinhu chako chinofanira kunge chisina kushandiswa uye chiri mumamiriro akafanana neawachigamuchira. Chinofanirawo kunge chiri mupakeji yepakutanga.Mushure mekugamuchira mirairo yekudzosa kubva kwatiri, ndapota pakeja zvinhu zvako zvakadzoserwa uye donhedza pasuru yako kuposvo yemuno kana imwe courier.Tichagadzirisa chinhu chako chakadzoserwa kana kuchinjaniswa mukati memazuva matatu kusvika mashanu ekushanda mushure mekunge tagamuchira. Mari yacho ichagadziriswa uye yozopihwa otomatiki kune yako yekutanga nzira yekubhadhara.Hapana kudzoserwa kana kuchinjaniswa kunogona kugamuchirwa kana chigadzirwa chakagadzirwa netsika, kusanganisira saizi yakagadziridzwa, ruvara rwakagadziridzwa, kana kudhinda kwakagadziridzwa.Unoda rumwe rubatsiro, ndapota taura nesu. service@roymall.com kana Whatsapp: +86193598494712.Mutemo Wekudzoserwa Mari
Uchawana mari yakazara kana 100% kiredhiti yechitoro mushure mekunge tagamuchira pasuru yakadzoserwa uye tikaiona. Mari yacho ichagadziriswa uye yozopihwa otomatiki kune yako yekutanga nzira yekubhadhara.Ndapota cherechedza kuti mitengo yekutumira uye chero mitero kana mubhadharo haidzoserwe. Mari yekuwedzera yekutumira haidzoserwe kana pasuru yatotumirwa. Iwe une basa rekubhadhara aya mitero uye isu hatikwanise kuregerera kana kudzosera, kunyangwe odha ikadzoserwa kwatiri.Kana tangogamuchira uye tasimbisa chinhu chako chakadzoserwa, tichakutumira email kukuzivisa kuti tagamuchira chinhu chako chakadzoserwa. Tichakuzivisawo nezvekubvumidzwa kana kurambwa kwemari yako.Kana uine chero matambudziko maererano nemaitiro ekudzoserwa mari, ndapota taura nesu. service@roymall.com kana Whatsapp: +8619359849471
Features:
nt- Fixed turn lamp current is 0.1 times the current value ( Used to identify whether the battery is fully charged When charging).
t- Made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20u00b0C to 100u00b0C constant current 1A, temperature drift less than 1%). Particularly suitable for LED.
t- High output current, the max output current can reach 8A.
t- Four high frequency capacitance, can lower output ripple, enhance the work stabilization.
t- Double heat sink design. MOS schottky diode independent heat sink,which heat dissipation is good,and wonu2019t affect each other.
t- Using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever.
t- 3296 multiturn potentiometer,high accuracy voltage and current regulation, good stability.
t- Double color lamp, working condition be clear at a glance
t- Voltage and current are adjustable,wich effect is good.
ntParameters:
nt- Module Properties: Non-isolated step-down constant current, constant voltage module (CC CV) charging module
t- Input Voltage: DC 7-32V
