Qaanuunka Rarida
Waxaan kuu diri doonaa alaabta marka aan helno dalabkaaga oo aan hubino inay si amaan ah gaadhaan. Faahfaahinta rarida waxaa lagu siin doonaa iimaylka xaqiijinta.Inta badan, dalabka waxaa lagu qabanayaa 2 maalmood. Xaaladaha gaarka ah, waxaa laga yaabaa inuu dib u dhaco sida soo socota: Markaad dalabto Sabti, Axad ama fasaxyada dawliga ah, waxaa laga yaabaa inuu dib u dhaco 2 maalmood.Guud ahaan, waxay qaadataa 5-7 maalmood shaqo (Isniin ilaa Jimco) iyadoon la dhacin ka dib u dhaca duulimaadka ama sababaha kale ee deegaanka.Maadaama adeeggeenu rarida uu aduunka oo dhan yahay, waqtiyada rarida waxay ku xiran yihiin goobtaada, sidaa darteed waxay qaadan kartaa waqti dheer haddii aad ka mid tahay degmooyinka fog ama dalalka.
1. Qaanuunka Soo Celinta & Beddelka
Waxaan aqbalnaa oo keliya alaabta laga iibsaday roymall.com. Haddii aad ka iibsato qaybaha aan ku leenahay ama iibiyeyaasha kale, kuma soo celin kartid aanaga.Alaabta iibka dambe ama hadyada bilaashka ah lama aqbali karo soo celin.Si aad u qalanto soo celin, alaabtaagu waa inaysan isticmaalin oo ay tahay xaaladda aad heshay. Waa inay kaloo ku jirtaa qalabka asalka ah.Kadib markaad hesho tilmaamaha soo celinta, urur alaabtaada oo ku dheji boostada ama kooreer kale. Waxaan ku qabanaynaa soo celinta ama beddelka alaabta 3-5 maalmood shaqo kadib marka aan helno. Lacagta dib loo celiyo waxaa lagu qabanayaa si toos ah oo lagugu celin doono qaabka lacag bixinta asalka ah.Ma jirto soo celin ama beddel lagu aqbali karo haddii alaabta la sameeyay si gaar ah, oo ay ku jiraan cabbir gaar ah, midab gaar ah, ama daabacad gaar ah.Haddii aad u baahan tahay caawimaad dheeraad ah, fadlan nala soo xiriir. service@roymall.com ama Whatsapp: +447549870296
2.Qaanuunka Lacagta Dib u celinta
Waxaad heli doontaa lacag dib u celin oo buuxda ama 100% kreeditka dukaanka kadib marka aan helno alaabta la soo celiyay oo aan hubino. Lacagta dib u celinta waxaa lagu qabanayaa si toos ah oo lagugu celin doono qaabka lacag bixinta asalka ah.Fadlan ogow in khidmadaha rarida iyo wax kasta oo khidmadaha ah aan dib loo celin karin. Khidmadaha rarida ee dheeraadka ah lama soo celin karo marka boostadu la raray. Waad mas'uul ka tahay bixinta khidmadahan, mana awoodno inaan ka reebno ama dib ugu soo celino, xitaa haddii dalabku noo soo laabto. Markaan helno oo aan xaqiijinno alaabtaada la soo celiyay, waxaan kuu soo diri doonnaa iimayl si aan kuu ogeysiinno inaan helay alaabtaada la soo celiyay. Waxaan kaloo kuu ogeysiin doonnaa ansixinta ama diidmada dib u celintaada.Haddii aad dhibaato ka qabato habka dib u celinta, fadlan nala soo xiriir. service@roymall.com ama Whatsapp: +447549870296

Features:
- Fixed turn lamp current is 0.1 times the current value ( Used to identify whether the battery is fully charged When charging).
- Made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20°C to 100°C constant current 1A, temperature drift less than 1%). Particularly suitable for LED.
- High output current, the max output current can reach 8A.
- Four high frequency capacitance, can lower output ripple, enhance the work stabilization.
- Double heat sink design. MOS schottky diode independent heat sink,which heat dissipation is good,and won't affect each other.
- Using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever.
- 3296 multiturn potentiometer,high accuracy voltage and current regulation, good stability.
- Double color lamp, working condition be clear at a glance
- Voltage and current are adjustable,wich effect is good.
- Output Voltage: (1) DC 1.2-28V continuously adjustable. (2) Fixed output:Choose between 0.8v-28v
- Output Current: 8A (when power tube"s temperature exceeds 65 degrees, please add cooling fan)
- Constant Current Range: 0.2-8A (Adjustable)
- Turn Lamp Current: Constant current value * (0.1), turn the lamp current and constant value linkage, such as constant current value is 3A, turn the lamp current is set to a constant current is 0.1 times (0.1 * 3A = 0.3A)
- Output Short Circuit Protection: Yes, constant current
- Input Reverse Polarity Protection: None
- Output Prevent Backflow: None
- Wiring: Terminal
- No-Load Current: Typical 20mA (24V switch 12V)
- Load Regulation: ± 1% (Constant)
- Voltage Regulation: ± 1%
- Dynamic ResponseSpeed: 5% 200uS
- Potentiometer Adjustment Direction: clockwise (increase) , counterclockwise (decrease), the potentiometer(CV) closed to the input voltage is used to regulate voltage, the potentiometer(CC) closed to output voltage is used to regulate current (CC)
- Operating Temperature: Industrial grade (-40 °C to +85 °C) (please note the actual use of the power tube temperature , high temperature heat strengthened)
- Indicator: dual color indicator, charging indicator light is red, the green light means fully charged (No load is green)
- Size: Approx. 65 x 47 x 23.5mm/2.56 x 1.85 x 0.93""
- Precision of Constant Current and Temperature: On the actual test, the module temperature from 25 degrees to 60 degrees, the constant current value change is less than 5% (5A constant current value)
- Output Short Circuit Protection: Yes,Constant current (the current setting constant current value)
I love these supplies. I used them to build a variable DC supply for my bench. I changed the pots for panel mount 10 turn pots and fed these supplies(3) with a high current 24V supply. Most of the parts for this project were source from banggood including the laser to engrave the front panels.
Incrivelmente pequeno, mas muito bom! A encomenda chegou sem atrasos e sem problemas, nada danificado e bem embalado. Já testei e fiquei muito contente, coloquei na entrada 22 Volts DC retirados da minha fonte e foi regulando a saída e tirei várias voltagens como podem ver nas fotos. Por isso recomendo, não aqueceu e por fim digo que é um bom regulador de DC para DC. Temos que ter atenção em não ultrapassar a voltagem máxima permitida pelo fabricante.
