Qaanuunka Rarida

Rarid bilaash ah dalabka ka badan $9.9

Qaanuunka Soo Celinta

Hadyada la soo celin karo waxaa la aqbali doonaa 40 maalmood kadib marka la helo alaabta. Hadyada gaarka ah lama soo celin karo. Hadyada la iibsaday kaar hadyo ah waxaa kaliya lagu beddeli karaa; dib u bixid ma aha mid la ogolaaday.

Hadyo Bilaash

Ku soo dhowow Roymall, websitekaaga khaaska ah ee iibsashada hadyada premium-ka ah. Waxaan qiimaynaa taageeradaada waxaana rajeynaa inaan ku muujino mahadnaqintayada iyadoo aan ku darayno hadyo bilaash ah iibsashadaada. Markaad nala iibsato, ma aadan helin oo keliya alaab tayo sare leh oo noloshaada kor u qaadaya, waxaad kaloo heli doontaa hadyo gaar ah oo khaas ah oo la socda dalabka aad sameysid. Diyaar u tahay inaad baadhidato ururkeena oo aad hesho hadyadaada gaarka ah? Raadi ururkeena ee alaabta premium-ka ah, dalabkaaga diiwaan geli, oo sug hadyadaada bilaashka ah oo la socda iibsashadaada.

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

Feature:

This module uses the LM2596 chip, high efficiency (up to 92%), low heat, can be very easily used to above 3A current, in conjunction with the original TI op amp control output current, so the overall output is very stable.
This module uses the original Sanyo low ESR filter capacitor, you can make low ripple voltage to 50mV!
This module uses machine placement, reflow soldering.
This module is an adjustable buck module, the module can be adjusted from the blue adjustable resistor to change the output voltage. Input and output differential pressure is 2V, the minimum can be output 1.23V.
Module indicated IN - (negative input), IN + (positive input), OUT - (negative output), OUT + (positive output), please note must be correct connected, otherwise may cause damage to the module.

Description:

Nature of the module: Non-isolated step-down module
Rectification: Non-synchronous rectification
Input voltage: 7V - 35V
Output voltage: 1.25V - 30V
Output current: Adjustable, 3A (maximum)
Transfer efficiency: 92% (maximum)
Switching frequency: 150KHz
output ripple: 50mV (maximum) 20M Kbps
Load regulation: ±0.5%
Voltage regulation: ±2.5%
Operating temperature: -40°C to +85°C
Dimension: 48 x 23 x 14mm (L x W x H)

Battery charging method:

1. Make sure the battery float voltage and charging current, the module input voltage;
2. Adjustment constant potentiometer, the output voltage is adjusted to about 5V.
3. Use the multimeter (10A current) measuring the output short-circuit current, meanwhile adjust the constant current potentiometer make the output current reaches a predetermined charge current value;
4. Turn lamp current default is 0.1 times charging current (constant current value), if you need to adjust please adjust the turn lamp current potentiometer; (generally doesn't need adjustment)
5. Adjustment constant potentiometer allows the output voltage reaches the float voltage;
6. Connected to the battery and try to charge.
(1,2,3,4,5 steps are for the module input connected to the power supply, output-load battery is not connected.)

LED constant current driver using method:

1. Make sure that the drive LED operating current and maximum working voltage;
2. Adjustment constant potentiometer, output voltage adjusted to about 5V.
3. Use the multimeter (10A current) measuring the output short-circuit current, meanwhile adjusting the constant current potentiometer allows the output current reaches a predetermined LED working current;
4. Adjustment constant potentiometer allows the output voltage reaches the maximum operating voltage LED;
5. Connect LED, test machine.
(1,2,3,4 steps are module input connect to the power supply, output-load is not connected LED lights.)

Package included:

1 x Buck module

This is great module, that can be used both for battery charging and as LED driver. I mostly use it as a driver for these dirt cheap 10w LED: https://goo.gl/g3aBNy

I have already 3 units, work as expected as a led drivers, but one of them I instantly burn by bad polarity input. So be careful about it.
