Aluminum plate 250W high power step-up constant current voltage LED driver power supply for car laptop
[ Module name] 250W boost constant current module
[ Module properties: non-isolated step-up module (BOOST)
[ ] Input voltage : DC8.5V-48V
[ ] Input current : 10A (MAX) exceeds 8A please enhance heat dissipation
[ ] Quiescent current : 10mA (12V liter 20V , the output voltage , the higher the current will increase too quiet )
[ ] Output voltage : 10-50V continuously adjustable (The default output 19V shipping, For other voltages , please explain to the treasurer . )
12-80V fixed output ( for volume customers )
[Output current ] : 10A MAX exceed 6A please enhance heat dissipation ( input, output pressure related to the pressure the greater the output current is smaller )
[ Constant ] range : 0.2-8A
[ Output ]: = input voltage * 10A, such as: input 12V * 5A = 60W, input 24V * 5A = 120W,
Input 36V * 5A = 180W, Input 48V * 5A = 240W,
For more power , the two modules can be used in parallel, such as the output to be 10A, two modules can be used in parallel ,
The current per module can be transferred to 5A .
[ Temperature ]: -40 to + 85 degrees ( ambient temperature is too high , please enhance heat dissipation )
[ Operating frequency ] : 150KHz
[ ] Conversion efficiency : up to 96% ( efficiency and input and output voltage, current , pressure -related )
[ Overcurrent protection ]: Yes ( input exceeds 13A, automatically reduces the output voltage , have a range of error . )
[ Input reverse polarity protection ]: Yes, ( less than 5A as the need for more in the reverse current in the input string into the diode )
[Installation method: 4Pcs 3mm screw holes
Connection method : Connection Output
[ Module size ] : Length 70mm width 36mm height 13mm
[ Single ] module : 50 g
An output voltage / current regulation method :
1 , adjust potentiometer RV1 , according to your battery or LED, the output voltage is set to the voltage value you need . 10 LED string voltage regulator such as 37V.
2 , clockwise adjustment potentiometer RV2 about 30 laps , the output current is set to a minimum , connected LED, adjust potentiometer RV2 to the desired current. After charging for battery , the battery fully discharged , and then to output , adjust to your desired current RV2 , ( be sure to use for charging batteries completely discharged before being allowed to transfer , because the battery power is left in the more , the charge current is smaller. )Please do not use the short-circuit current transfer mode , the circuit structure of the booster module can not be adjusted by way of a short circuit .
Applications:
1, DIY a power supply, 12V can input and output can 12-50V adjustable.
2 , the power supply for your electronic device , according to your system can set the output voltage value .
3 ,As car power supply for your laptop , PDA or a variety of digital products supply.
4, DIY a mobile notebook power supply: 12V coupled with high-capacity lithium battery pack , so you can go where light where books .
5 , solar panel regulator .
6 , to the battery , rechargeable lithium batteries .
7 , driving high-power LED lights.
