250W
The power supply adopts imported power management chip design, with high reliability, small inrush current, small size (long 70MM* wide 36MM* high 13MM) efficiency up to 96%, power 250W. At the same time, the aluminum substrate design is convenient to install, and the back of the board can be directly affixed to the metal shell for heat dissipation. Reduce device space.
(Voltage regulation resistance is 10K, current regulation is 4.7K)
[Module name] 250W booster constant current module
[Module properties] : Non-isolated BOOST module (BOOST)
[Input voltage] : DC8.5V-48V
[Input current] : 10A (MAX) More than 8A please strengthen heat dissipation
[Static working current] : 10mA(when 12V to 20V, the higher the output voltage, the static current will increase)
[Output voltage] : 10-50V continuous adjustable
12-80V Fixed output (for volume customers)
[Output current] : 10A MAX exceeds 6A, please strengthen heat dissipation (related to input and output pressure difference, the larger the pressure difference, the smaller the output current)
[Constant current range] : 0.2-8A
[Output power] : = Input voltage *10A, such as: input 12V*5A=60W, input 24V*5A=120W,
Input 36V*5A=180W, input 48V*5A=240W,
If more power is needed, two modules can be used in parallel. For example, if the output is 10A, two modules can be used in parallel.
Just set the current of each module to 5A.
[Operating temperature] : -40~+85 degrees (please strengthen heat dissipation when the ambient temperature is too high)
[Operating frequency] : 150KHz
[Conversion efficiency] : 96% (efficiency is related to input, output voltage, current and pressure difference)
[Overcurrent protection] : Yes (input more than 13A, automatically reduce the output voltage, there is a certain range of error.)
[Input reverse protection] : Yes, (less than 5A if you need more reverse current, please insert the diode in the input series)
[Installation method] : 4 3mm screw holes
[Wiring mode] : wiring output
1. Output voltage/current regulation method:
1, Adjust the RV1 potentiometer, according to your battery or LED, set the output voltage to the voltage value you need. Such as 10 string LED voltage adjustment 37V.
2, clockwise adjust the RV2 potentiometer about 30 turns, set the output current to small, connect the LED, adjust the RV2 potentiometer to the current you need. For battery charging, after the battery is discharged, then connect to the output, adjust RV2 to the current you need, (for charging, be sure to use the discharged battery to adjust, because the more the battery remains in power, the smaller the charging current.) Do not adjust the current by short circuit. The circuit structure of the booster module cannot be adjusted by short circuit.
Scope of application:
1, DIY a regulated power supply, the input 12V can be, the output can be 12-50V adjustable.
2, power your electronic equipment, you can set the output value according to your system voltage.
3, as a car power supply, for your laptop, PDA or various digital products power supply.
4, DIY a high-power notebook mobile power: equipped with a large-capacity 12V lithium battery pack, so that your notebook can be lit wherever it goes.
5, solar panel voltage regulation.
6. Charge batteries, lithium batteries, etc.
7. Drive high-power LED lights.
Note: Do not adjust the current by short circuit, the circuit structure of the booster module cannot be adjusted by short circuit, please ensure that the output voltage is greater than the input voltage: when the output current is large, please ensure that the heat dissipation is good; When the load is large, the module should first connect the input voltage, and then connect the load
Note: The installation of electronic modules requires basic knowledge and requires a certain electronic professional foundation and hands-on ability. Please purchase carefully!
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
