DC Boot DC Converter Constant Current Power Supply Module 250W 10A LED Driver Panel Converter Mounting Module

The power supply adopts imported power management chip design, which has high reliability, small surge current, small size (length 70MM * width 36MM * height 13MM), the efficiency is as high as 96% , and the power is 2 50W . At the same time, the aluminum base plate is designed for easy installation, and the back of the plate can be directly attached to the metal shell to dissipate heat. Reduce equipment space.

(The voltage regulation resistance is 10K, and the current regulation is 4.7K)

[Module name] 250W boost constant current module

[Module nature]: Non-isolated boost module (BOOST)

[Input voltage]: DC8.5V-48V

[Input current]: 10A (MAX) over 8A, please strengthen heat dissipation

[Static working current]: 10mA (when 12V rises to 20V, the higher the output voltage, the static current will increase)

[Output voltage]: 10-50V continuously adjustable

12-80V fixed output (for batch customers)

[ Output current]: 10 A MAX, if more than 6A, please strengthen heat dissipation (related to the 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 you need more power, you can use two modules in parallel. For example, if the output is 10A, you can use two modules in parallel.

Just adjust the current of each module to 5A.

[Working temperature]: -40~+85 degrees (please strengthen heat dissipation when the ambient temperature is too high)

[Working frequency] : 150KHz

[Conversion efficiency]: 96% (efficiency is related to input, output voltage, current, and pressure difference)

[Overcurrent protection]: Yes (when the input exceeds 13A, the output voltage is automatically reduced, and there is a certain range of error.)

[Input reverse connection protection]: Yes, (less than 5A, if you need more reverse connection current, please put a diode in series in the input)

[ Installation method]: 4 3mm screw holes

[Wiring mode]: Wiring output

[Module size]: length 70mm width 36mm height 13mm

[Module weight]: 50 grams

1. Output voltage/current adjustment method:

1. Adjust the RV1 potentiometer, according to your battery or LED, set the output voltage to the voltage value you need. For example, the voltage of 10 LED strings is adjusted to 37V.

2. Adjust the RV2 potentiometer clockwise about 30 turns, set the output current to low, connect the LED, and adjust the RV2 potentiometer to the current you need. For battery charging, after the battery is discharged, connect to the output and adjust RV2 to the current you need. (When charging, you must use the discharged battery to adjust it, because the battery has more power. More, the lower the charging current.) Please do not adjust the current in a short-circuit method, and the circuit structure of the boost module cannot be adjusted in a short-circuit method.

Application scope:

1. DIY a regulated power supply, input 12V, output can be adjusted from 12-50V.

2. To supply power to your electronic equipment, you can set the output value according to your system voltage.

3. As a vehicle power supply, power your laptop, PDA or various digital products.

4. DIY a high-power notebook mobile power supply: equipped with a large-capacity 12V lithium battery pack, so that your books can be bright wherever you go.

5. The solar panel voltage stabilizes.

6. Charging batteries, lithium batteries, etc.

7. Drive high-power LED lights.
