250W High Power Boost Constant Voltage Constant Current Car Laptop LED Driver

Module name: 250W booster constant-current module Module nature: Non-isolated BOOST module Input voltage: DC10V-40V Input current: 6A (MAX) Static working current: 10mA(when 12V litre 20V, the higher the output voltage, the higher the static current will be) Output voltage: 10-50V continuous adjustable (default output 19V shipment.) Output current: 6A MAX more than 4A, please strengthen the heat dissipation (related to the input and output pressure difference, the greater the pressure difference, the smaller the output current) Constant current range: 0.2-6A Output power: = Input voltage *6A, for example: input 12V*6A=72W, input 24V*6A=144W, Enter 36V*5A=180W, enter 48V*5A=240W, Operating temperature: -40~+85 degrees (please strengthen the heat dissipation when the ambient temperature is too high) Working frequency: 150KHz Conversion efficiency: 92-96% (efficiency is related to input, output voltage, current, differential pressure) Input backconnect protection: Yes, (less than 5A, if you need more backconnect current, please put the diode in the input string) Installation: 4 3mm screw holes Wiring mode: Wiring output Module size: length 70mm width 36mm height 13mm Module weight: 50g Quantity：1pcs 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 mode. The circuit structure of the boost module cannot be adjusted in a short-circuit mode. Instructions for use: 1. VIN+ is the positive pole of input power, VIN- is the negative pole of input power, 2. OUT+ is the positive pole of the output power, and OUT- is the negative pole of the output power. 3. Adjustable range of constant voltage: DC10-50V (small clockwise, large counterclockwise), 4. Adjustable range of constant current: 0.2A-6A (smaller clockwise, larger counterclockwise), 5. When the input current exceeds 2A, heat dissipation shall be strengthened (aluminum substrate is attached to the flat metal parts). 6. Input voltage shall not be less than 10V or more than 40V, 7. Input large current shall not exceed 6A, power shall not exceed 240W, 8. Ensure that the input voltage is lower than the output voltage by more than 2V when using. 9. Before switching on the load, please adjust the required voltage and current when there is no load (the constant current space-time load voltage should be increased by 3-5V). 10. When using the switching power supply or other secondary power supply, please ensure that the power of the power supply should be more than one time of the power power of this module. Notes: 1. Input and output cannot be reversed. 2. Input, output voltage and current should not exceed a large value during operation, so as not to damage the power supply. 3. Pay attention to ventilation and heat dissipation when working for a long time with full load, so as to extend the service life of the power supply. 4. Pay attention to dust and moisture. Application Scope: 1. DIY a stable power supply, input 12V can be, output can be adjustable 12-50V. 2. Power your electronic devices, and set the output according to the voltage of your system. 3. Power your laptop, PDA or any other digital device as an on-board power source. 4. DIY a high-power notebook mobile power supply: With a large capacity of 12V lithium battery pack, your notebook can be lit up wherever you go. 5. Stabilize the pressure of solar panels. 6. Charge the battery, lithium battery, etc.
