1. The power management chip is designed with high reliability, small surge current, small size, the efficiency is as high as 96%, and the power is 250W. 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)2. 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)3. Output voltage: 10-50V continuously adjustable, 12-80V fixed output (for batch customers). Output current: 10A MAX, if more than 6A, please strengthen heat dissipation (related to the input and output pressure difference, the greater the pressure difference, the smaller the output current). Constant current range]: 0.2-8A4. Output power: = input voltage*10A, such as: input 12V*=60W, input 24V*=120W, Input 36V*=180W, input 48V*=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.5. 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 will be automatically reduced with a certain range of error.)[Input reverse connection protection]: Yes, (less than the reverse connection current if you need more, please connecta diode in series with the input)[Installation method]: 4 3mm screw holes[Wiring mode]: Wiring output[Module weight]: 50 gramsOutput voltage/current adjustment method:1. Adjust the RV1 potentiometer, according to your battery or LED, set the output voltage to your needsThe voltage value. For example, the voltage of 10 LED strings is adjusted to 37V.2. Turn the RV2 potentiometer clockwise about 30 turns, set the output current to, and connect it LED, adjust the RV2 potentiometer to the current you need. For battery charging, discharge the battery completely. Then, connect to the output and adjust RV2 to the current you need. (It must be used up when charging the battery should be adjusted correctly, because the more power left in the battery, the lower the charging current. ) Please do not use adjust the current in a short-circuit mode, and the circuit structure of the boost module cannot be adjusted in a short-circuit mode.colour:WhiteMaterial:Aluminum + plasticsize:70 x 36 x 13mmPackage Contents:1 x 250W high power boost constant voltage moduleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
