Switching power supply 250 W, LED controller module with constant current, max. 10 A Description: Premium 250W non-insulated constant current module (BOOST) Input voltage: 8,5-48 V; Output voltage: 10-50 V (continuously adjustable) Output current: 10A (MAX) (please increase heat dissipation if it is more than 6A) Constant output current: 0.2 - 8A (shorten output to adjust current) Voltage regulation resistance: 10 K, current regulation resistance: 4,7 K Specification: Input Voltage: DC8.5V-48V Input current: max. 10A, please enhance heat dissipation if it exceeds 8A Static operating current: 10mA (when 12V voltage rises do 20V, the higher the output voltage, the static current will increase) Output voltage: smooth adjustment 10-50 V Output current: max. 10A, please enhance heat dissipation if it exceeds 6A DC Range: 0,2-8A Operating temperature: -4085 degrees Operating Frequency: 150KHz Conversion efficiency: 96 Overcurrent protection: yes Entry protection: yes Assembly method: 4 pcs. 3mm screw holes Size (L. x width x H ): approx. 70mm x 36mm x 13mm Weight: 50g Application: 1. DIY power supply, 12V input, output can be adjusted 12-50V. 2. Powering the electronic device and setting the output value according to the system voltage. 3. Vehicle mounted power supply, powers laptop, PDA or various digital products. 4. DIY High Power Notebook: With 12V High Capacity Lithium Battery 5. Voltage regulator of solar panels. 6. batteries, lithium batteries, etc. 7. Drive high-power LED diodes. Output voltage/current regulation method: 1. Adjusting the RV1 potentiometer and setting the output voltage to the voltage needed according to the battery or LED diode, such as the LED diode, is adjusted do 37 V. 2. Rotate the potentiometer clockwise by about 30 revolutions, set the output current to a minimum, connect the LED diode and set the potentiometer to the required current. In order to charge the battery, after the battery is discharged, connect it do output and adjust the current do of the required intensity. (Do charge be sure to use a discharged battery do adjust the battery, because the battery remains larger the smaller the charging current. ) Do not use methods such as short circuit do current regulation. The circuit structure of the boost module cannot be adjusted in a short-circuit manner. The package includes: 1 piece DC module
