Description: High efficiency non-isolated boost module, output voltage can't be less than input voltage. Four screw holes in the board enable you to mount the module more conveniently and easier. Over-current for protection: yes (if more than 13A, it will automatic reduce the output voltage, a certain range of errors). Input reverse connection for protection: yes, (less than 5A if you need more reverse connection current in the input string). Applications: DIY a power supply, 12V input and output 12-50V adjustable; The power supply for your electronic device , according to your system can set the output voltage value .As car power supply for your PDA ,LED lightsor a variety of digital products supply.DIY solar panel regulator. Specifications: Material: metal. Color: show as pictures. Size: 70*36*13mm. Module properties: non-isolation boost module (BOOST). Input voltage: DC 8.5-48V. Input current: 10A (MAX), if exceeds 8A, please strengthen the heat dissipation. Static working current: 10mA (12V up 20V, the higher the output voltage is, the higher the static current will increase). Output voltage: 10-50V continuous adjustable if necessary (default output delivery). Output current: 10A MAX, if over 6A please strengthen heat dissipation. (Related to the input and output voltage difference, the larger the voltage difference is, the smaller the output current is). Constant current range: 0.2-8A. Work frequency: 150KHz. Over-current for protection: yes (if more than 13A, it will automatic reduce the output voltage, a certain range of errors). Input reverse connection for protection: yes, (less than 5A if you need more reverse connection current in the input string). Install mode: 4 3mm screw holes. Notes: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Package include: 1 * Step-up Module.
