DC Buck Converter, Max 7A DC-DC 8-60V to 3-32V Digital Volt Transformer Step-Down Voltage Regulator with LCD Display, Shell

Description: This step-down voltage regulator can regulate voltage more convenient and fast compared with similar potentiometer, it can withstand 100,000 presses. Easy to operate, using button adjustable voltage, left button to reduce the voltage, the right button to increasing voltage. press button one time can adjust 0.04V voltage, press and hold more than 1 second to quickly adjust voltage. Designed with LCD display screen, voltage and current can be displayed simultaneously. Also, it equipped with a transparent acrylic shell, easy to read while protecting the module. Specifications: Input Voltage: DC 8V~60V (Recommended  within 55V,  Input voltage must be higher than the output voltage 1V above)  Output Voltage: DC 3V~32V Continuously adjustable (It can save the last set voltage automatically)  Output Current: Max 7A (Recommended use within 5A, Please pay attention to heat dissipation.)  A ccuracy: 1%, the voltage three bits display, the current two bits display, the unit is "A".  Input Anti-reverse Protection: Yes  Short Circuit Protection: Yes  Conversion Efficiency: Max up to 95%  Load Regulation S(I):  ?0.8%  Voltage Regulation S(U):  ?0.8%  Size: 62 × 44 × 18mm / 2.59 × 1.73 × 0.7in Weight: 67g Package Includes: 1 × Step-Down Module Kit 1 × Acrylic shell Note: If it is used for charging, after charging, please first disconnect the battery end and then the input end to prevent the battery from damaging the module by backflow. Or at the output end add a diode preventing backflow.
