Parameters: Input voltage: DC 5~30V Output voltage: DC 0.5~30VOutput current: 3A (Long-term stability work); 4A (strength sinking can reach)Output power: 35W (naturally sinking); 60W (strength sinking).Switch efficiency: Boost voltage 88~91%; Buck voltage 87~90%(It will be changed according to voltage difference and load)Working frequency: 180KHZBoard size: 68*29*21mm Using Manual:The default factory output voltage is set to 6V and the default constant current value is set to 1A. Please adjust the output constant current value to prevent load damage. The taller multi-turn potentiometer is used for adjusting the output voltage. The shorter single turn potentiometer is used for adjusting the constant current value. If you need to increase voltage or current, please adjust the corresponding potentiometers clockwise. To decrease, turn the corresponding potentiometers counter-clockwise. Turn lights in full-charge: A red LED indicates constant current output. A blue LED indicates charging. A green LED indicates that the charging current is less than one-tenth the set value. Application:1. Very suitable for the device of large input voltage range and constant output voltage, such as constant voltage battery, solar power generation, power module.2. Input a constant voltage (such as mobile phone charger or storage battery charging) can get DC 0.5~30V adjustable power. Package Includes:1 X Auto Buck Boost Voltage Converter Module
