DC-DC Auto Buck Boost Voltage Converter Step Down/ Step Up

voltage converter input voltage range is DC 5-30V, output voltage range is DC 0.5-30V, output current of natural cooling is 3A, with strength sinking output current can reach 4A.Automatically Boost or Buck: no matter the input voltage is higher than 12V or lower than 12V, the voltage can be steadily output 12V.Constant Current: input any value within DC 5-30V, can directly charge storage battery, lithium battery, AA battery; besides, it can adjust LED brightness of constant The higher multitier potentiometer is used for adjusting the output voltage; the shorter one-loop potentiometer is used for adjusting constant current value. If you need to increase voltage /current, please adjust the corresponding potentiometers clockwise, whereas counter-clockwise adjustment.Setting Value of Constant Current without Multimeter: using one-loop potentiometer with scale to set the constant current value will be more easy.MOS-input anti reverse protective, under-voltage shutdown protection, output over-current protection.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: 180KHZThe factory output voltage defaults 12V, constant current defaults 2ATurn lights in full-charge:Red lighted when the module is in constant status. Blue lighted when the module is charging. Green lighted when the charging current is less than one-tenth constant current value you set, charging is finished.Very suitable for the device of large input voltage range and constant output voltage, such as constant voltage battery, solar power generation, power module.Input a constant voltage (such as mobile phone charger or storage battery charging) can get DC 0.5~30V adjustable power.Constant Current besides, it can adjust LED brightness of constant currentColour:blueMaterial:plasticsize:68 * 29 * 21mmPackage Contents:1x Auto Buck Boost Conveter 60WNote: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
