2X - Auto Buck Boost Voltage Converter Step Down/ Step Voltage Regulator Adjustable 5V-30V to 0.5-30V

2X - Auto Buck Boost Voltage Converter Step Down/ Step Voltage Regulator Adjustable 5V-30V to 0.5-30V Description

voltage converter input voltage range is 5-30V, output voltage range is 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 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: 0.5~30V
Output current: 3A (Long-term stability work); 4A (strength sinking can reach)
Output power: 35W (naturally sinking); 60W (strength sinking).
efficiency: Boost voltage 88~91%; Buck voltage 87~90%(It will be changed according to voltage difference and load)
Working frequency: 180KHZ
The factory output voltage defaults 12V, constant current defaults 2A
Turn lights in full-charge:Red lighted when the module is in constant status. 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 constan
