Product: Buck Boost Converter, DROK DC-DC Buck Boost Converter Voltage Step Up Down Regulator CC CV 5-30V to 0.5-30V Adjustable Power Supply Transformer Module
Brand: DROK
Parameters:
 Input voltage: DC 5~30V  
 Output voltage: DC 0.5~30V
 Output current: 3A (Long-term stable work); 4A (enhance heat dissipation)
 Output power: 30W (natural heat dissipation); 50W (enhance heat dissipation).
 Conversion efficiency: Boost voltage 88~91%; Buck voltage 87~90%（varies by voltage difference and load）
 Working frequency: 180KHZ
 Board size: 68*29*21mm
 
 Using Manual：
 The defaulted output voltage is 12V and the default constant current value is 2A. Please adjust the output constant current value to avoid damaging the load. 
 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 Including:
 1 X Auto Buck Boost Voltage Converter Module

DROK buck boost 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 current.
Setting Value of Constant Current without Multimeter: using one-loop potentiometer with scale to set the constant current value will be more easy.
Protective Function：MOS-input anti reverse protective, under-voltage shutdown protection, output over-current protection.
