1.High-power constant-current function of automatic buck module， can raise and lower voltage， the input voltage may be higher or lower than the output voltage， the output voltage remains constant， automatic voltage regulation.<br />2.Use Kool core inductor， high efficiency and low heat generation， boost efficiency of 90% down to 88% efficiency， maximum input and output current of 5A.<br />3.Large heat sink， <br />4.There have shell and send cover， easy to use and beautiful.<br /><br />Parameters:<br />1. Input voltage: DC 6 ~ 35V( Do positive and negative reversed， or they will damage)<br />2. Output voltage: DC 1.0 ~ 35V (Note: This is the automatic lifting plate platen， the output voltage can be greater than the input voltage to be less than the input voltage)<br />3.Constant adjustment range:0.05A～5A<br />4. Conversion efficiency: 90% (input 12V output 19V / 2.5A when measured， the efficiency with input voltage and output voltage and current related)<br />5. Maximum input current: 7A (Working long hours， please enhance heat dissipation， and leave a certain margin)<br />6. Maximum output current: 5A (Working long hours， please enhance heat dissipation， and leave a certain margin)<br />7. Module size: 70x39x32mm (length x width x height)<br />Directions for use:<br />Access to power， and the output voltage of the module to work with a multimeter voltage gear connected to the output， turn the voltage adjustment potentiometer output voltage adjusted to the desired value. Then transferred to the multimeter 10A current file， it is connected to the output pen positive and negative pen then negative output. And adjust the constant current potentiometer to set the maximum output current value that you expect， the current value displayed on the multimeter is the current value. Upon completion of the normal work load connected.<br /><br /><br />1 x Automatic lifting voltage module<br /><img src="http://img6.eachbuyer.com/x9/p100/cb627_1.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/cb627_2.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/cb627_3.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/cb627_4.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/cb627_5.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/cb627_6.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/cb627_7.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/cb627_8.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/cb627_9.jpg" />
