75W DC Buck Boost Voltage Converter Constant Current Module Step Power Up

- Brand new      
      - LED power indicator      
      - Module is easy to use, very intuitive      
      - Button to switch measurement of the input or output voltage, and LED indicates the current      
      measurement of the input or output voltage      
      - The voltmeter can be turned off by another button      
      - Module using 12A one piece of high quality inductor, input current can be reached at   7A, similar      
      products on the market are used in ordinary 5A inductor, performance parameters vacuity, so you      
      must pay attention      
      - Special precision voltmeter can also be manually calibrated      
             
                             
         

Performance parameters             
                -Input voltage range: 3-35VDC(Note: the input voltage is less than 4V, voltmeter  failure)              

         

-Input current: 7A

         

-Output voltage range: 3.5-35VDC(please to ensure that output voltage above on  input voltage)

         

-Output current: 6A (max)

         

-Output power: 75W (when the input and output voltages greater than 16V up to  100W)

         

-Conversion efficiency: 96% (max)

         

-Voltmeter range: 4 to 40V, error +-0.1V

         

-Short circuit protection: yes(limit current 14A). (Note: connected to high-power load,  just switched on the impact of current very general meeting current limiting self- locking protection, it is recommended to be switched on firstly, and then access the  load).

         

-Input reverse polarity protection: None (if required, high current diode in series with  the input)

         

-Size:L*W*H = 67*42*16mm

         

-Weight:38g

                    
     
             
                             
         

Application:

            - DIY a regulated power supply, 5V input can be output 5-35V adjustable          

 

         

- The power supply for your electronic equipment. For example, 3.7V lithium boost to  5V for mobile power; 7.4V or 12V boost to the laptop power supply to 19V

         

-As the vehicle power supply for your laptop, PDA or a variety of digital products  supply

         

-Voltmeter manual calibration method

         

-If you feel voltmeter accuracy to meet the requirements, you do not need to perform  the following operations

         

-(1) Output voltage calibration steps

         

-Step 1, adjust the right button so that “OUT” LED lighted, the voltmeter shows the  value of output voltage; Press the right button for more than 2 seconds, release,  voltmeter and “OUT” LED flashes in synchronization so that you enter the output  voltage calibration mode.

         

-Step 2, press the right button (normal speed), the voltage value is adding up a unit;  Press the left button, minus a unit; Due to a unit is less than 0.1V, the minimum  voltage display to 0.1V, so you need to continuously press 1-5 times to see the  voltmeter change 0.1V, how many times voltmeter change 0.1V by pressing the key,  depending on the current display voltage, the higher the voltage, the fewer the  number of press

         

-Step 3, press the right button for more than 2 seconds, release, to exit the output  voltage calibration mode. All parameters set to automatically power down to save

         

-(2) Input voltage calibration steps

         

-Step 1, adjust the right button so that “IN” LED lighted, the voltmeter shows the value  of input voltage; press the right button for more than 2 seconds, release, voltmeter  and “IN” LED flashes in synchronization so that you enter the input voltage calibration  mode

         

-Steps 2 and 3, consistent with the output voltage calibration method
