100W DC-DC 3V-35V To 3.5V-35V Adjustable Boost Voltage Module

Performance parameters:    

1. Input voltage range: 3-35V DC (Note: the input voltage is less than 4V， voltmeter failure).
2. Input current: 7A.
3. Output voltage range: 3.5-35V DC(please to ensure that output voltage need to above on input voltage).
4. Output current: 6A (max).
5. Output power: 75W (when the input and output voltages greater than 16V up to 100W).
6. Conversion efficiency: 96% (max).
7. Voltmeter range: 4 to 40V， error ±0.1V.
8. Short circuit protection: yes (limit current 14A). (Note: when 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).
9. Input reverse polarity protection: None
10. Dimension: 67 x 42 x 12mm.

Application:    

1. DIY a regulated power supply， 5V input can be output 5-35V adjustable.
2. The power supply for your electronic equipment. For example， 3.7V lithium battery boost to 5V for mobile power; 7.4V or 12V boost to 19V supply power to the laptop
3. As the vehicle power supply for your laptop， PDA or a variety of digital products supply.

Voltmeter manual calibration method:

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.

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.
