Product Description: Automatic boost module provide a stable power supply.Applicable to unstable voltage source or voltage conversion. Performance parameters: Input voltage range:3~35VDC(Note: the input voltage is less than 4V, voltmeter failure) Input current:9A (max) 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 20V up to 128W) Conversion efficiency: 96.4% (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: 67 * 43 * 12mm (L x W x H) Use manual: Connect load at OUT+ and OUT- at first.Please note the positive and negative. Connect power supply at IN+ and IN-.Please note the positive and negative. Press the button to switch the display input or output voltage value. Warm tip: When the high power load is connected, because the shock current of the start-up is very limited, it is recommended to start up and then connect the load. 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. Frequency asked questions: 1>. Can it output 35V at 6A? Q : No,it can not.The output max is 100W.Only 75W for stable operation.
