Brand: FainWan

Model: LTC1871-2PCS

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.

• No user/operator instructions or data sheets.Find the download data by yourself, please make sure you consider whether you know the operation before buying. Size: 68x42x14mm, LTC1871 IC with External MOSFET.
• Conversion Efficiency: Up to 96%. Low input voltage or a large difference between input and output voltage will degrade the current capacity and efficiency.
• Boost voltage to a stable regulated output. Useful for a wide range of applications, such as powering 5V USB devices from a 3.7V lithium cell, powering higher powered electronics from a 12V battery, and a wide range of automotive and electronic projects. Constant voltage regulation, not for raw LEDs.
• Button to switch measurement of the input or output voltage, and LED indicates the current measurement of the input or output voltage
• The nixie tube can be turned off by another button. Mentioned states are able to be memorized, is not lost even if the power is disconnected. (On-board marked "IN" LED is turned on, the nixie tube display input voltage value, "OUT" LED bright display is the output voltage value).
• Output voltage must be greater than input voltage, do not apply reverse polarity voltage, voltmeter works only when input is >= 4V.
