DEVMO 2 PCS LTC1871 Boost Power Module High Power DC-DC 100W Adjustable Output 3.5-35v Step up Power Supply Converter Module Board with LED Digital Display Voltmeter

The additional advantage of function: 1. On board LED work indicating lamp, the working state is more intuitive. 2.Switch digital tube lights, switch measuring input and output voltage. (the on board voltage indicator "IN" show input voltage, the "OUT" bright display output voltage). 3.This product has voltage meter automatic calibration function, it will not exist the problem of accurate voltage meter!

• 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, suitable for LED strips and modules, but not for raw LEDs.
• Input: 3-35V DC 9A, Output: 3.5-35V DC 6A, Max Power: 100W when input and output both exceed 20V, otherwise 65W.
• Conversion Efficiency: Up to 96%. Low input voltage or a large difference between input and output voltage will degrade the current capacity and efficiency.
• Output voltage must be greater than input voltage, do not apply reverse polarity voltage, voltmeter works only when input is >= 4V.
• Length x width x high =67*43*12MM, It's brand new, good quality & high performance.
