ANMBEST LTC1871 Converter Adjustable Voltmeter Review

ADVANTAGE: This LTC1871 DC-DC step-up voltage regulator board has a step-up switching regulator on it. The regulator can pass through current up to 10A on itself. It's input voltage range is 3-35V and you can get an output voltage adjustable between 3.5-35V via the trimpot on the board. LCD DISPLAY: You can see the input and output voltage values on the 7 segment displays and you can set this values by looking at 7 segment displays.; voltage display resolution is 0.1V. EASY TO USE: A voltage selection button allows for easy switching between the two. Together with its high multi-turn precision potentiometer this means any desired output voltage within its supply range can be sent without the need of an external test meter. Additionally LED indicators show power and input or output metering. ACCURATE: This product has self-calibration function for the voltage display value! There will never be a problem with inaccurate voltmeters. APPLICATIONS: 1.Used as an ordinary boost module with over-current protection capability; 2.Used as a battery charger; 3.Used as LED constant current driver module.
