20W DC 3.6V-30V Buck Boost Converter, 2 Modes PCB, Dual Output Power Supply Module

Features:1.Working Mode 1: Positive input voltage and positive and negative output voltage.Positive and negative voltages must be used simultaneously; otherwise, the negative voltage will not be output.
2.Working Mode 2: Positive input voltage, positive output voltage, as a common buck-boost converter.
3.PCB Board: The PCB board makes the module robust and durable, ensuring a better user experience and a long service life.
4.Wide Application: This power supply module is mainly used for automotive power supplies, instrument power supplies, LCD backlight power supplies, etc.
5.Easy to install: Comes with a compact size and light weight, making installation quick and easy.

How to Use:Q1: Why is the output voltage lower than the rated voltage? A1: This could be due to the load being too large or the power supply being too small. Q2: Why is the negative voltage not outputting, or why is the output too low? A2: The negative voltage cannot be used alone. When using a negative voltage, the same load must be applied to the positive voltage end.
