The XY-SK120X is a 120W CNC adjustable DC-DC buck-boost module that converts a 6-36V input into a fully adjustable 0-36V output at up to 6A. As a buck-boost design it can step voltage up or down, so the output stays at your set value even when the input is higher or lower, which suits batteries, solar panels, and variable DC sources.

It runs in constant voltage and constant current (CV/CC) modes and supports MPPT solar charging to draw more usable power from a panel. A color LCD shows input voltage, output voltage, current, and power with 0.01V and 0.001A resolution, and ten memory groups let you save and recall favorite settings. Protections include reverse connection, under-voltage, over-voltage, over-current, over-power, and over-temperature.

Use it as a compact bench power supply, a battery charger, a solar charge controller, or a power source for DIY electronics and workshop projects. The module is rated for 120W, and the manual notes that up to 150W is possible only with optimal cooling, so allow good airflow for sustained high-power use.
