XL4016 Step-Down DC-DC Buck Converter 300W

This step-down converter module with the XL4016 reduces a DC voltage of 7 to 40 V to 1.2 to 35 V. Two multi-turn potentiometers set the output voltage (CV) and the current limit (CC). This makes it suitable as a power supply for setups, as a constant current source for LEDs, for example UV LEDs in a resin printer, or as a voltage converter for devices.

Recommended Accessories:

• Stranded Wire 1.5mm² 16AWG Red Halogen-free
• Stranded Wire 1.5mm² 16AWG Black Halogen-free

Features:

• Potentiometer on the input side: output voltage (CV)
• Potentiometer on the output side: current limit (CC)
• Turning clockwise increases the value, anticlockwise decreases it
• Two-colour LED: green without current limiting, red when current limiting is active
• 2 heat sinks on the power components, connection via 4-pin screw terminal
• 8 A and 300 W are maximum values; for continuous operation at high current, allow a margin and provide airflow

Application Examples:

• Constant current source for LEDs and UV LEDs, for example in a resin printer
• Adjustable power supply from a 12 V or 24 V switching power supply
• Supplying devices with a lower voltage
