Zoom
Description
Brand: Valefod
Model: VA-139-52
Features:
- DC to DC step-down module
- Thickened circuit boards
- Advanced solid-state capacitor
- Short circuit and over-temperature protection
- 100% tested, sealed in anti-static packaging
Kindly Note:
1. Input voltage must be 1.5 V higher than the output voltage, no boost
2. Do not reverse the input and output interface
3. Keep output under 2.5A (or 10W) and use a heat sink when for a long time working
4. The factory settings stay a high voltage, you may need to contrarotate the screw on blue potentiometer about 7-15 circles before the output voltage changes

Package List:
10x DC to DC Buck Converter Module
• 【High Precision】The buck converter consists of 36u thickened circuit boards, high-Q inductance with output LED indicator, and superior solid-state capacitors that can effectively filter out high frequency noise. Suitable for various electronic projects.
• 【Input Voltage】DC 3.2V to 35V (input voltage must be 1.5V higher than the output voltage, no boost).
• 【Output Voltage】DC 1.25V to 30V voltage is continuously adjustable, maximum output current is 3A.
• 【Mini Size】45 * 23 * 14 mm (with potentiometer). 10pcs included.
• 【Easy to DIY】Connect to power source, using a mini screwdriver to increase or decrease output voltage by adjusting the screw on the blue potentiometer and monitor voltage with multimeter to get the needed voltage, clockwise to step up voltage and counterclockwise to step-down voltage. (Factory default stays a high voltage, you need to contrarotate about 7-15 circles before the voltage starts ramping down, 1 circle means +/- 1V)
