9-14V wide voltage input, support DC 1.2-5.6V precise voltage regulation, matchbox size but can continuously output 20A strong current! Reserve fixed voltage and infinitely adjustable shorting port, easy to drive the car LED lights, car recorder, refrigerator and other equipment, is the ideal power solution for automotive electronics modification and electronic DIY.

Key Features:

- Product Name: High Power DC Buck Module
- Input Voltage: DC 9-14V
- Output Voltage:
  - DC 5V, Fixed Selection
  - DC 1.2-5.6V, Support Infinitely Adjustable
- Maximum Output Current: 20A

Voltage regulation mode:

- Mode 1: Fixed voltage regulation: Solder the corresponding shorting point to get the fixed output voltage (corresponding to 5V output module)
- Mode 2: Inferential voltage regulation: Solder the shorting point of “Inferential Voltage Regulation” to enable the Inferential Voltage Regulation Mode, and then gently twist the potentiometer to adjust the voltage in the range of DC 1.2-5.6V (corresponding to the Inferential Adjustable Module). (corresponding to the induction adjustable module)
  Note: You can’t weld more than one short contact at the same time! Otherwise the module may be burnt!
