1x DC Buck Converter 

  • Non-isolated step-down/buck module, the input voltage should be higher than output (continuously adjustable) at least 1.25V.
  • With over-voltage/over-current/over-temperature/input reverse connection protection.
  • Three high frequency low impedance electrolytic capacitors makes the output ripple to the minimum.
  • Has fixing hole for fan installation, fuse and power output indicator, can be converted to single-turn potentiometer with handle, ultra-stable performance.
  • Multiple application such as car LED power supply/small power motor speed control/power supply transformers, etc.
