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.
