The device is controlled via a rotary encoder knob and two buttons: (Switch) and (Voltage/Current).
Short press SW until the current calibration screen appears. Hook your multimeter in series (or use a high-power shunt resistor) across the output terminals to pull a steady, measurable current (ideally above 1A). Adjust the encoder until the screen matches the measured current value on your meter.

Input threshold protection (Adjustment range: 4.8V–30V, default 5.8V). Unit cuts output if input sags below this. Over-Voltage Protection
is a popular DC-DC buck-boost converter module widely used for DIY lab power supplies and battery charging. It is noted for its wide input/output range and clear digital display. iFuture Technology Key Technical Specifications Specification Input Voltage 6.0V – 36V Output Voltage 0.6V – 36V (Adjustable) Output Current 0 – 5.0A Output Power 80W (Max 100W with extra cooling) Conversion Efficiency Useful Operational Review & Tips Constant Current (CC) & Voltage (CV) Modes The device is controlled via a rotary encoder
Note: The cooling fan starts automatically when the internal temperature exceeds 50°C or the output current surpasses 1A. Interface and Button Layout
Once your targets are set, wait 6 seconds without touching any buttons, or long-press the encoder knob to save and exit back to the normal screen. 4. Advanced Settings and System Configuration Adjust the encoder until the screen matches the
When triggered, the protection will automatically turn off the output. The LCD screen will display a protection code.
For parameters like and OPH , short press the ON/OFF button to toggle the function on or off (the display will show the target value when enabled, or ---- when disabled).
