adjustment method: (using tools multimeter, a screwdriver)Voltage adjustment: according to their own required voltage rotating power board “CV” blue potentiometer, clockwise voltage up, counterclockwise down the output voltage. The maximum output voltage is about 20% lower than the input voltageOutput current adjustment: multimeter or ammeter to 50A20A or 10A current gear, the power supply voltage to 5V, constant current potentiometer “CC” counterclockwise about 10 turns, the current is adjusted to the minimum with a multimeter short-circuit output, and then clockwise adjustment of “CC “potentiometer to adjust the current to the required current value, (Note: constant current potentiometer “CC” counterclockwise turn 10 turns, the power supply may not have an output voltage, this is because the current is adjusted to 0 A.) Don't worry about it, adjust the current clockwise and there will be output.)Package include:High-power step-down power supply * 1 (style of your choice)
