The output voltage can be adjusted arbitrarily: The Adjustable USB Step Up Down Power Supply Module used as a USB input adjustable desktop power supply, the output voltage can be adjusted arbitrarily, and the current limit is 0-2A (wide input 4-13V, wide output 0.5-30V arbitrarily adjusted, with short circuit protection, the short circuit does not burn)
Used as a USB charging cable, the charging voltage and maximum charging current can be adjusted arbitrarily (any voltage, with constant current, anti-backflow, which can meet the charging of most batteries)
Three input power modes: Input 1: Standard Type A USB Male. It just can input DC 5V. Input 2: Micro-USB Female. It just can input DC 5V. Input 3: IN+ and IN- welding pads. It can input DC 4.0V-13.0V. When using the welding pad to input, be careful not to connect the reversed positive and negative poles, and do not connect to AC power
Multiple protection functions: short-circuit, over-current, over-temperature, over-power, over-voltage protection, charging anti-backflow protection
Wide application: It is widely used in ordinary power supply, battery charger, LED driving power, instrument voltage display, test counter, circuit test, power conversion.
