- Three input power modes: Input 1 is Standard USB Type A male (DC 5V). Input 2 is Micro USB female (DC 5V). Input 3 uses IN+ and IN- pads for external DC input (DC 4.0–13.0V). When using the pads, ensure correct polarity and do not connect AC power. - Adjustable output with safe operation: Output voltage 0.5–30V with a maximum current of 2A. Wide input 4–13V. Includes short-circuit protection; a short circuit will not cause burning. - Safe USB charging capability: When used as a USB charging supply, charging voltage and maximum charging current can be set arbitrarily. Supports any voltage, constant current, and anti-backflow to meet the charging needs of most batteries. - Comprehensive protection: Short-circuit, over-current, over-heat, over-power, over-voltage protection, and charging anti-backflow protection. - Practical use scenarios: - Use as a configurable bench power supply for electronics prototyping, powering development boards and sensors from 0.5–30V up to 2A. - Charge various batteries with CC/CV charging and anti-backflow protection, suitable for many battery types. - Power USB-powered projects or devices from USB or external DC input, giving flexible voltage options for testing and development.
