The input voltage of this module can be adjusted between 4V and 35V, making it flexible in many different application environments. 2. High-precision output voltage: to ensure the stable output of current and voltage, no matter how the power supply conditions change, it can remain stable, making the power supply more reliable. 3. Effective linear regulation: Through the internal regulation circuit, accurate current and voltage control can be achieved, with excellent linear regulation and load regulation performance. 4. Built-in short circuit protection and overheat protection function: When the module encounters a short circuit or overload, it can automatically cut off the power output to prevent the equipment from being damaged. 5. Small and light, easy to integrate: The module is small in size and light in weight, and can be easily integrated with devices without taking up too much space. Specifications: New and high quality! Material: PCB board+Electronic components Color: As the pictures show Size:4.94*3.74cm Module Type: Non-isolated step-down constant current/constant voltage module (CCCV) charging module Input Voltage: 4-35V (Note: Minimum 7V is required for constant current input) Output Voltage: 1.25-25V continuously adjustable, default shipping voltage 4.2A, current 1A Output Current: 12V to 5V 2A (Constant current range: 0.2A-2A adjustable) Light Switching Current: Fixed at 1/10 of the adjusted constant current value Output Power: 10W with natural cooling, 15W requires heatsink installation Conversion Efficiency: 80% (Higher output voltage results in higher efficiency) Operating Temperature: Industrial grade (-40℃ to +85℃) (If ambient temperature exceeds 40℃, reduce power or improve cooling) Full Load Temperature Rise: 45°C Indicator lights: Red for constant current, red for charging, blue for charging complete.
