Constant Current Constant Voltage Power Supply Circuit Step Up Step Down Voltage Buck Boost Converter Solar Charger
Product Description
Innovative design of large heat sink 5A (maximum 10A) buck-boost module (constant voltage and constant current version) This buck-boost module uses a large heat sink to ensure heat dissipation; four high-power tubes, with sufficient materials; three-wire parallel-winding iron-silicon-aluminum magnetic ring inductance, not easy to saturate, further reducing heating loss, thicker 1.6 circuit Board, increased stability, input and output use high-frequency low-impedance capacitors, greatly reducing output ripple. Modular fast input and output voltage allowable range is relatively large, the output is relatively stable, and it is widely used in many fields: 1. Used to charge various batteries, constant voltage and constant current adjustable, safe and reliable; 2. Used in voltage stabilization occasions, as long as the input voltage range is within the voltage range of the voltage stabilization module, the output can be kept constant. For example, the input of a 12V battery will fluctuate in the range of 10-14V, and the output can be stable at 12V; 3. The solar panel stabilizes the voltage, the voltage of the solar panel fluctuates relatively large, this module can stabilize the output, power the device or charge the battery; 4. It can realize constant current driving of LED lights, such as battery-driven LED lights, which can allow the current to be limited to the allowable range of the LED, work long-term and reliable, and greatly extend the life of the LED.

Output current: It is generally recommended to use 5A occasions. If you need more output current, you can use two modules in parallel; monitor the heat generation during work to improve stability, and use auxiliary heat dissipation if necessary; Regarding efficiency: The output efficiency depends on the step-up and step-down working methods and the pressure difference, please pay attention; Regarding the size and weight: the design value is for reference only, there may be deviations in the measurement, please refer to the actual product.
