High-power DC power supply module with strong load capacity, suitable for high-power-consumption devices5. Compact design for easy installation and excellent heat dissipation, ensuring stable operation over extended periodsProduct Specifications:Input Voltage: 6–80 V (must be at least 5% higher than the output voltage)Output Voltage: Fixed at 3.3 V, 5 V, or 12 V (user-selectable)Output Current: 1.2 AMaximum Peak Current: 1.5 AEfficiency: >90%Precautions:1. The input voltage must be higher than the output voltage; ideally, maintain a voltage difference of at least 2V. Do not reverse the polarity, as doing so will burn out the board.2. It is recommended to disconnect the power supply when wiring; otherwise, sparks may occur at high voltages, posing a risk of damaging the chip.3. Ensure proper protection for inductive loads to prevent excessive back-EMF from exceeding the chip’s tolerance range.4. The higher the power drawn by the module and the closer the current is to the maximum current rating, the greater the heat generation. Ensure adequate heat dissipation during use.5. Without external cooling, continuous current should be kept below 1A. If the current exceeds 1A, additional cooling is required; otherwise, the output will trigger thermal shutdown.6. The operating voltage should be kept below 76V. If the supply voltage is unstable, voltage spikes exceeding 80V will trigger the chip’s internal overvoltage protection. To ensure stable operation, allow for an appropriate margin.Package Contents:Module × 1
