2. Safety Information and Precautions

• This is a DC power module. Do not connect it to AC power under any circumstances.
• Ensure that the input power supply capacity is greater than the load power requirement to prevent instability or damage.
• If the module becomes hot during operation, reduce the output power to prevent overheating. Consider adding a cooling fan for sustained operation above 30W.
• Always read this user manual and product description thoroughly before use.
• When using the module for battery charging, connect the input power before connecting the battery. Ensure the output voltage is set higher than the battery voltage.
• This product does not have output reverse connection protection for the battery. Reversing the positive and negative terminals of the battery will damage the device.
• Battery charging requires specific electrical knowledge. Non-professionals should not attempt direct battery charging to prevent fire and explosion hazards.
