FAQ

Why does my device not work properly after connecting to AC to DC Power Supply Board? 

Please make sure that the input voltage of your device matches the output voltage. For example, 7.5V, 9V, 12V output voltage, select the voltage output that suits your device. If it still does not work, check whether the power board is connected properly and make sure that the voltage of the power board is within the range supported by the device.

Does AC to DC Power Supply Board support all types of electronic devices?

This power board is widely used in most devices that require DC power supply, such as routers, switches, 3C products, LED lights, etc. However, please confirm that the working voltage of the device matches the output voltage of the power board before use.

What is the difference between AC to DC power supply and linear power supply?

AC to DC power supply usually adopts switching power supply technology, which is more efficient and small in size, and is suitable for devices that require high efficiency. Linear power supply adjusts the output linearly, which is relatively inefficient, but its output voltage is more stable, which is suitable for applications with high power quality requirements.

My power board is overheating, what should I do?

Please make sure that the power board is in a well-ventilated environment and avoid overloading. The AC to DC power supply board has built-in temperature protection, but continuous high temperature may affect its life or performance. Check if there are any external factors causing overheating, and take necessary heat dissipation measures.

How to choose a suitable AC to DC Power Supply Board?

When selecting a power board, first confirm the required output voltage and current requirements, and match them with the output specifications of the power board. Secondly, consider the power requirements and safety protection requirements of the equipment, such as overvoltage, short circuit and overload protection.
