The characteristics of the switching power supply are: high-speed pass and cut-off with a circuit-controlled switch tube. The direct current is converted into high-frequency alternating current and supplied to the transformer for transformation. The wall-mounted Chinese-standard certified power adapter then generates the required set Or multiple sets of voltage! Plug-in type Chinese-standard certified power adapter and it is not very hot during operation!! The cost is very low. If the 50HZ is not changed to high frequency, the switching power supply is meaningless
Generally, plug-in power adapters are generally used below 36W. The feature of this power adapter is that it does not require AC wires, which saves costs and saves space, and does not require a countertop space for placing the power supply. It is also safer to directly plug into the plug-in board. There are a few power adapters below 36W that use desktop type. This is generally because the product is far away from the AC plug-in board or because the power adapter is large in size and heavier, or The power adapter is heavy.
