10 PCS AC-DC Switching Power Supply Module [12V] [500mA]

Description:
A switching power supply takes an AC input, but rectifies and filters into DC first, is converted back into AC at some high switching frequency, steps down the voltage with a transformer, then is rectified and filtered into a DC output.
Switching AC-DC converters utilize a switching regulator to control the conversion of electrical power in the most efficient way possible.
While there are two main types of regulated power supplies (Switching and Linear), switching AC to DC power supplies are comparatively more reliable and efficient than linear AC to DC converters.
The main advantage of the switching power supply is greater efficiency than linear regulators because the switching transistor dissipates little power when acting as a switch.
Other advantages include smaller size, lower noise, and lighter weight from the elimination of heavy line-frequency transformers, and comparable heat generation. Standby power loss is often much less than transformers. The transformer in a switching power supply is also smaller than a traditional line frequency (50 Hz or 60 Hz depending on region) transformer, and therefore requires smaller amounts of expensive raw materials, like copper.
