Waterproof AC/DC Power Adapter Supply Charger 12V 2A Power adapter with12V 1A 2A 3A US EU Plug

12V 20A switching power supply high valuea 110v 220v to dc 12v/24v power transformer for cctv system

Switching power supply, also called switch converter, is a kind of high frequency electric energy conversion device.It’s function is let a voltage through different forms of architecture into the voltage or current client demands.For example, if your home has four cameras, each camera's power is 50 w, need 12 v supply voltage, the voltage is 220 v in the home, so a power of 200 w, 12 v voltage of switching power supply can solve this problem.
