The 12V DC power supply is one of the most commonly used power sources today.  These are switch mode power supplies which means the output is regulated to 12V.

Generally, the 12VDC output is obtained from 110VAC or 220VAC inputs using a combination of transformers, diodes and transistors. Most LCD screens, hard drives, audio devices and other device needs them to work together. For example, the 12VDC led power adapter and 12v 150w waterproof led power supply can be applied in a lot of scenarios.

Also, the constant voltage led lights requires 12VDC power supply. Constant voltage led driver 12v 250w can be matched with 12vdc 200w LEDs. The most common are the dimming CV and non dimming CV power supply. For north American, 110VAC and 277VAC is suitable. Smarts UL appoval led power supply offer 100-277VAC and 12V 24v dc. As for European countries, most of them got CE/rohs certificates with quality assurance.
