1PC 12V 10A 120W Power Supply Adapter, Universal Regulated Switching Transformer AC 110V/220V to DC 12V 10A Converter LED Driver for LED Strip Light, Security System

12V 10A 120W AC-DC power supply housed in a compact metal housing. This robust unit is ideal for reducing power consumption in standby mode in a large number of applications, more than linear power, such as industrial automation, 3D printing, DIY projects, LED display, LED strip light, etc. This switching power supply works from AC110V ~ 220V and converts to DC 12V. Built-in fuse provides a single voltage regulated output that can be adjusted with a built-in potentiometer. With short circuit, overload, over voltage, protection function to protect your device. Linear power supplies have yields in the range of 40-60%, while switching power supplies are in the range of 70-90%. A highly efficient and reliable dual output enclosed power supply, with high operating temperature of -20~+60℃ and free air convection cooling. Uses switching regulator to convert mains power to low voltage DC power and this is much more efficient than linear power supply. Switching power supplies also tend to be smaller than linear feeds, and use fewer raw materials. Indoor use only! For a long service life, please do not let the device work long hours above the rated current!
