GALYGG 12V 3A Power Supply, 36W LED Driver Universal Regulated Transformer Adapter AC 110V-220V to DC 12V Low Voltage Output for LED Light, Radio, Computer Project

Key features

• 【Widely Uses】12V 3A 36W ac-dc power supply housed in a compact metal case. This rugged unit is ideal for reducing standby power usage in an abundant number of applications, more than a linear supply, such as industrial automation, 3D Print, DIY project works, LED display, LED strip light, etc.
• 【Safety Performance】This Switching Power Supply(SMPS) operates from AC110V~220V and converts to DC 12V. Built in fuse providing a voltage regulated single output which can be adjusted with an on board potentiometer. With short circuit, overload, over voltage, protection function to protect your device.
• 【High Efficient】Linear power supplies have efficiencies in the 40%-60% range, while switching power supplies fall in the 70%-90% range.A highly efficient and reliable dual output enclosed power supply, with a high operating temperature of -20~+60°C and cooling by free air convection.
• 【Energy Saving】Uses a switching regulator to convert AC mains power to low voltage DC and it does this much more efficient than a linear power supply.Switching power supplies also tend to be smaller in size than linear power supplies and use less raw material making the cost of power supply more reduced.
• 【Notes】Indoor use only! For long service life, please do not let the unit work long hours over rated current. Any questions please feel free to contact us.
