Reddit reviews GALYGG 12V DC Switching Power Supply 5A 60W, Universal Regulated Transformer Converter AC 110V-220V to DC 12V, for LED Strip Lights, Radio, Computer Project

【Widely Uses】 60W 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.Thanks to the high efficiency up to 85% of this power supply, with the fanless design, the entire series is able to operate for -20 ~60 degrees. 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! 1 Year Warranty, any questions please feel free to contact us.
