1.12V 50W power supply housing 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 Printer, DIY project works, LED display, LED strip light, etc.
2.This 12v 4a power source(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 functions to protect your device.
3.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.12v 4a led driver also tend to be smaller in size than linear power supplies and use less raw material making the cost of power supply more reduced.
4.Indoor use only! For long service life, please do not let the unit work long hours over rated current!
Shipments: By sea, by air, by land,or specified shipping by customer.
