Product Description

400W 12V 33.3A Switching Power Supply AC to DC LED Driver

 

Feature:
 

Widely Uses: 12V 33.3A 400W 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 AC180~264V 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 85%-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.

Package included:

1 x Power Supply (Power cord is NOT included.)
Please note: The power cord is not included in the package of this product. All of our products are covered by a one-year warranty.

Cautions:

1. The actual power is 80% of the rated power of the power supply (example: If the power of your device is 400watts, you need to buy a power supply of 500 watts or more).

2. In order to avoid interference from filtering, the power supply and the equipment need to maintain a distance of more than 3m.

3. Please do not use any equipment overload to avoid damage to the equipment.

4. Need to consider the operating environment temperature of the switching power supply, and the presence of additional auxiliary cooling equipment, in too high a ring temperature switching power supply need to reduce the amount of output. (If the power of your equipment is 400 watts, you need to buy a power supply of 500 watts or more). Indoor outdoor use, the power supply is waterproof Power supply built-in intelligent cooling fan, working with slight sound, this is a normal phenomenon.
