Finish Carpentry (For Pros By Pros)

...ge: AC 110V-120V / 220V-240V.Wide voltage input adjusted automatically to SMPS Model (12V 1A-5A, 12W-60W). As for Model (12V 10A-66.7A 120W-800W), there is a voltage selector switch located on one side of the switcher that is used to set the input voltage to the power supply to either 110V/120V or 220V/230V. Output current depends on the device, such as 10A 120W, 20A 240W, 30A 360W, and the max current is 66.7A, power 800W..
How to choose: The peak power is 66.7A,800W. It does not mean it can fit rate power 800W. For motor devices, the start current will be much higher than the rated power. If use resistive equipment, such as led strips, you can use higher power, such as 800W rated LEDs will also be OK. Dial to the correct gear position cut off the power before disassembling the connection..
3.Safe and Stable, Long Service Life: Switching power supply has over/under voltage, over current, overheat protection, and fan heat dissipation protection functions. Light and Portable, Easy to Operate: Net weight only 1.6Kg. Perfect choice to power led strips, car stereos, CCTV cameras, and other 12V powered systems..
How to use:The upgraded transformer has three connection methods to facilitate the use of different devices, super convenient for devices with clamp....
