Switching Power Supply 24V 333A 800W LED Driver Regulated Transformer Adapter Converter AC110V/220V to DC24V Low Voltage Output Parameter Input: AC 100V/220V 50/60Hz; Output Voltage : DC 24V; Output Current: 33.3A; Output Power: 800W; Fix Screw Hole Diameter: 2.5mm (0.01inch); Working temperature: -20 ~50; Storage temperature: -20 ~ 85; Environmental humidity: 10-95% Great Safety The LED driver power supply is built-in safeguards to protect against over voltage, over load, overheating, and short-circuit, which will provide the ultimate protection for you and your devices. Intelligent Temp Control The AC to DC regulated Switch comes with a built-in cooling fan and a temperature detector. The cooling fan will automatically run when the inner temperature reaches 45, which makes heat dissipation more efficient and silent. Stable Output The voltage transformer is a built-in advanced synchronous rectifier smart chip and EMI filter, converting AC voltage to stable DC voltage, effectively reducing electromagnetic interference. Application Great for LED Strips, 3D Printers, CCTV cameras, wireless routers, HUB, and Indoor use only! Warning! 1. 110V/220V must be selected by switch before use to avoid damage. Please change the switch to 110V for USA/CA and 220V for EUR(Remove the metal back cover where the 110V/220V yellow sign). 2. When working at 110V, please keep the load under 70%; When working at 220V, the load can reach 100%. _x000D_
