AC to DC converter: Input AC 110V/220V, Output 12V, Rated power 100A 1200W, PSU(SMPS) convert AC to DC, output current depends on the requirements of the power consuming equipment, Power multiple devices with different Currents/ Watts Intelligent Cooling: 12V 1200W power converter with aluminum alloy shell, built-in cooling fan, more efficient cooling, more stable work, high efficiency ???USED WIDELY???DC 12V Power Supply Used for industrial automation equipment, radio,Amplifier,Radios,LED drive, CCTV Camera System, 3D Printer, Car Stereos, water Pump and more 12V Device. NOTE:Not suitable for charging Battery,Speed Control Motors. Safe stable: long service life, power supply with over/under voltage, overheating protection,Compact:24.5 x 12.5 x 6.5 cm/9.6 x 4.9 x 2.5 inch, weight 1.6 kg Note: SMPS peak power is 100A 1200W, avoid overload, For resistive equipment, Recommended for equipment under 80A 960W. For motor equipment, the starting current will be much higher than the rated power and the peak power of the SMPS needs to exceed 2 times the motor power.
