SHNITPWR 12V Power Supply 40A 480W Regulated Switch Power Transformer AC 110V 220V to DC 12 Volt 40amp 38A 35A 32A 30A Converter Adapter LED Driver 3 Output Ports for LED Light 3D Printer CCTV Cameras

Universal switching mode power supply. Input: AC 110V / 220V, 50 / 60Hz ; Output: DC 12V, Max 40A 480W. Three output ports. Each port outputs 0~40A automatically to match your device, 40A max in total for 3 ports. The default output voltage is 12V, but it can be regulated by 10%, from 10.8V to 13.2V. It can supply with all currents less than 40A, such as 5A, 10A, 15A, 20A, 30A, 32A, 35A, 37A, 38A, 40A. For example, if your device draws 25A, then 25A will be supplied. If draws more than 40A, only 40A will be supplied and power supply will be damaged soon. NEVER OVERLOAD ! Certified by FCC CE ROHS. We focus on producing high quality power transformers. Automatically over-current cut-off, over-voltage cut-off, over -temperature cut-off, short circuit protection. Low noise, no spontaneous combustion, no explosion, no fire hazard, stable output, safe to use. It is widely use to driving 12V LED strip light, flood light, commercial lighting project, wireless router, ADSL cats, HUB, home
