The product name says "YI MEI DA Upgrade 48V 20A 1000W Switching Power Supply Power Adapter AC 110V/220V Driver Transformers SMPS for CCTV Radio Computer Project Led Strip Modules Light" for you to use it at 110 can or 220 volts, but as you can see on the label in the photos it only says 110 volts and there is no button on the back of the power supply to change the input voltage to 220 volts. So it's an error in the title and product images?
