💡 YI MEI DA 48V 20A 1000W Switching Power Supply for CCTV, Radio, Computer Project Led Strip Modules Light - Upgrade Power Adapter Driver Transformers, AC SMPS 110v/220v Review

If you are using this item at home and want insurance if it lights up this will not work. BUT, if you live in a concrete box like me, UL listing doesn't matter. Works as expected for LED installations, 5 stars.

If you need a power supply, then take it I had no problems starting a 1000w car audio amplifier from this power supply, it heats up a bit but holds up well. The only downside to using a car audio amplifier this way is that the lights in the house are pretty dim.

Used with pre-wired cable line with power switch and from there to car audio amplifier to power a pair of 500w subwoofer for home theater system and it also works great. has a built-in fuse for security.

product name says "YI MEI DA Upgrade Switching Power Supply 48V 20A 1000W Power Adapter 110V/220V AC Driver Transformers SMPS for CCTV Radio Computer Project Led Strip Modules Light" so you can get it at 110 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?
