Hello,

I have few projects in mind which will use WS2812b (5v) or WS2815 (12v) LED strips. However, these strips have very high current requirements e.g. 1 meter 60LED/m WS2812b strip can use around 3.6 amp (60mA/led * 60).

I'll really appreciate pointers to good quality wall adaptors in 5v or 12 volt variety which can deliver >= 5 amp and

Won't get me in trouble with insurance companies
Can be used safely around 3 year old (should not have naked connectors etc).

Thanks for your help.

I think you'll struggle to find wall adapters with such a high current rating. You'll most likely have to use a "standard" power supply with mains cable input & low voltage output terminals.

If it's in an appropriate case with no finger access whilst also providing ventilation, then you won't have any issues with insurance or kids.

I haven't purchased anything recently, but computer power supplies are great for this kind of thing. They have 12v and 5v available with decent current capacity, and they're a dime a dozen for older units which still work fine.

Jaycar or trademe would have dedicated power supplies too. You just have to pick the right one which suits you. Jaycar usually aren't very competitive with their pricing though..
