The Harley Benton PowerPlant ISO-12 Pro Power Supply is a good product. Just the thing for keeping noise out of your pedal board setup.
However, beware that it comes with a wall wart style power supply with a European input plug. While the box it comes in says there are USA, Europe, UK and AU plug choices, there aren't. The other plug choices are not available, and you don't get a power plug choice when you add the product to your cart. It would be nice if the product came with a wall wart that let you use the power plug type you need, as do many other products these days, but it doesn't. If you're in the USA, UK or AU, you'll need to use a plug adapter, or buy a suitable wall wart locally.
The other thing you may need to consider is that the 12 supplied power connection cables to go from the PowerPlant to your pedals are 60 cm long. On a pedal board for 12 pedals it wouldt be useful if some of the power connection cables supplied were longer (e.g. 90 cm).
