I have only been using the 350 volt 12 volt Ray WU power supplies but I just plugged in 2 of the 4 supplies and they keep blowing the house fuses, so they are obviously faulty. I have been reading that Meanwell seem to be a better quality supply even though they are more expensive. I have been on their website and I'm a bit confused about all the different types that they have. Can someone recommend which ones I should get and is there an Australian supplier that you recommend?
