I have been using some sealed units of Chinese origin bought on eBay. Like this one:
https://www.ebay.co.uk/itm/165145242820I've have a couple fail on me. They aren't being used at anything like their "notional" rated current (more like 3 or 4A maximum).
So I'm looking for recommendations of a suitable replacement. It is used outdoors (but inside a box) so the "waterproof" bit is relevant though condensation is the problem not immersion.
Thanks
