    Outdoor/Weatherproof CL2 power supply??

    Anyone have a recommendation for a line voltage powered power supply with the following characteristics-

    120VAC input (hardwired, Not cord and plug)
    12 or 24VDC output (load is less than 1A)
    Class 2 or 3 output
    NRTL listing
    Rated for -20C to 60C or greater
    Weatherproof enclosure

    Everything I find is RU, but I don’t need a full 508a panel, just a power supply for a UL listed relay and put the two together in separate enclosures (outdoors) or the same, either way.

    I don't understand. If you are going to put a relay (obviously not outdoor/weatherproof) in a weatherproof enclosure why does the power supply need to be weatherproof if you can put it in the same enclosure?

    Fair question. The power supply doesn’t need to be weatherproof per se but, does need to be rated for high/low temps. The relay is listed for extended temp operation. I will use a a NEMA 4X enclosure to house it.

    I have found plenty of power supplies that fit this description except they are not UL listed (only 508a, I’m not building an industrial panel, it’s a building control/automation application)

    I think your bigger problem is finding something that will withstand 140 deg F or greater. Putting it in an enclosure and you might as well be putting it in an oven. Why can't this setup be located in a location with more reasonable temperatures?

    And +60c. I stand corrected. It's also UL listed.

    It’s an island essentially. A gas grill 100’ from a building with a single 120v feed. They want control of it. (How is via a 120v gas solenoid-done by plumber, they don’t make a low voltage version. We have to use a programmable power limited controller. Can’t get anything inside
