MEAN WELL Enterprises Co., is a Taiwan based company started in 1982 with strong ties worldwide (some well-known companies re-badge their products) and they provide excellent support and backup. Meanwell is a TQM (Total Quality Management) company and is ISO9001 certified. In 2017, the 2-year return rate was 1 in 6600. Meanwell power supplies are extremely reliable in our experience with only one unit DOA (Dead On Arrival) that was replaced and three returned during the warranty period in the 10+ years we have been selling... one power supply had been installed in a control box outdoors (for advertising) and had been attacked by a nest of ants! Meanwell now offers a range of fully sealed units (IP65 and IP67 rated)... please ask us for advice for outdoor and hazardous environments. For a company video - click here.

        Some "on-the-web" comments.... "I have hundreds of 600 Watt 24V Meanwells running in the field and probably another 100+ 350Watt 5V running in the field and they are the most reliable piece of equipment compared to everything else. I've -never- replaced one in over 11 years, but I have replaced a lot of cruddy circuit boards designed or assembled by the less technically inclined (companies).", 2. "But in the end I've learnt a lesson here and that is spend the extra cash and buy some quality power supplies like the meanwell brand or else you could be in for a very frustrating time but I don't have the budget for that this year so I'll have to deal with what I have (sad face)". 3. Need a decent power supply... I can recommend mean well supplies. They are low end industrial supplies but are good quality, I use mean well in lots of equipment and have had very few failures in thousands of hours of run time.
