Xenia2 Posted August 3, 2014 Share Posted August 3, 2014 I would re-checked the wiring and the design, make sure your specification is correct voltage/current. If it is that hot, not good i don't think. Link to comment
jedimasterben Posted August 3, 2014 Share Posted August 3, 2014 The LDD can definitely be warm to the touch, they dissipate on average 1-3 watts of heat. Their over-temperature protection kicks in when the internal IC hits 150°C, so I wouldn't worry about it. http://www.meanwell.com/search/LDD-H/LDD-H-spec.pdf Link to comment
speedo Posted August 3, 2014 Author Share Posted August 3, 2014 Check voltage and wiring, all look's ok. Think temperatur is around 50° (122 °F ). System consists of -2- lumia 5.2 coralux 5up LDD 250w 48v 5.2A DC Power Supply Link to comment
jedimasterben Posted August 3, 2014 Share Posted August 3, 2014 50°C is good, as long as it doesn't get much hotter than that, then you're good to go. Link to comment
