The transformer is built very flat and fit easily with me through my 75mm holes in the panel ceiling. He has a very low delay, is barely warm during operation and works without humming or buzzing. A star I must however deduct, as the 30W-Travo at a placement through my LEDs already starting at only 21 Watts (measured power) no longer worked (protective stop so that the LEDs only blinked). By design draw some LED bulbs when you turn more power than during operation. This applies to my bulbs probably particularly. This Travo tolleriert this increased inrush even momentarily and reacts immediately by switching off (the LED will flash). I expect that this protection circuit reacts more slowly because for a fraction of a second could also be a 30W transformer without prejudice to deliver a significantly higher performance.
