Have a transformer for 12V halogen ceiling recessed luminaires needed because the old to 15 years gave up the ghost. Attached are 4 x 25 W halogen spotlight and 2 x 5W LED spotlight, operated by electronic touch dimmer (trailing edge dimmer. Item arrived quickly and well packaged to. The transformer is well made, no cheap plastic. Is already evident at the terminals, where the screw a metal plate homogenously pressed onto the wire and not even compresses the screw the cable at one point. Text of the description is only in English, but the sketches and the imprint on the transformer are clear. At 230V input side are 2 Engangsklemmen (and 2 output terminals for looping through the supply voltage for any other consumers). On the 12V side, a total of 3 terminal pairs for connecting the lamps, which can be used. I have put all the lights on an exit because bereits.ein distributor in the hollow ceiling was with only one exit. The rounded ends of the transformer, he read well through the lamp opening slide behind the sheetrock.
Plugged in, turned on and working, no humming noises have found even during dimming. For life, of course, no statement can be made now.
