LED transformer 50W, transformer, driver, Driver, DC 12V Model 4260393030206

I've tried the transformer and for testing purposes charged him with 20W. At this low load the transformer already achieved an efficiency of over 86%, if I have not miscalculated. Normally, switching power supplies achieve at low load is not their full efficiency, therefore this value is more than I expected.

The quiescent current consumption without load is less than 0.2W and is thus very good.

Exposure to the full 50W I have not done but I expect at good values ​​actually no nasty surprises.
I must add that I also the next larger model with 60W own model: 4260393030213, which is obviously technically different at all from this 50W model. All components and serial numbers appear to be equal to a hair. But I recommend because of the guarantee no experiments with> 50W perform. One should keep reserves at the PSU anyway, therefore a continuous operation with the full 50W in this case should represent no problem.
