Compact 12V DC power supply with super value for money.

The power supply unit makes a good impression, have a built from previous delivery. It provides 9 LED above the kitchen worktop and working properly. The newly ordered power supplies should provide lights in the dressing room and in the living room closet each 3 LED.
Both power supplies have been delivered faulty, both power supplies deliver no voltage! When a power supply the wiring diagram was glued upside, so at 230 V Anschuss 12 V, and in the 12V terminals 230V!
This is a NO GO, so it does not go!
