Thanks shipment from China the delivery times for the power supply are longer than usual, but were rather the Anfnag the displayed delivery times. The product makes a solid and safe impression. I had checked the voltage before connecting an LED Strips to study the Vorrezenzionen and was fairly close to the desired nominal voltage with 12.3V. Without problems via a small potentiometer The regulation on exactly 12V was possible. As far as I am very happy with the product just for that price
