Property me the power mains plug appointed to replace a power supply Gardena since the Gardenanetzteil was too big for my distribution box. The power supply instead of the specified 24 V idle 30V with load 29.6 V. However, the Gardenaventile can be controlled without problems. I use the same power supply to power Verso narrowing of Raspberry Pi that controls the valves. My inserted voltage converter with 30 V at the upper limit and runs just like that. Deshalt 2 star deduction for the high deviation from the nominal voltage. The Gardenanetzteil provides incidentally no 24V 26V but under load. If you can live with just 30V receives a plug power supply with good price / performance ratio.
