Ideal for DAC’s and Phono preamplifiers that carry external switched power type mobile charger. The output is 5Vdc and another output can be set (12Vdc, 15Vdc, etc.) Optionally you can put two outputs with different connections in the same box. In the photos has a 5Vdc output with USB output connection.”
