9V and USB power converters for Eurorack

  • Hi there, how much power 12V Eurorack to 9V Power Converter gives? I need at least 150mA.
    Is there any manual how to solder cables?

    1. I’m not an electrical expert and I’m using ready made PCBs. The output current is depending on the input current which is fed into the converter.
      Output Current:3A (max),actual testing input 12V output 1.5A. There are only two cables to solder on the input pins of your device. The flat-wire which connects to the Eurorack power rail is already pre-soldered.
