Can a Keyboard controller be powered from a DC din connector?
QKB15S Keyboard Controllers are powered by +12 VDC usually from a wall transformer. The Q101, Q103, and Q137 Power modules provide DC power via a 6 pin female connector. The voltages available are +15VDC, -15VDC, and +5VDC – all well regulated. The keyboard controller has it’s own internal regulator and only needs about 9VDC – 18VDC at less than 50ma. So you can provide power to the keyboard by a short cable from one of the modules. When you turn your system off, the keyboard will also go off. When making such a cable, double check the pin outs! The connector on the keyboard is a 2.5mm ‘DC Power’ connector with the center pin being +. For details on pinouts, see the Technical Information Page.
