Marklin 67020 - Z Speed controller without transformer
Z Speed controller, the controller has a speed controlled output, and also a regular output (not speed controlled).
Input max 11 volts, output max 800mA.
You would have to furnish power supply with jack plug that will fit this speed controller. The two last pictures show an example of the plug needed. This is not included.
Marklin changed the plug ever so slightly on the power packs during production, so not all wall packs will fit!
