Consists of a locomotive decoder, a 5-pole high-efficiency motor, and hardware for converting specific older Märklin H0 locomotives with the smaller size flat commutator motor to digital high-efficiency propulsion.
The electronic circuit has 4 controllable functions (headlights from the "function" button, smoke generator and Telex couplers, for example, from "f1" and "f2", minimal setting for the acceleration and braking delay from "f4"). The Control Unit (item no. 6021) must be used as the central unit to control functions "f1", "f2", and "f4".
Adjustable maximum speed. Adjustable acceleration and braking delay. 80 digital addresses can be set. The functions "function" and "f1" are turned on in conventional operation with AC power.

Information About This Product:

We differentiate roughly 2 different types of motors among the uni-versal current motors used with Märklin H0: the newer drum-style commutator motor and the flat commutator motor that used to be the standard motor. The easiest way to tell the two types of motors apart is the type of brushes they use.

Drum-style commutator motors have 2 carbon brushes, while the flat commutator motors have a carbon and a copper mesh brush (spare part number 600300). The familiar 60901 conversion kit can be used for drum-style commutator motors.

With the flat commutator motor, there are a number of variations due to different armature diameters and brush plates. The 60903 conversion kit can therefore only be used with certain models.

The manufacturer warranty is covered only when the 60903 high-efficiency propulsion set is installed by an authorized Märklin dealer.
