10% of the calculated sum of power consumption The Booster B-3 can provide 2,5 A current. If your overall power demand exceeds the capacity of one booster you have to connect additional boosters according to the special requirements of your layout.
Any other use is inappropriate and invalidates any guarantees. The booster B-3 should not be mounted by children under the age of Reading, understanding and following the instructions in this manual are mandatory for the user.

Track voltage Operation display (LED) Ports The booster B-3 can be connected either to a port for a Märklin- compatible booster or to a DCC-conforming booster port. Advice: The port ( Märklin-compatible or DCC-conform) used for the booster´s connection to the control unit, is of no importance for the data format used to control the decoders.

The DCC-input of the B-3 is isolated through an opto-coupler. Balanced track voltage The booster B-3 provides a regulated track voltage, which can be set to a value of 12, 15 or 19 V. At delivery the track voltage is set to 19 V.

English Booster B-3 Short-circuit protection The Booster B-3 provides an intergrated short circuit breaking in shape of an integrated current limitation. This causes the booster to switch off automatically when a short circuit occurs at the track output and thus prevents damages to the booster, the tracks and the vehicles.
Booster B-3 English 5. Splitting your model railway layout Split your model railway layout in several track sections electrically isolating them from each other. Every section has to be supplied by a booster of its’ own. In each section a maximum of three to five locomotives should run at the same time.
MasterControl has to be set to "short circuit polarity: positive (MM)" (= factory setting). The booster B-3 has two Märklin-booster ports and two DCC-booster ports to be used at choice. Please make sure that the pin assignment of the central unit´s booster interface corresponds to that of the booster...

English Booster B-3 Connecting the tracks Connect the booster´s track port to both rails (with 2-rail systems) or to one rail and the middle conductor (with 3-rail systems). These connections should be repeated every 2-3 meters, because the resistance at the connection points of the tracks is quite high. When choosing too high intervals, problems with the short circuit indication or the power supply of the vehicles may occur.
