Assembly of the electrolytic capacitors C1 and C2:

The connection wires of capacitor C1 and C2 have to be bent by 90° before

assembly. The capacitors have to be soldered so that they are laying flat above the

components of the pc-board. The capacitors have to have a distance of 5mm. A

contact between the capacitors has to be prevented.

DigitalBooster DB-2

from the Digital-Professional-Series !

DB-2-B Part-No.: 080061

>> kit <<

The DigitalBooster DB-2 is a short-circuit-proofed power

amplifier (booster) for digital model railway layouts.

Maximal power output: 2.5A.

The DB-2 amplifies the data formats Märklin-Motorola, mfx®,

M4 and DCC

The DB-2 can be directly operated on several digital

command stations by use of the attached 5-poles booster-

bus cable:

⇒ Control Unit (6021)

⇒ Central Station 1 and 2 (CS1 and CS2)

⇒ Intellibox, EasyControl, ECoS, DiCoStation, KeyCommander

⇒ TWIN-CENTER

This product is not a toy! Not suitable for children under 14 years of age! The kit contains small parts, which

should be kept away from children under 3! Improper use will imply danger of injuring due to sharp edges and

tips! Please store this instruction carefully.

To enable the DigitalBooster DB-2 to supply the maximal possible digital current it has to get a minimum of 52VA from a model railway transformer at clamp KL1. The transformer output voltage can be between 16 and 18 Volt AC. Littfinski DatenTechnik (LDT) Operating Instruction If the transformer supplies already other consumers on the layout you have to take special attention to the correct terminal occupation at the supply clamp KL1.
