8.1. Power supply
The ECoSBoost 4A gets its power via a 2.1mm DC-socket, the
ECoSBoost 8A via a 4-pin Mini-DIN socket. Basically all DC or AC
transformers can be used to power the ECoSBoost, provided they
generate sufficient power. The secondary (supply) voltage corre-
sponds with the track voltage; voltage stabilising or adjustment
does not take place.
The ECoSBoost has its own internal protective circuitry for under-
voltage and overload (-current).
VIn: 14Vto19VACorDC
Input current: Max. 5A for 4A version,
Max. 10A for 8A version
•Thepeak voltageof the transformermay notexceed 20V in
open circuit operation. Otherwise the electronics of the ECoS-
Boost could be possibly destroyed.
•Please exclusively use the power supply provided with the
ECoSBoost or respectively any other power supply released by
ESU, for powering the ECoSBoost. The use of any other power
supply could lead to the destruction of the ECoSBoost. We will
not accept any warranty claims arising from the use of a diffe-
rent power supply!
8.2. Power supply unit
•Only use the power supply provided for ECoSBoost. Other
transformers may lead to reduced output or in extreme cases
to damage of the command station.
•Pleaseuse the powersupply providedwith ECoSBoostsolely
for powering ECoSBoost. Do not use it for other household
appliances.
•Check the power supply regularly for any visible damage of
the housing or the mains cable. Damaged parts may never be
used! Do not attempt to repair the power supply! Extreme
danger – risk of fatal injury!

overheating of even fire!
Depending on the version, a power supply with the following cha-
racteristics is delivered with the ECoSBoost:

VIn: 100V–240VAC,50/60Hz
Input current: 1.8A max.
VOut: Adjustablefrom15V-21VDC,stabilised
Output current: 5A max.
Plug: DC plug, 2.1mm, 1.8m wire harness

8.2.1.1. Setting the input voltage and output voltage
The power pack generates a stabilised voltage that serves to pow-
er your model train layout. The output voltage must be adjusted to
the appropriate value subject to the scale of your trains.
For this purpose there is a small, round opening at the front of
the power pack that allows you to set the voltage with the aid of
a screw driver:
Lefthandlimit: ca.14.5V
Righthandlimit: ca.21.5V
8.2.1.2. Practical voltage settings
We recommend the following settings for the different scales:
•Ngauge: 15V-16V
•H0DC(DCC): 16V-18V
•H0three-rail-system: 18V-20V
•1gauge: 18V-21V
•Ggauge: 20V-21V
