On older ECoS 50000 systems, the power supply output a fixed 18 volt to the track.

b) Output socket (Low Voltage)
c) Mains socket

Supply voltage: 100V - 240 V AC, 50 / 60 Hz
Supply current: 1.8A max.
Secondary voltage: 18V DC, stabilised
Secondary current: 5A max.
Output socket: DC-socket, 2.1mm, 1.8m cable

ESU say: The power supply provides a stabilised voltage output that should only be used for your layout. For some N-gauge decoders or locos 18V may be too. We recommend a lower track voltage when using ECoS with N-gauge equipment. You may exchange the power supply (18V) against another with an output voltage of 15V free of charge. See chapter 24 of the 2nd edition manual found on the ESU website.

Newer and current versions of the ECoS 50000 and the ECoS 50200 are supplied with a power supply that allows the track voltage to be set (15V - 21V DC).

Voltage adjustment is made on the power supply unit, not on the ECoS command station.

Input voltage: 14V to 22V AC or DC
Input Current: Max 5A

• Use the supplied AC power adapter only with the ECoS. Do not use it with other household devices.
• Check the power supply regularly for damage to the case, lead and mains plug. If any part is damaged, then the power supply should not be used. Do not attempt to undertake any kind of repair to the power supply!
• Provide adequate ventilation around the power supply. If the power supply is covered, it could lead to overheating or fire!
• First connect the power cord with the correct plug, then plug in the power supply.
• Do not use a multi-plug adapters with the power supply as an overload could lead to fire and damage.

Output Voltage Adjustment
The specific output voltage of the power supply is transferred to the track. The track voltage for your specific track gauge is thus set by adjusting the output voltage of the power supply.

To achieve this, on the front of the power supply is a round hole with an adjustment dial that can be rotated with a small screwdriver.

Left stop: about 14.5 V Voltage
Right stop: about 21.5 V Voltage

Recommended voltages to be set depending on the gauge of the track:
• N-gauge: 15V - 16V
• Two rail H0 / OO (DCC): 16V - 18V
• 3-rail H0: 18V - 20V
• Gauge 1: 18V - 21V
• G Scale: 20V - 21V

The ECoS Current Monitor screen (Setup 1 tab) shows the current track voltage. Using this figure, you can precisely adjust the output voltage of the power supply.

ESU recommends the following procedure:
• Turn on your ECoS command station
• Open the Current Monitor
• Slowly turn the voltage adjustment dial until the desired voltage is displayed

Current Monitor
The current monitor will give you valuable information about the power being supplied to your layout. Using this, you can calculate the real-time power consumption of your locomotives.

• You can manage your power districts efficiently.
• The power monitor displays information for both the internal booster of the ECoS and all the connected ECoSBoost boosters.
• You can also monitor the temperature of the ECoS device.
• The Current monitor is accessible from the System Setup 1 tab. The bottom icon on the left.

a) List of all the boosters in the system
b) Name of the booster (user defined)
c) Current Power / Maximum Power Consumption
d) Bar graph display of current consumption
e) Track voltage in the booster section
f) Internal temperature of the booster

The output current monitor also shows which Booster has switched off due a short-circuit. For large layouts, this is useful for troubleshooting.
