2.3 Power Supply for the Z21 Digital Centre

As a power supply for the Z21 Digital Centre, please use exclusively the supplied AC adaptor (Art. No.
10851). Positively do not use a wound-core transformer!
With the Z21 Digital System, you can modify the voltage applied to your system at any time by soft-
ware. For this purpose, change to the menu "Z21 Settings" in the Z21 mobile app. Always make sure
to stay in 11 to 23 V range. Typical voltage ranges are from 14 to 18 V (for the gauges H0 and TT) and
approx. 12 V (for the gauge N).
Maximum input voltage for the Z21 Digital System is 24 V. The maximum track voltage is always 1 V
below the input voltage.
The Z21 Digital Centre is designed for loads of up to 3.2 A. If frequent power cuts occur in the system
due to overloads, please install a booster (see Page 46).
Note: To fi nd out the current power consumption of your system, check the menu point "Power
Centre" in the "Z21 Settings" menu of the Z21 mobile app.
