more locos can be driven at one time than the mains adapter can supply with power. With the
mains adapter #55010/NA max. 850mA, included in the start set this would be two locos averaging
400mA.
If more locos are put on the track and too much current is drawn this overloads the mains adapter
which simply switches off. This is similar to a short circuit.
Controlling more than 2 locomotives
If you want to run more than two locos are to be driven on the layout then you must
either
• connect a more powerful transformer to the PIKO Digi 1
• or connect extra mains adapters known as boosters to the model rail layout to provi-
de additional power.
N.B.: PIKO Digi 1 and PIKO Digi 2 must not be operated using mains adapters or trans-
formers of more than 45 VA capacity. Doing so can cause damage to electronic compo-
nents and the digital control could be permanently damaged.
Higher capacity transformer for the PIKO Digi 1
The PIKO T3 desk top transformer, #55005
If you have a start set with a mains adapter plug for 850 mA power (# 55010) then you
can also increase the supply to your digital layout by replacing the mains adapter with
the PIKO T3 desk top transformer, # 55005. Using this T3 desk top transformer you can
exploit the full range of the PIKO Digi 1.
N.B.: Never connect 2 mains adapters in parallel to the same PIKO Digi 1 or to the same
connection clip. This would destroy the PIKO Digi 1. Moreover, this parallel connection
can result in an exceedingly dangerous high voltage current at the plug to the domestic
power supply!
With 16 V ~ output voltage the PIKO T3 desk top transformer produces a current of 28
VA (1.75 A). This means that 4 locomotives with a power requirement of approx. 400
mA each can be run on an electrically isolated track section.
The PIKO T3 desk top transformer is connected to the PIKO Digi 1 just like the mains
adapter (see section "Connection and Operation" above). All you have to do is to fit
the connecting lead between the T3 desk top transformer and the PIKO Digi 1 (see
Operating Instructions for the T3 desk top transformer).
Additional booster
The PIKO Digi 2
To increase the power supply to a PIKO model rail layout still further i.e. in order to run
more than 2 or 4 locos simultaneously, additional power supply units (transformers)
must be connected.
