PZS-3 English
Power supply
The module has to be supplied via a transformer not in use as driving
transformer. Note: Driving transformers providing an additional output
for further accessories are not suitable to supply both rails and module,
as they internally contain only one transformer. Note: It is possible to
supply the module via a transformer used to supply other accessories
as the rails (e.g. lighting).
When connecting the module to a transformer in use as driving
transformer, short circuits occur within the PZS-3 which may damage it
irreparably.
The seperate supply of module and rails has the advantage that the
driving voltage can be set individually. E.g. the maximum driving
voltage for the shuttle-train traffic (and the maximum speed with full
speed) can be (pre-) set individually.
