Powering your layout with the CW-80 Transformer
Y
our CW-80 Transformer provides a total output of five amps. The track outputs will deliver
all of this power to the track when no accessories are connected to the Transformer. Keep
in mind that connected accessories borrow some of this power. For example, if the accessories
require two amps of the total five-amp capacity of the Transformer, you have three amps avail-
able for track power. This built-in flexibility will provide power for virtually any small- to
medium-sized railroad. Also, available voltage depends on how much load is on the two out-
puts. Generally, track voltage and accessory voltage are 0-16 volts (AC) each.
This Transformer is capable of operating trains up to and including dual-motored AC
engines. To operate at this level of track power, it may be necessary to disconnect any acces-
sories. You may also want to attempt to lower the accessory voltage settings. Refer to the
“Setting the accessory output” section.
You may momentarily approach or exceed the five-amp limit of the CW-80 Transformer
when pulling illuminated cars, fighting over grades with heavy loads, or operating accessories.
When you reach five amps, the green light on the Controller will begin to flicker. This indi-
cates that the Transformer is in “fold-back mode.” In fold-back mode, the Transformer is
automatically reducing, or folding back, power. This gradual reduction in power provides
interruption-free power while bringing the amperage back down to a safe level.
