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 available 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 outputs. Generally, track voltage and accessory volt-
age are 0-18 volts (AC) each.
This Transformer is capable of operating trains up to and including dual-motored AC
locomotives. To operate at this level of track power, it may be necessary to disconnect any accessories.
You may also attempt to lower the accessory voltage settings. Refer to the "Setting the accessory
output" section on page 16.
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 Transformer will begin to flash. This indicates 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 operation while
you bring the amperage back down to a safe level.
