Most DCC sets do NOT include the transformer or power supply necessary to operate it. WHY? Because they are sold throughout the world and power mains vary in voltage and frequency.

At Litchfield Station we stock units designed for 115 volt 60 hertz power mains, such as are found in North America.

What is the difference between a TRANSFORMER and a POWER SUPPLY?

A transformer,
as its name implies, transforms one AC voltage into another. The output is still Alternating Current (AC) at the same frequency as the input. In the DCC world, this transformation is from a line voltage (115) to the voltage needed by the set (usually 15 to 18).

A power supply
actually converts AC voltage to a lower voltage DC. These units are sometimes "universal" units that can can take an input from 110 to 240 volts AC at either 50 or 60 Hz, covering most power grids in the world. The output is sometimes fixed at a single value or adjustable via a switch, or similar. Many of these are regulated, in that the output voltage remains constant for current draws over a (specified) wide range. Those that are not regulated will sag, that is, the voltage will drop as the current draw increases.
