- Variable AC Output: Provides 0-18 volts AC for controlling train speed and power.
- Accessory Operation: Includes programmable AC output specifically for powering accessories.
- Versatile Use: Ideal for train sets and small to medium-sized layouts.
2. Setup
2.1 Safety Precautions
- Always ensure the transformer is unplugged from the wall outlet before making any connections.
- Place the transformer on a stable, dry surface, away from water or excessive heat.
- Do not overload the transformer. The CW-80 is rated for 80 watts.
- Ensure all wiring is secure and free from frayed insulation to prevent short circuits.
2.2 Connecting to Track
Locate the "TRACK" terminals on the back of the CW-80 transformer. These are typically marked 'A' and 'U'.
- Connect one wire from the 'A' terminal to the center rail of your model train track.
- Connect another wire from the 'U' terminal to the outside rail of your model train track.
- Ensure connections are tight and secure to prevent intermittent power supply.
2.3 Connecting Accessories
The CW-80 transformer includes dedicated terminals for accessories, typically marked "ACCESSORY" and 'U'.
- Connect one wire from the "ACCESSORY" terminal to your desired accessory (e.g., lights, switches).
- Connect another wire from the 'U' terminal to the other connection point of your accessory.
- Refer to your accessory's instruction manual for specific wiring requirements.

3. Operating Instructions
3.1 Powering On
Once all connections are made, plug the transformer's power cord into a standard wall outlet. The green indicator light on the transformer should illuminate, indicating power is supplied to the unit.
3.2 Controlling Train Speed and Direction
The CW-80 features an engineer handle for controlling train operations.
- Speed Control: Slowly raise the engineer handle to increase the voltage to the track, thereby increasing the train's speed. Lower the handle to decrease speed.
- Direction Control: To change the direction of the train, quickly lower the engineer handle all the way down and then raise it again. This rapid cycle of power interruption and restoration signals the locomotive to reverse direction. Repeat this action to cycle through forward, neutral, and reverse.
3.3 Operating Accessories
The accessory output provides a constant or programmable AC voltage for operating various layout accessories. Consult your accessory's manual for its specific power requirements and how to connect it to the CW-80's accessory terminals.

4. Maintenance
Proper maintenance ensures the longevity and optimal performance of your CW-80 transformer.
- Cleaning: Periodically wipe the exterior of the transformer with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure the unit is unplugged before cleaning.
- Storage: When not in use, store the transformer in a cool, dry place, away from direct sunlight and extreme temperatures.
- Connection Checks: Regularly inspect all wire connections to the track and accessories for tightness and signs of wear. Loose connections can cause erratic operation or short circuits.
