Cytron DCC Power Amp
The Cytron Power Amp takes the logic level DCC signal from the Protothrottle Receiver and produces full voltage DCC. The Cytron will handle up to 13A of power, more than twice what any large scale decoder on the market needs.
The image below shows the minimum components required for deadrail DCC operation. To the left is the Receiver. The yellow, black and white wire is the logic level DCC signal from the receiver to the Cytron in the middle. The component on the right is a 5v ‘buck’ down voltage converter. These convert whatever battery voltage you have down to a nice clean 5v power for the receiver. The two green screw terminals on the botton of the Cytron are the DCC outputs. Connect these to the ‘track power’ inputs on a DCC decoder. Click on the image below for a full size picture for better detail.
The below image shows a track power configuration. Basically the same hookup but we drive the track instead of wire directly to the decoder. We can also use a very small DC down converter since we only have to power the receiver and not additional loads like servos. Note that any DC power supply will do, the battery in this pic will source about 2A at 14.8v.
- The DCC address on the decoder must be set to 3 for the PT Receiver in dead rail mode
- The above are the minimum components, always use a switch harness and a fuse in actual installations
