- Power Supply (Note: 110vAC only - not for 240vAC power)
- Detailed instructions
The PowerPax is microprocessor controlled. When hooked up for programming, the PowerPax initially provides power to the programming track to charge-up decoder components like capacitors that would otherwise reduce programming energy and cause a programming failure. When you initiate the programming sequence through your DCC System, the PowerPax also boosts and controls the programming energy to about 200 mA. In the event of an overload or short the PowerPax instantly shuts down to protect the decoder and your DCC System’s programming circuits.

The PowerPax connects in series between the programming track output of your DCC System and your isolated Programming Track. You may leave the unit permanently installed for all programming. Warning: Do not connect to DCC track output or use for Operations Mode (Mainline) programming or unit will be damaged.
The PowerPax has been thoroughly tested for compatibility and functionality with Broadway Limited locos, MRC, NCE, Digitrax, Lenz, TCS and Soundtraxx decoders in both single and dual decoder configurations with complete success. PowerPax also works with programming software, RR&Co (Train Programmer) and JMRI (Decoder Pro).
