Transformer Compatibility
Proto-Sound 2.0 is designed to work with most standard DC power supplies and AC
transformers. The following charts lists the recommended DC and AC transformers.
Note that many of the AC operational commands described in these instructions require
a bell button, so if your AC transformer does not have its own bell button, you should
consider adding one to get the full benefit of the system. In addition, the chart details
how the terminals on these transformers should be attached to your layout. DC
transformers employing PWM (pulse width modulation) should not be used with the
separately sold DCS system.
