View Spec Sheet

The Cummins Power Generation series CHPC PowerCommand® automatic transfer switch monitors the primary power source, signals the generator to start upon loss or destabilization of utility power, and then automatically transfers the load to the generator. Once the utility power source becomes available and stable, the CHPC will return the load to the primary source without power interruption by temporarily paralleling both sources for less than 100 msecs.
