A power system is configured to provide a regulated voltage to an electrical load connected to a power source through at least one power line. The power system includes a first voltage control loop based on a remote sense signal indicative of voltage level at the load. The power system further includes a second voltage control loop based on a local sense signal indicative of a level of output voltage at the power source. The voltage level of the local sense signal is generally at a higher voltage level relative to the voltage level of the remote sense signal. Circuitry is configured to pass just the signal with the higher voltage level to ensure that the local sense control loop is a dominant control loop with respect to the remote sense control loop. This avoids effects on the power source from one or more failure modes that can occur in interconnections of the system.
