In its basic version, the PMC is used Power supply protection function, 3-phase to switch generators to the power grid and is also suitable for use in stand-by power supply facilities. The system is designed to be used for isolated and parallel operation. An automatic start and synchronisation function is additionally implemented to accelerate the generator, set to nominal speed as well as to synchronise and close the power circuit breaker. The power requirements are defined by a higher-level system. An automatic facility that controls load balancing, opening of the power circuit breaker and stopping of the propulsion system is also integrated for the purpose of shutting down the generator. The Power Management Controller is equipped with an integrated power supply and system protection function.
