The Pramac AC-03 is a microprocessor-based controller designed for single generating sets operating in standby or prime power modes. Often built on the ComAp InteliLite NT platform, it serves as the central interface for monitoring engine parameters, controlling generator output, and managing automatic mains failure (AMF) functions.
