When the mains power fails or drops out of acceptable voltage limits, the AC-01 automatically detects the fault, starts the generator, and transfers the load. Once stable grid power returns, it handles the transition back and initiates a cooling cycle for the engine. Key Features & Technical Capabilities
System operators configure the system into several distinct operational modes depending on application demands:
The controller tracks the voltage, balance, and frequency profiles across all three phases of the mains electrical supply line. pramac ac 01 generator monitor control system ac01 mp ac01c
The "C" model is a stripped-down version aimed at price-sensitive markets. It replaces the full alphanumeric LCD with a combination of bright LED status indicators (Mains On, Generator On, Load On Generator, Alarm) and a smaller digital readout. While it loses some advanced programming features, it retains the essential AMF logic and engine protection. The AC01C is common on entry-level automatic standby generators for home use.
Unlike basic manual control boards, the AC01 series offers a digital interface that provides real-time data and protection logic. The variant typically refers to the specific controller unit mounted within the panel. When the mains power fails or drops out

The "MP" suffix denotes a significant upgrade. This unit includes —a critical feature for grid-tied or industrial applications. Decoupling ensures that the generator does not accidentally back-feed into a de-energized utility line, protecting line workers and equipment. Additionally, the AC01 MP adds RS232 or RS485 serial communication, allowing the generator to connect to a building management system (BMS) or remote monitoring software via Modbus protocol. This makes the MP variant suitable for data centers, hospitals, and factories that require remote telemetry. The "C" model is a stripped-down version aimed
A key feature of the architecture is its adaptability to remote environments. The control board features serial communication interfaces that permit direct physical tethering to a local PC.
