The system continuously monitors the mains source. Upon failure or when voltage drops outside acceptable limits, the controller initiates the startup sequence.

The Pramac AC-01 and its variants (AC01, MP, AC01C) are robust and intelligent control systems that provide crucial reliability for standby generators. By managing the full, automatic transition between utility and generator power, they ensure that key systems remain powered even in the event of a total utility failure.

Includes a weekly timer for automatic exercise tests , ensuring the generator stays in peak condition without manual intervention. Protection and Safety

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.

If any parameter goes outside safe operating limits, the panel triggers an alarm and safely shuts down the unit to prevent damage. Electrical Parameter Monitoring

Protects rotating mechanical parts by instantly tripping the fuel solenoid if revolutions exceed safe design specifications. Alternator and Electrical Diagnostics

: It manages the changeover switching (Mains/Genset) by operating contactors within a separate Load Transfer Switch (LTS) or integrated Automatic Mains Failure (AMF) panel. Key Components & Indicators The AC-01 control module typically features:

The Pramac AC 01 system is suitable for a wide range of applications, including:

The fundamental front-mounted component designed with three-phase sensing circuitry to actively track mains voltage levels. It serves as a visual diagnostic point and processing unit for automated power handoffs.

While all share the same core microprocessor logic, they are tailored for different installation needs:

If the generator fails to start on the first attempt, the AC-01 is programmed to follow up with four additional starting attempts automatically.

Continuously senses 3-phase mains voltage. If the mains power fails or falls outside of programmable limits, the system triggers the generator start sequence. Automatic Load Transfer:
