Advanced logic ensures precise timing, monitoring, and control.
The AC-01 mitigates risks by linking real-time engine telemetry with an integrated digital display and flashing fault indicator lights. When values cross critical safety parameters, the module alerts operators or executes an automated engine shutdown.

The LED indicators on the AC01 are color-coded for quick status recognition:
The is a micro-processed control unit used in automatic standby generator sets (Gensets). Its primary purpose is to monitor the utility power source and the generator, managing the transition between them to ensure uninterrupted or minimal-interruption power supply to critical loads. Key Components & Terminology AC-01: The core microprocessor control unit.
Shows real-time parameters, alarm messages, and operating status. 2. Key Features and Capabilities (AC01-MP & AC01C) pramac ac 01 generator monitor control system ac01 mp ac01c
: Allows for scheduled or manual testing under load to ensure system readiness. Maintenance Tip: The Importance of the "Weekly Test"
: Engineered with a space-saving physical enclosure footprint or updated communication ports. It allows for clean physical integration into cramped spaces like Nautical Marine marine control consoles or remote standalone changeover enclosures. Step-by-Step Sequence of Automatic Operations
Monitors battery voltage, charging current, and engine status (running hours, start counter) to ensure reliability during critical outages.
The system includes protections to prevent damage to the engine and alternator: Automatic Shutdowns: Parameter Group Sensor Signal Checked Module Safety Action
Once the generator achieves proper voltage and frequency, the AC-01 closes the genset contactor, transferring the load to the generator. Phase 3: Restoration
The controller opens the main power supply breaker in the load transfer switch (LTS) panel to isolate the load from the failed grid. Startup Sequence: The generator is started automatically.
Typically a compact or specific configuration variant of the standard AC-01 controller. Integrated Features:
: The controller activates the generator's fuel solenoids and glows glow plugs (if applicable), then closes the starter motor relay until the engine reaches its nominal RPM state. the AC-01 closes the genset contactor
This is the standard controller found on many Pramac portable and light commercial generators. It provides a clear alphanumeric display showing voltage, current, frequency, and engine hours. Navigation is via a simple four-button membrane keypad. It is ideal for applications like retail backup, small farms, or construction sites where three-phase monitoring is not required.
: The "set and forget" mode. The AC-01 will automatically manage the start sequence, opening the mains contactor and closing the generator contactor upon power loss.
A standout feature of this system is its , which allows you to customize the generator's behavior for specific scenarios:
