Don't let power outages cripple your operations! In today's demanding environment, a reliable and continuous power supply is not just a luxury, but a necessity. Our state-of-the-art Automatic Changeover & AMF (Automatic Mains Failure) Panel is engineered to provide seamless transition between your main utility supply and a backup generator, ensuring your critical systems remain operational and your business stays productive, no matter what.
What is an Automatic Changeover & AMF Panel?
An AMF Panel is an integrated control system designed to automatically monitor the main utility power supply (mains) and, upon detecting a failure or deviation, automatically start a connected backup generator. Once the generator is stable, it transfers the electrical load from the mains to the generator. When the mains power returns and stabilizes, the panel automatically re-transfers the load back to the mains and safely shuts down the generator after a cool-down period. This entire process is fully automated, requiring no human intervention.
Key Features & Capabilities:
Our Automatic Changeover & AMF Panels are built with precision and packed with features to deliver unparalleled performance and reliability:
Automatic Mains Failure (AMF) Functionality:

Configurable to single-phase or three-phase systems.
Tailored to specific client needs, including additional control features, remote monitoring (Modbus, GSM), and specialized protection.
Benefits of Choosing Our AMF & Changeover Panel:
Uninterrupted Power Supply (UPS): Ensures continuous operation of critical systems, preventing costly downtime and data loss.
Enhanced Equipment Protection: Safeguards sensitive electronics and machinery from damaging power fluctuations and faults.
Reduced Manual Intervention: Eliminates the need for human presence to manage power transitions, especially during emergencies.
Cost Savings & Efficiency: Optimizes generator usage, reducing fuel consumption and wear-and-tear through intelligent control.
Safety & Compliance: Built to relevant industry standards, minimizing risks to personnel and equipment.
Peace of Mind: Provides reliability and security, knowing your power supply is intelligently managed.
How It Works: The AMF Cycle
Mains Monitoring: The AMF panel continuously monitors the main utility power supply for voltage, frequency, and phase stability.
Mains Failure Detection: If the mains power fails or deviates from acceptable limits, the panel detects the fault after a pre-set delay.
Generator Start: The panel sends a start command to the backup generator. It monitors the generator's status (cranking, oil pressure, speed) until it reaches stable operating conditions.
Load Transfer: Once the generator is stable and ready to accept load, the panel opens the mains breaker/contactor and then closes the generator breaker/contactor, transferring the entire electrical load to the generator.
Mains Return: The panel continues to monitor the mains supply. When the mains power returns and stabilizes for a pre-set period, it initiates the re-transfer process.
Load Re-transfer: The panel opens the generator breaker/contactor and closes the mains breaker/contactor, transferring the load back to the main utility supply.
Generator Cool-down & Stop: After transferring the load, the generator is allowed to run on no-load for a specified cool-down period before receiving a stop command, ensuring its longevity. The panel then resets, ready for the next event.
