AMF Controller
In high-traffic telecom sites and core network facilities, a single DG set is often insufficient to guarantee uptime during prolonged mains failure, and manual coordination between multiple generators can lead to delayed changeover, load imbalance, increased fuel consumption, and risk of site outage. The AMF Panel – Dual DG Configuration by Intelux is an advanced automatic power management solution designed to intelligently control, monitor, and coordinate two diesel generator sets along with the utility supply to ensure uninterrupted power availability.
The system continuously supervises mains health and, upon failure, automatically selects and starts the appropriate DG, manages load transfer, and provides protection and interlocking between generators to prevent parallel operation faults. It also supports sequential DG operation, load sharing logic (as per configuration), automatic retransfer to mains, and optimized DG run hours, improving fuel efficiency and reducing wear.
Engineered for telecom MSCs, data centers, switching facilities, large BTS hubs, and mission-critical infrastructure, the Dual DG AMF panel delivers high reliability, operational safety, intelligent power distribution, and reduced manual intervention, making it a vital component of telecom power and energy systems where uptime, redundancy, and automation are essential.
