An Automatic Mains Failure (AMF) Panel is an intelligent control system that automatically detects utility mains failure and, without any manual intervention, starts the standby diesel generator, transfers the electrical load, and restores the mains supply once it returns to normal. Also known as an Auto Transfer Switch (ATS) panel, it ensures zero or minimal disruption to critical loads during power outages. Our AMF panels incorporate a dedicated microprocessor-based controller that continuously monitors the mains supply for undervoltage, overvoltage, phase loss, and frequency deviation. Upon detecting a fault, it initiates the DG start sequence, verifies rated voltage build-up, and performs a safe interlocked changeover. When mains normalizes, the panel automatically retransfers the load and shuts down the generator after a safe cooling period ? delivering fully automatic, reliable standby power for hospitals, data centres, industries, commercial buildings, and telecom infrastructure
