Description
The ELCOS CAM-410/20 (Part No. 00242209) is a microprocessor-based Automatic Mains Failure (AMF) control unit specifically designed for standby generator sets. It monitors the mains (utility) power supply and automatically triggers the generator start sequence when a failure is detected, manages the transfer switch, and monitors engine parameters (such as oil pressure, coolant temperature, and frequency) to ensure safe and reliable backup power operation.
