MGC120 Genset Controller AMF Auto Start Stop ATS Switching Control Panel Module Overview A compact control module designed to provide automatic mains failure detection, automatic engine start and stop, and automatic transfer switch control for small gasoline generators. The MGC120 simplifies generator management and enables unattended operation of backup and portable power systems. Key benefits Automatic response to mains failure: Detects loss of utility power and starts the generator automatically to restore power without manual intervention. Seamless transfer control: Controls ATS switching so essential loads are transferred to the generator and returned to mains when utility power is restored. Compact and space efficient: Small form factor fits inside control panels on compact gasoline generators and portable gensets. Simplifies operation: Reduces need for manual start, stop, and transfer, making the generator easier to use in backup and remote applications. Reliable control functions: Designed specifically for AMF, auto start stop, and ATS switching tasks required by small genset systems. Function and compatibility Functions: AMF mains failure detection, automatic start and stop of the engine, automatic transfer switch control, and control panel module functionality. Compatibility: Intended for use with small gasoline generator sets and portable gensets that accept the MGC120 controller format. Suitable for integration with standard ATS and generator control circuits used in small power systems. Size and installation: Small, panelmountable module ideal for limited space installations. Designed to be mounted within the generator control area or switchgear enclosure. Construction: Built as a dedicated control module for genset applications. Intended for professional installation and wiring by qualified personnel. Performance highlights Enables unattended operation with predictable start and stop sequences. Coordinates ATS switching to minimize interruption to critical loads. Provides consistent control logic for small generator sets used in backup and portable power scenarios. Typical applications Home or small business backup power: Automates startup and transfer to generator when utility power fails, then returns loads to mains when service is restored. Construction sites and portable power: Controls small gasoline generators used to power tools and equipment, allowing reliable automatic start and stop and transfer of critical circuits. Remote cabins, kiosks, or equipment shelters: Provides unattended generator control for seasonal or remote locations where manual operation is impractical. Installation and use notes Intended for integration into generator control panels and ATS systems. Follow wiring diagrams and installation instructions appropriate for the generator and switchgear used. Installation and testing should be performed by a qualified technician familiar with genset and ATS wiring and control logic. Verify compatibility with the generator set and ATS before installation to ensure correct control interfaces and signal levels. Summary The MGC120 is a compact AMF and ATS control module that automates start, stop, and transfer functions for small gasoline generator sets. It is designed to simplify generator operation, support unattended use, and integrate into compact control panels for backup, portable, and remote power applications.
