MGC120 Genset Controller Module for AMF Auto Start Stop and ATS Control Overview The MGC120 is a compact genset controller module designed to provide automatic mains failure (AMF) detection, automatic start and stop of the generator, and control of an automatic transfer switch (ATS). Built for small petrol or electric generators, this module delivers reliable basic control and easy integration for backup power and portable power applications. Key benefits Automatic response to mains failure: Detects loss of mains and initiates automatic generator start to restore power without manual intervention. Stops the generator when mains returns, reducing fuel use. ATS control made simple: Drives standard automatic transfer switch mechanisms for seamless transfer between mains and generator supply. Compact and space saving: Small module size fits into generator control panels and compact enclosures where space is limited. Easy integration: Standard wiring points and clear function layout simplify installation into existing genset systems. Durable for field use: Designed for robust operation in generator environments with a practical mounting form factor. Core functions AMF detection and logic for automatic start and stop ATS output control for transfer switch activation Automatic timing and sequencing to protect engine and load during transitions Status output signals for monitoring generator condition and transfer state Compatibility Intended for small genset systems driven by petrol or electric engines Compatible with typical ATS mechanisms used in residential, commercial, and portable generator setups Suited for retrofit or installations where MGC120 style control logic is required Physical and performance attributes Compact module size appropriate for small control panels and enclosures Lightweight construction for simple mounting and wiring Designed to provide consistent automatic control performance for routine backup and portable power needs Practical applications Home backup power: Automate a small standby generator to start on mains outage and switch power back when mains returns. Construction and field work: Control portable petrol generators with automatic start stop and ATS control to maintain power for equipment and lighting. Remote sites and cabins: Provide unattended automatic power switching to protect sensitive loads and maintain comfort systems. Why choose this module The MGC120 focuses on the essential automatic control functions needed in small genset systems: reliable AMF detection, automatic start and stop, and smooth ATS operation. Its compact format and straightforward wiring make it suitable for technicians and installers who need a practical control solution for small generators. Technical note Model identifier MGC120 denotes this specific genset controller module and its AMF and ATS control capabilities. Verify compatibility with your generator engine, starter circuit, and ATS wiring before installation.
