AMF25 AMF20 Diesel Generator Controller Auto Start Genset Control Module with LCD Display and Electric Controls Product overview A compact and reliable genset controller designed for automatic start and stop of diesel generator sets. The AMF25 controller also supports AMF20 compatibility and provides a clear LCD display for status, alarms and parameter configuration. Built for panel mounting in generator control panels, this module centralizes starter control, monitoring and protection functions. Key benefits Automatic response to power loss: Detects mains failure and starts the generator automatically, then returns to mains when power is restored. Reduces downtime and removes the need for manual intervention. Clear status and simple setup: Backlit LCD provides operational readouts and alarm messages, making system status easy to read and parameters straightforward to configure. Flexible control and integration: Standard inputs and outputs allow connection to typical diesel engine starter systems and to external alarms or shutdown devices. Supports both auto and manual operating modes. Reliable operation: Designed for continuous genset control with stable logic for start, stop and fault handling. Compact and panelfriendly: Space efficient control module suitable for retrofits or installations where a clean control interface is required. Functions and features Auto mains failure detection and automatic engine start and stop LCD display for voltage, frequency, run hours, operational status and alarm codes Selectable auto and manual modes for operator flexibility Engine protection and fault indication through dedicated alarm outputs Standard control interface for starter motor, fuel shutoff and shutdown relays Configurable timers and thresholds for soft start and stable operation Compatibility and installation Models covered: AMF25 and AMF20 genset control modules Compatible with diesel engine generator sets using standard starter, ignition and shutdown circuits Suitable for panel mounting in generator control panels or enclosures Typical wiring to alternator sensing, starter contactor, battery supply and shutdown interlocks Performance and materials Designed for stable electrical control of diesel gensets with reliable start and stop sequences Durable enclosure and connectors for use in generator control compartments User interface optimized for clear visibility and straightforward configuration Practical use scenarios Backup power for commercial buildings: Automatically starts building standby generators when utility supply is lost and returns to mains supply when restored, keeping critical systems online. Construction and remote sites: Provides dependable auto start control for portable diesel gensets used on sites without permanent supervision. Telecommunications and remote equipment shelters: Maintains uninterrupted power by initiating generator operation on mains failure and managing safe shutdowns on generator faults.
