Overview
The AMF25 is a microprocessor-based generator set controller that provides automatic engine start/stop sequencing, AC power monitoring, and alarm protection for single diesel or gas generator units. It integrates digital measurement, programmable logic, and communication interfaces into a single panel-mounted module.
Key Features
- Microprocessor Control — Digital MCU-based module with precise engine start/stop sequencing and generator protection for single diesel/gas generator sets
- True RMS AC Monitoring — Generator and mains voltage, current, frequency, kW, kVA, PF measurement with programmable CT ratios and alarm thresholds
- CANbus J1939 Engine Integration — Direct communication with electronic engine ECUs for parameter display and diagnostic trouble code reading
- Multi-Mode Operation — Manual, automatic, and test modes with configurable transfer sequences and programmable crank/rest cycles
- Flexible I/O — All digital inputs and relay outputs user-configurable for custom applications including pre-heat, ventilation, annunciation, and remote signaling
- Event History — Onboard real-time clock with event log for commissioning, troubleshooting, and maintenance tracking

Selection Advice
Mid-range AMF controllers differ primarily in feature combinations. The DSE4520 uniquely offers fuel theft detection — a significant advantage in African and Middle Eastern markets where fuel is expensive. Multi-brand CANbus support makes it plug-and-play on Volvo/Scania engines. The AMF25 has the smallest panel cutout (120×90mm), making it the preferred choice for retrofitting older controllers. The DKG309 uniquely offers SMS alarm notification, the most I/O, and CANopen support. Choose based on the customer’s specific requirements.
