Overview
The AMF20 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
These three standard AMF controllers are closely positioned. The DSE3110’s unique selling points are dual CANbus and the highest global brand recognition with the most comprehensive technical documentation. The AMF20 is ComAp’s classic AMF model, widely pre-installed by European generator OEMs, with intuitive LiteEdit software. The DKG307 offers the most I/O at a moderate price, with dense dealer networks in the Middle East, Africa, and Southeast Asia for strong localized support. If uncertain, the DSE3110 is the safest choice — electricians familiar with it can be found worldwide.
