AMF20 Diesel Generator Controller with Auto Start Control, Fault Protection and PC Monitoring

AMF20 Diesel Generator Auto Start Controller Overview A microprocessor-based generator controller designed for reliable automatic start/stop control, monitoring, and fault protection of diesel generator sets. Compatible as a direct replacement with original genset control units and suitable for OEM integration. Key Benefits Reliable automatic operation for unattended backup power and seamless transfer to generator supply when mains fail. Flexible configuration to match a wide range of engine and alternator interfaces, minimizing installation time. Clear on-panel display with selectable English or Chinese interface for easy local operation. PC connectivity for remote setup, monitoring, and diagnostics. Core Functions High-performance microprocessor implementing complex control, protection, and monitoring tasks. LCD display with selectable English and Chinese interfaces for user-friendly status and configuration. Automatic monitoring, pre-warning, and controlled shutdown on fault conditions to protect engine and alternator. Fully configurable on-panel parameters including current transformer settings, flywheel tooth count, idle run time, and more. RS232 and USB communication ports for PC connection, configuration, and live monitoring. Six user-programmable auxiliary inputs and six configurable auxiliary outputs for start, alarm, shutdown, or custom functions. Support for expansion modules to add extra inputs and outputs as required. Automatic start and stop in automatic mode. When mains input is lost and a mains monitoring relay or auxiliary input is provided, the controller starts the genset and supplies the load. When mains returns, the controller returns the load to mains and stops the genset. Compatibility and Quality Designed as a compatible replacement for original genset control units, fitting common AMF20 installations. OEM-friendly and configurable to suit a variety of diesel generator applications. Provided with a one-year warranty. Typical Use Scenarios Emergency backup for commercial buildings: automatic detection of mains failure and fast start to restore critical power for lighting, servers, and HVAC. Industrial site power control: integration with site PLC and alarms using programmable auxiliary I/O to coordinate shutdowns and safety sequences. Rental and service fleets: quick replacement controller for gensets in the field, with PC connectivity for onsite configuration and troubleshooting. Technical Highlights Model compatibility: AMF20 User interface: LCD with selectable English and Chinese Communications: RS232 and USB for PC connection Aux I/O: 6 programmable inputs and 6 programmable outputs Expandability: Supports modular expansion for additional I/O Functionality: Monitoring, alarm, controlled shutdown, automatic start/stop, parameter configuration This controller provides a compact, configurable, and dependable solution for diesel generator automatic start control and protection while remaining compatible with original genset control parts.
