Product overview
The DEIF AGC 150 Generator Marine is a compact controller for the control, protection and monitoring of marine diesel-generator sets.
It automatically manages engine starting and stopping, generator measurements, alarms, shutdowns and circuit-breaker control. Its front panel incorporates a graphical display, operating buttons and configurable status LEDs. Official DEIF AGC 150 Generator Marine page.

Generator protection functions
Depending on configuration, the controller can provide:
- Overvoltage and undervoltage protection
- Overfrequency and underfrequency protection
- Generator overcurrent protection
- Reverse-power protection
- Overload protection
- Unbalanced-voltage and current monitoring
- Loss-of-excitation monitoring
- Earth-fault monitoring
- Emergency-stop shutdown
- Overspeed and underspeed protection
- Low lubricating-oil pressure shutdown
- High cooling-water temperature shutdown
Engine communication
The AGC 150 can communicate with supported electronic engine-control units using CAN bus. This allows the controller to display and monitor information such as:
- Engine speed
- Coolant temperature
- Lubricating-oil pressure
- Fuel consumption
- Battery voltage
- Engine operating hours
- Diagnostic trouble codes
- Exhaust after-treatment status
Actual data availability depends on the engine ECU and selected communication protocol.
Marine applications
- Auxiliary diesel generators
- Emergency generators
- Harbour generator sets
- Offshore generator packages
- Workboats and tugboats
- Cargo vessels
- Tankers
- Passenger vessels
- Generator retrofit panels
- Engine-driven pumps
- Small independent marine power systems
Main features
- Designed for harsh marine environments
- Generator control and protection in one unit
- IP65 front panel
- Wide operating-temperature range
- Configurable LEDs and pushbuttons
- Built-in communication interfaces
- Engine-CAN integration
- Event and alarm recording
- PC or front-panel configuration
- Compact installation depth
- Suitable for new generator panels and retrofits
Important variant warning
The AGC 150 family includes several different controllers:
- AGC 150 Generator
- AGC 150 Generator Marine
- AGC 150 Stand-alone
- AGC 150 Mains
- AGC 150 BTB
- AGC 150 PMS Lite
- AGC 150 Hybrid
- AGC 150 Engine Drive
- AGC 150 Remote Display
The software package determines which controller functions are available. The marine generator configuration should therefore be confirmed before ordering.
