Functional Description
Speed Control

Maintains precise engine speed under varying loads.

Adjustable droop (for generator applications) or isochronous (constant speed) modes.

Load Sharing (Parallel Operation)

Enables multiple engines to share load proportionally in genset applications.

Supports kW (kilowatt) load balancing for synchronized generators.

Protection & Alarms

Overspeed/Underspeed shutdown

Loss of speed signal detection

Configurable fault responses (alarm, derate, or shutdown).

Flexible I/O Options

Analog inputs for process control (e.g., pressure, temperature).

Digital inputs for start/stop, fault reset, etc.

User Interface

LCD display for real-time monitoring (speed, load, alarms).

Password-protected settings to prevent unauthorized changes.

Typical Applications
Power Generation: Genset control (standalone or parallel).

Marine: Main propulsion and auxiliary engine control.

Industrial: Gas compressors, pumps, and turbine control.
