Detailed content
Functional Features:
-
All marine basic functions of 9906-727
-
Adds lean-burn low-NOx emission closed-loop control
-
Maritime event log recording
-
Marine system communication interface
Application Scenarios: River and ocean-going vessel gas generator sets, marine gas-driven auxiliary machinery, engine room equipment needing to meet maritime emission regulations.
Material Composition: Sheet metal enclosure; circuit board triple-proof moisture-proof and salt-fog-resistant coating; corrosion-resistant gold-plated terminals; flame-retardant insulation components.
Structural Features: Panel-mount type, rear wiring terminals, appearance consistent with same series, nameplate identifies maritime certification.
Working Principle: On the basis of marine anti-interference hardware, executes speed regulation, fuel closed-loop, lean-burn emission control, and marine-adapted fault alarm shutdown logic.
Installation Requirements: Marine control cabinet panel-mount, shock-absorbing installation; all signal cables use marine shielded cables; strict grounding, away from high-power electromagnetic equipment.
Usage Precautions: Controller placed inside control cabinet, prohibit direct exposure to engine room salt-fog; prohibit hot-plugging terminals; add filters to power supply to suppress marine grid disturbances.
