Application Scenarios: Gas engines inside marine engine rooms, marine gas generator sets, non-explosion-proof engine room control cabinet interiors on offshore platforms.
Material Composition: Sheet metal enclosure; circuit board sprayed with triple-proof moisture-proof and salt-fog-resistant coating; corrosion-resistant gold-plated terminals; flame-retardant insulation components.
Structural Features: Panel-mount structure, rear terminal blocks, appearance consistent with land-based models, nameplate marked with maritime certification information.
Working Principle: Control logic consistent with land-based standard version; hardware circuit adds salt-fog and marine strong electromagnetic interference resistance treatment, completing engine speed, fuel, and protection control.
Installation Requirements:
-
Panel-mount inside marine control cabinet, not in direct contact with salt-fog moisture; avoid ship hull vibration, add shock-absorbing installation accessories
-
All signal cables use marine shielded cables, strictly ground according to classification society wiring specifications
-
Ventilation and heat dissipation, away from marine high-power power equipment
Usage Precautions:
-
Although circuit board has triple-proof treatment, the controller body cannot be directly exposed to salt-fog environment, must be placed inside sealed control cabinet
-
Static electricity protection, prohibit hot-plugging terminals; marine power fluctuations must add filtering devices
