High-capacity DC lighting dimmer for marine and mobile lighting systems
Controls the brightness of higher-load DC lighting circuits across boats, motorhomes, caravans and coaches. The electronic switchmode design supports compatible filament lamps including incandescent, halogen and xenon lighting, while the compact marine-grade enclosure incorporates efficient heat dissipation and protected electrical connections for demanding installations.
Key Features
- High-capacity lighting control: Supports higher-power DC lighting circuits with continuous load ratings suitable for both 12V and 24V systems.
- Variable dimming: Provides adjustable output from 10% to 98% of input voltage for flexible control over lighting levels.
- Brightness memory: Records the selected brightness when the lights are switched off and restores the same setting when switched back on.
- Soft start operation: Limits start-up inrush current to help extend the operating life of compatible filament lamps.
- Self-diagnostics: Tri-colour LED provides status indication for standby mode, connected load, short circuit and over-temperature conditions.
- Integrated protection: Incorporates short-circuit, excessive-temperature and internal fuse protection for the electronics.
- Temperature failsafe: Automatically reduces the lighting circuit to 50% of rated load if excessive temperature is detected.
- Master/slave functionality: Selectable master/slave operation allows multiple dimmers to be connected in parallel where additional lighting capacity is required.
- Marine-grade construction: Features an anodised marine-grade aluminium enclosure with electrical-grade end caps and a temperature-resistant terminal cover.
- Flexible switching: Operates from a normally open momentary push switch and supports multiple switches within the same lighting circuit.
Suitable for higher-capacity DC lighting installations requiring adjustable brightness, diagnostic monitoring and integrated circuit protection. Parallel operation provides additional flexibility for larger lighting systems where multiple dimmers are required.
