Electronic DC lighting dimmer for marine, caravan and mobile lighting systems

Controls the brightness of compatible filament lighting in boats, motorhomes, caravans and coaches, supporting incandescent, halogen and xenon lamps. The compact marine-grade housing incorporates efficient heat dissipation, protected terminals and tropicalised circuit boards to support reliable operation in demanding mobile and marine environments.

Key Features

• Variable lighting control: Provides adjustable output from 10% to 98% of the input voltage for flexible lighting levels.
• Brightness memory: Stores the current brightness setting when switched off and restores the same level when lighting is switched back on.
• Soft start operation: Limits lamp inrush current during start-up to help extend the service life of filament lamps.
• Self-diagnostics: Tri-colour LED indicates standby, load operation, short circuit and over-temperature conditions for easier system troubleshooting.
• Integrated protection: Includes short-circuit protection, over-temperature protection and internal fuse protection for the electronics.
• Temperature failsafe: Automatically reduces the lighting circuit to 50% of rated load if excessive operating temperature is detected.
• Master/slave operation: Selectable master/slave functionality allows multiple dimmers to be connected in parallel for higher-power lighting installations.
• Marine-grade construction: Uses a marine-grade anodised aluminium enclosure with non-ferrous hardware, plated brass terminals and tropicalised circuit boards.

Suitable for controlling higher-power DC lighting circuits where adjustable brightness, diagnostic monitoring and electrical protection are required. Multiple momentary switches can also be used to provide lighting control from different locations.
