Overview

The Vimar MASTER dimmer 120V is a push-button universal dimmer for 120 V~ 60 Hz AC lighting circuits, using phase-cut dimming for a mix of dimmable load types. It supports 40-400 W incandescent, 40-300 VA electronic transformers, 10-200 W dimmable CFL, and 3-200 W dimmable LED loads when the lamp or driver is rated for phase-cut dimming.

On board, this style of dimmer is commonly used on boats with 120 V AC cabin or saloon lighting fed from shore power or an inverter. The unit is rated IP40 and is meant for protected interior mounting, not exposed cockpit or deck locations where spray and washdowns are expected.

The variants differ by visible color only. Electrical rating, functions, and load handling remain the same across the range.

Compatibility and fit

This is an in-wall, flush-mount module intended for Vimar ARKÉ wiring device installations. Allow clearance behind the panel: the device body is approximately 50.7 mm deep, with a front module size around 22.3 mm wide and 49 mm high. It is not intended for Isoset enclosures.

Installation and setup

Wiring is typically a line and load connection with optional normally-open push buttons for multi-point control. Keep all controlled lamps and drivers consistent on the same circuit, and confirm every load is explicitly rated as dimmable with phase-cut control before commissioning. Set the minimum brightness so LEDs stay stable without flicker at low levels.

Use on board

This dimmer is a good match for boats that run 120 V AC lighting in cabins, berths, or lounge areas and want a familiar wall control with low-level lighting for night passages or dockside living. It is not a controller for 12 V or 24 V DC lighting circuits.

Maintenance and care

Use a dry or lightly damp cloth on the front surface. Avoid spray cleaners and keep the device out of areas exposed to saltwater mist, washdowns, or direct weather.
