On and off is handled by the built-in push button, while the rotary knob sets the light level and allows a minimum brightness setting so lamps do not drop out at the low end.\u003c\/p\u003e\u003cp\u003eThis is an AC dimmer intended for interior lighting circuits fed by shore power or an inverter. It is not for 12 V or 24 V DC lighting.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e120 V~ 60 Hz phase-cut dimming with leading-edge or trailing-edge mode selection (LE\/TE).\u003c\/li\u003e\n\u003cli\u003eRated load ranges: 40-500 W incandescent, 40-300 VA electronic transformers, 10-200 W dimmable CFL, 3-200 W dimmable LED.\u003c\/li\u003e\n\u003cli\u003eBuilt-in push button for ON\/OFF with rotary potentiometer dimming.\u003c\/li\u003e\n\u003cli\u003eSupports control from normally-open peripheral push buttons wired in parallel (avoid push buttons with pilot lights).\u003c\/li\u003e\n\u003cli\u003eMASTER-SLAVE function supports up to 3 SLAVE devices when configured as the MASTER, with system load limits that depend on lamp type.\u003c\/li\u003e\n\u003cli\u003eSoft start and soft end behavior, plus flash start support for CFL loads.\u003c\/li\u003e\n\u003cli\u003eShort-circuit and overheating protection with a flashing indicator.\u003c\/li\u003e\n\u003cli\u003eVisible in darkness for easier night adjustments; not suitable for Isoset enclosures.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis dimmer is meant for 120 V AC lighting circuits. All connected lamps and drivers must be marked dimmable, and when multiple lamps are controlled together they should be the same type so the dimming response stays consistent.\u003c\/p\u003e\u003cp\u003eCheck each lamp or driver for the recommended dimming method: LE (leading edge) or TE (trailing edge). Where the load supports both, selecting the mode that matches the lamp is the usual way to reduce flicker and nuisance shutoff.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eTypical installs use a 3-wire connection with neutral present at the device. In retrofit situations where neutral is not available in the box, a 2-wire setup is possible but requires an adapter load installed close to the lamp and wired in parallel.\u003c\/p\u003e\u003cp\u003eFor multi-point switching, use normally-open push buttons in parallel and keep control wiring between the dimmer and the push buttons, or between MASTER and SLAVE devices, within 100 m.\u003c\/p\u003e\u003cp\u003eProtect the circuit with a quick-acting 5 A fuse (F5AH, 250 V~) upstream of the dimmer, and treat installation like any other 120 V AC onboard work: isolate power at the breaker, verify with a meter, and secure conductors so vibration does not loosen connections.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis dimmer fits boats that run 120 V AC cabin lighting and want a knob you can find and adjust in the dark, such as in a salon, stateroom, or galley. It is specified for dry, dust-free locations from 0 C to +35 C, so it belongs in interior spaces rather than cockpits, wet heads, or areas that see washdowns.\u003c\/p\u003e","brand":"Vimar","offers":[{"title":"Default Title","offer_id":52268997181621,"sku":"QBP418486","price":106.4,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1298326_qbp418486.jpg?v=1771541370","url":"https:\/\/www.qualityboatparts.com\/products\/qbp418486","provider":"Quality Boat Parts","version":"1.0","type":"link"}
