Operating across a 9-33VDC input range, these dimmers use normally-open momentary push-button switches to control low-voltage lighting circuits from one or multiple locations.\u003c\/p\u003e\u003cp\u003eThe range includes single-channel models and the two-channel DuoDim configuration, with different power capacities to accommodate lighting circuit loads. Soft-start operation reduces initial current surges to filament lamps, while brightness memory restores the previous lighting level when switched on again.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e9-33VDC input range for 12V and 24V lighting systems.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eMomentary push-button control with support for multiple switch locations.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSoft-start function and brightness-level memory.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eShort-circuit, transient-voltage, and overtemperature protection.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eCorrosion-resistant terminal connections with insulated barriers.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThe Intervolt SLD series is available in multiple configurations with different power ratings and lighting circuit control arrangements.\u003c\/p\u003e\u003cp\u003eThe single-channel models control one lighting circuit, while the DuoDim model supports two independently controlled circuits or combined operation through a single switch.

Compatibility with LED fixtures depends on their internal electronics and should be confirmed before installation.\u003c\/p\u003e\u003cp\u003eInstallation requires appropriately rated wiring and circuit protection, with sufficient ventilation around the dimmer housing for heat dissipation. The connected lighting load must remain within the rating of the selected model and operating voltage.\u003c\/p\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003eILSLD2040DD\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003eILSLD2040DC\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003eILSLD2550DC\u003c\/span\u003e","brand":"Imtra","offers":[{"title":"9-33VDC 400W","offer_id":52063288131830,"sku":"APL789456-V3","price":226.0,"currency_code":"USD","in_stock":true},{"title":"12\/24V 200\/400W","offer_id":52063288164598,"sku":"APL789456-V1","price":163.0,"currency_code":"USD","in_stock":true},{"title":"12\/24V 250\/500W","offer_id":52063288197366,"sku":"APL789456-V2","price":211.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0809\/6658\/2518\/files\/ilsld2040dd-1-upscaled-nobg-optimized.webp?v=1793200168","url":"https:\/\/www.apollolighting.com\/products\/apl789456","provider":"Apollo Lighting","version":"1.0","type":"link"}
