The driver maintains steady current to the connected LED module regardless of minor voltage fluctuations, which helps prolong LED lifespan and prevent premature failure caused by current spikes.\u003c\/p\u003e\n\u003cp\u003eDesigned for integration into pendant lights, wall sconces, downlights and architectural fittings where the driver can be concealed within the ceiling void, wall cavity or luminaire body, the unit measures 98mm x 39mm x 22mm and weighs approximately 60g. The compact size allows it to fit inside most ceiling roses and pendants with sufficient internal volume. The driver requires 230V 50Hz mains input and outputs 18-35V DC depending on the connected LED load.\u003c\/p\u003e\n\u003cp\u003eThe DIM350DA is dimmable when paired with trailing-edge LED-compatible dimmers. Compatibility with specific dimmer models varies, so testing with the exact dimmer switch and LED module combination is recommended before full installation. The polycarbonate case carries Class II double-insulated construction and an IP20 rating, meaning it must be installed in dry indoor locations only and cannot be exposed to moisture or outdoor conditions.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e98 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e22 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e39 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePolycarbonate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClass\u003c\/td\u003e\n\u003ctd\u003eII\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e230V 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eTrailing-edge only*\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDriver Type\u003c\/td\u003e\n\u003ctd\u003eConstant Current\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_882886_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does constant current mean and why does it matter?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eConstant current drivers maintain a fixed current output (in this case 350mA) regardless of minor voltage fluctuations.

Leading-edge dimmers are not supported. Test the driver with your exact dimmer and LED combination before full installation to confirm smooth dimming without flicker.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere can the driver be installed?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe IP20 rating means the driver must be installed in dry indoor locations only. Typical installation locations include ceiling voids above plasterboard, inside pendant light canopies, within wall sconce bodies, or in recessed downlight housings where the unit is protected from moisture and physical contact.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat LED wattage range does it support?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe driver supports LED loads from 1W to 12W at 350mA constant current. The output voltage adjusts automatically between 18V and 35V depending on the connected load.
