The driver accepts 220-240V 50Hz AC mains input and converts it to constant current DC suitable for driving up to 12W of LED load across three separate CCT zones.\u003c\/p\u003e\n\u003cp\u003eIntended for recessed downlight arrays, architectural cove lighting and commercial installations where CCT tuning and DALI dimming integration are required, the driver fits into ceiling voids or behind panels with a minimum clearance of 30mm around the unit for heat dissipation. The DALI interface allows the driver to be addressed individually on a DALI bus, enabling per-driver dimming control and group zoning from a central controller or wall panel. The three-circuit design supports warm, neutral and cool white LED strips or modules on separate outputs, allowing colour temperature to be adjusted by varying the drive current to each circuit.\u003c\/p\u003e\n\u003cp\u003eThe white plastic enclosure measures approximately 175mm long by 45mm wide by 20mm high, with cable entry knockouts at both ends for input mains and output DC connections. IP20 rating limits use to dry interior locations only. The driver carries CE marking and is designed to operate in ambient temperatures between -20°C and +45°C without additional forced cooling. The constant current regulation maintains stable output across the full dimming range, preventing colour shift or flicker as the LED load dims.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e12 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Current\u003c\/td\u003e\n\u003ctd\u003e300 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl Protocol\u003c\/td\u003e\n\u003ctd\u003eDALI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour Temperature Circuits\u003c\/td\u003e\n\u003ctd\u003e3 (CCT tunable)\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\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e220-240V AC 50\/60Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eYes (DALI protocol)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePlastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-20°C to +45°C\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\/PSL-DL40-3CCT-150-300mA-DE_datasheet.pdf?v=1783054866\" target=\"_blank\" rel=\"noopener\"\u003eProduct manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\u003cp\u003e\u003cstrong\u003eWhat does constant current mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eConstant current drivers regulate the output current (300mA in this case) rather than voltage, which is the preferred drive method for most LEDs.
