Tridonic LED Driver LCA 45W 500-1400mA Dali Dimmable

Tridonic LCA 45W 500-1400mA DALI is a dimmable constant current LED driver designed for professional lighting applications requiring precise and flexible light output control. Its compact white polycarbonate housing, measuring 215 × 70 × 31 mm, makes it ideal for installation in suspended ceilings, luminaires and integrated systems for indoor use, with a protection rating of IP20 and insulation class II.

The driver operates in constant current mode, with an output current freely selectable between 500 and 1,400 mA, covering a power range from 25 W up to 45 W depending on the set current. The input voltage is 220-240 V, compatible with the main international standards (EU, AUS, USA, UK, JAP). Dimming is achieved via the DALI / DALI-2 protocol, with an operating range spanning from 1 to 100% across the entire operating window, ensuring smooth and flicker-free regulation. Efficiency reaches up to 90%, while standby power consumption remains below 0.15 W. The nominal lifespan is rated at up to 100,000 hours, ensuring long-term reliability. The integrated strain relief with loop-through function simplifies wiring in daisy-chain installations.

The available output current variants allow precise system configuration: at 500 mA the output power is 25 W, at 600 mA it reaches 30 W, at 700 mA 35 W, at 800 mA 40 W, and at 900 mA 45 W. From 900 mA up to 1,350 mA the maximum output remains constant at 45 W, while at 1,400 mA it settles at 44.9 W. This wide adjustment range makes the driver compatible with a broad selection of LED modules, allowing luminous flux to be optimised according to the specific requirements of each lighting design project.
