Tridonic LED Driver LCA 45W 500-1400mA one4all C PRE Dimmable

Tridonic LED Driver LCA 45W 500-1400mA one4all C PRE Dimmable is a constant current LED driver designed for built-in installation in class I and class II luminaires. With a maximum output power of 45 W and an adjustable output current from 500 to 1400 mA in 1 mA steps, it delivers outstanding operational flexibility. The compact PVC housing — measuring 120 × 70 × 22.3 mm — features a protection rating of IP20 and is compatible with LED light sources operating at an input voltage of 220-240 V.

This driver stands out for its one4all interface, supporting DALI-2 DT6, DSI, switchDIM and corridorFUNCTION protocols, as well as configuration and dimming via ready2mains and programming through I-SELECT 2 plugs. The dimming range spans continuously from 1 to 100%, ensuring precise and smooth light level control. The Constant Light Output (CLO) function compensates for the natural lumen depreciation of LEDs over time, maintaining consistent illumination throughout the system's lifetime. The fade2zero feature enables gradual, controlled switch-off, while power-up fading at AC prevents sudden light variations at startup. The Service Monitor logs relevant operational events, supporting predictive maintenance routines. Integrated protective features against overtemperature, short-circuit, overload, no-load operation and input voltage variations are complemented by the Intelligent Voltage Guard, which continuously monitors overvoltage and undervoltage conditions. An efficiency of up to 90% and a stand-by power input of less than 0.2 W deliver significant energy savings, while a nominal lifetime of 100,000 hours ensures long-term reliability. The driver is also suitable for emergency escape lighting systems in accordance with EN 50172, extending its applicability across professional and commercial environments.
