Product description Tridonic LC 25W 50–350mA power supply
The Tridonic LC 25W 50–350mA 230V o4a NF h16 EXC4 led power supply is designed for professional office and linear luminaires. It operates as a constant current power supply with adjustable output from 50 to 350 mA, which allows precise matching to many LED modules. High efficiency up to 91.1% reduces energy losses and helps limit thermal stress in the luminaire.
This model belongs to the excite NFC series and supports near field communication. NFC programming with companionSUITE enables fast and repeatable configuration, ideal for production and large projects. Parameters can also be set via DALI, so the power supply integrates easily into advanced lighting control systems. Functions such as eCLO, fade2zero, power-up fading and a lifetime indicator improve comfort and system reliability.
The compact 16 mm high metal housing allows installation in narrow profiles, recessed channels and slim office luminaires. IP20 protection rating makes the power supply suitable for indoor applications in dry environments. Very low stand-by consumption below 0.14 W meets strict energy efficiency requirements. Comprehensive protection against overtemperature, short-circuit, overload and no-load operation safeguards the connected LED modules.
LED power supply with DALI-2, NFC and wide dimming range
The led power supply fully supports the DALI-2 standard including parts 251, 252 and 253. It can store luminaire data, report energy usage and deliver diagnostic information for maintenance planning. Besides DALI-2, the unit also supports DSI and switchDIM control, which allows direct connection of a push button for switching and dimming. The corridorFUNCTION makes it easy to create presence-based lighting profiles in corridors and shared spaces.
Dimming from 1 to 100% is realized by amplitude dimming, providing stable and flicker-free light output. The adjustable minimum and maximum dimming levels help tailor the behaviour to application needs. NFC multiprogramming enables batch configuration of many devices in one carton, saving installation time and reducing errors. Intelligent voltage guard, constant light output and diagnostic features support predictive maintenance strategies.
LED power supply Tridonic LC 25W for office and linear applications
The Tridonic LC 25W 50–350mA led power supply is an excellent choice for office, corridor, linear and area luminaires. Wide AC and DC input voltage ranges ensure reliable operation, also in central battery and emergency systems according to relevant standards. Push terminals simplify wiring and reduce installation time for contractors and OEMs. With a nominal lifetime up to 100,000 hours and a five-year warranty, this power supply delivers long term reliability and low total cost of ownership for demanding lighting projects.
