Technical data of Tridonic LC 40W 500-1050mA 42V o4a T EXC3 led power supply

Product description

Tridonic LC 40W 500-1050mA 42V o4a T EXC3 is a sophisticated in-track LED power supply designed for direct installation in lighting tracks. It delivers a stable constant current for LED modules with smooth dimming control. The compact housing integrates neatly into professional track lighting systems used in commercial projects.

The power supply is compatible with popular Global Trac Pulse tracks from Nordic Aluminium and OneTrack from Stucchi. It also works with selected Powergear and Unipro 3‑phase systems with DALI bus. This makes upgrades of existing lighting systems very convenient, without replacing the full track infrastructure.

LED power supply for spot and downlight applications

The unit is optimised for retail and hospitality lighting with spotlights and downlights. The 40 W output power supports modern high efficiency LED modules used for accent and general lighting. Class II design helps simplify luminaire construction and insulation requirements.

The broad output current range from 500 to 1,050 mA allows matching many different LED modules. Current can be configured via DALI‑2 or by using I‑SELECT 2 plugs. One power supply can therefore cover several luminaire variants, which reduces inventory and project complexity.

LED power supply with DALI‑2 and smooth dimming

The integrated one4all interface supports DALI‑2, switchDIM and corridorFUNCTION control options. Dimming is based on amplitude modulation, which minimises flicker even at low light levels. This is important in retail areas, offices and hospitality zones where visual comfort matters.

corridorFUNCTION enables presence based lighting control using motion sensors wired on the DALI track. The system can automatically switch between standby and full brightness levels. This helps save energy in corridors, back of house areas and circulation routes.

LED power supply reliability and easy installation

The Tridonic power supply is built for long life in demanding professional environments. The rated lifetime of up to 100,000 hours at 25 °C reduces maintenance needs. A five year manufacturer warranty underlines the high reliability level. Comprehensive protection circuits safeguard both the power supply and the connected LED modules.

Installation into the track is fast thanks to the integrated adapter and push terminals. The operating ambient range from -20 to +35 °C covers most indoor applications. The slim 260 mm housing allows discreet integration next to the luminaire head on the track. This results in a clean visual appearance and flexible system design for modern lighting projects.
