LED power supply Tridonic with adjustable output current
This LED power supply is dedicated to professional linear and area luminaires. Constant current operation and a wide operating window ensure high compatibility with many LED modules. Output current is adjustable from 250 to 400 mA using the I-SELECT 2 interface in 1 mA steps. This allows precise matching of the module requirements and maximises system efficiency.
High efficiency up to 91% reduces power losses and internal heating. The slim low profile ML300 housing fits narrow trunking systems and compact linear luminaires. The unit is suitable for use in protection class I and class II luminaires, which gives flexibility in project design.
LED power supply with DALI, DSI and switchDIM control
The LED power supply integrates the one4all interface supporting DALI-2 DT 6, DSI, switchDIM and corridorFUNCTION V2. This enables comfortable dimming in the 10–100% range and easy integration into modern lighting control systems. The dimming curve is optimised for the human eye, while amplitude dimming technology ensures flicker free light output.
The switchDIM function allows direct control using a standard pushbutton. A short press switches the power supply on or off. Holding the button dims the light level up or down. The corridorFUNCTION is ideal for staircases, corridors and circulation areas that need presence based lighting and energy savings.
LED power supply for emergency lighting and demanding projects
The LED power supply is suitable for emergency lighting systems in accordance with EN 50172 and EN 60598-2-22. It can operate on DC or pulsed DC from central battery systems. In DC mode it maintains about 95% of the nominal light level when used within the specified operating window.
Comprehensive protection features increase reliability in demanding installations. The unit protects against short-circuit, overload, overtemperature and improper mains conditions. Surge immunity up to 2 kV versus earth helps the power supply withstand mains transients. Lifetime up to 100,000 hours and a five year manufacturer warranty make this Tridonic LED power supply a solid, long term choice for commercial and industrial lighting projects.
