The EM powerLED 45 W LED Drivers in PRO DIM and SELV versions combine normal and emergency lighting modes for LED luminaires in one unit. The compact housings of the installation version save space in the luminaire and the modest space requirements of these combination devices will provide greater freedom for luminaire designers.

The combination LED Drivers provide an output of 45W in normal operation, and the integrated battery system produces up to 4W of emergency lighting power. In normal operation EM powerLED PRO DIM 45W can be dimmed via DALI, switchDIM or the corridorFUNCTION and is prepared for ready2mains. Emergency light functionality is monitored centrally via DALI. One DALI address is sufficient for performing lighting control, dimming and the prescribed emergency lighting tests and for documenting this centrally; for example via connecDIM or the x/e touch panel. The devices are compatible with the EXCITE series of LED Drivers from Tridonic and can be easily integrated in any installation.

EM powerLED ST FX 45W 50V with SELV qualification is a version with fixed output and integrated self-test function. In normal operation this LED Driver provides the dimming function via the simple corridorFUNCTION and does not require a higher-ranking DALI system.

The weekly function tests prescribed for emergency lighting and the annual service life test are performed via the integrated automatic self-test function and a two-colour LED status display indicates the test results.

There are two housing versions available: a built-in version that saves on space in the luminaire and the Strain Relief (SR) version which supports a wide range of LED modules with external LED Drivers and which is immediately ready for operation together with plug-in remote batteries.
