LED drivers with DALI power supply

The new PRE drivers pack state-of-the-art technology and all the functions of the premium portfolio into the smallest of spaces. The reduced low-profile housings have the same length and width as before (360 mm x 30 mm) but are now only 11 or 16 mm high instead of 21 mm. They offer virtually flicker-free dimming (<5 %) of the connected luminaires from 100 to 1 percent and are equipped with smart interfaces such as NFC (Near Field Communication) and integrated po4a DALI power supply. The combination of NFC and the companionSUITE software package enables the drivers to be quickly and wirelessly programmed during the production process at luminaire manufacturers. Complete packaging units of up to 10 items can be wirelessly configured in a single pass via an antenna. The po4a interface (extended one4all Interface) supplies sensors with power and thus simplifies implementation of sensor-controlled lighting solutions. Additional DALI lines for the sensor are no longer necessary.
 

Flexible setting options

Typical applications for the slim drivers in low-profile housings are linear and area lighting systems in the office environment. They are also suitable for safety lighting in accordance with EN 50172. Common to all the drivers are application-optimised operating windows for maximum compatibility, high energy savings thanks to low stand-by losses (<0.15 W) and high efficiency (>92 %). The drivers are available in both heights with outputs of 50 and 75 W, in each case with adjustable output currents of 100 to 400 mA. There are four options for adjusting the output current: wirelessly via NFC using the web-based Tridonic companionSUITE software, via DALI using masterCONFIGURATOR, with the appropriate I SELECT 2 plug resistor or via the ready2mains programmer.
The manufacturer specifies a nominal life of 100,000 hours and offers a five-year guarantee.
