Increased operating window 4 easier decisions

Generation 4

The more applications a driver can cover, the easier it is always to have the right product in stock.

What’s needed is an operating window of appropriate size. Tridonic goes one step further however. The operating windows overlap from one driver to the next. This results in maximum flexibility and covers all the operating points within the voltage range. It is then possible to maintain reduced stock levels and still be able to choose a driver that is not only suitable but also more efficient. And because the new Generation 4 drivers are backwards compatible, luminaires can easily be updated with state-of-the-art technology.

Tridonic Generation 4



The larger overlapping operating windows of the fourth generation enable both dimmable and non-dimmable drivers to be used in a wide range of applications.

Tridonic Generation 4



Simple. Flexible. And packed with possibilities.

Generation 4 kicks off with the linear Low-Profile LED drivers in the excite category (EXC4) which are used for linear luminaires such as pendant and recessed ceiling luminaires. With its dimmable and non-dimmable versions, the fourth generation of excite drivers (EXC4) covers a wide variety of lighting requirements perfectly – everything from simple to sophisticated. In addition to optimised operating windows for a wide range of applications, both driver versions feature an NFC interface that allows individual adjustment of the output current as well as extremely simple configuration and time-saving multi-programming via companionSUITE. Thanks to lumDATA, the dimmable drivers also comply with the latest DALI-2 specifications for storing and sharing essential data.
