OSRAM Tunable White System

Platinum Award
The OSRAM Tunable White (TW) System provides a digitally
controllable lighting solution which helps simulate natural
daylight that reinforces human wellness and productivity. This
digital solution offers the freedom to adjust light preferences for Human Centric Lighting (HCL) applications including educational, commercial office and healthcare settings. The OSRAM Tunable White System consists of an OPTOTRONIC® Tunable White LED Driver, Tunable White Wallstation,PrevaLED® Tunable White Light Engine and optional Control Power Pack.

The OSRAM TW Wallstation provides precise color
temperature and brightness control when used in conjunction
with the OPTOTRONIC Programmable TW LED Driver. The color temperature of the PrevaLED light engine can be adjusted within the range of 2700K to 6500K and between 1-100% light intensity. The wallstation comes with three, preprogrammed scene buttons that can be customized to
control the room’s ambiance. Third party tunable white light
engines can be paired with the OPTOTRONIC TW LED Driver,
offering flexibility to OEMs. Using the OPTOTRONIC Programmer allows users to program custom light engine parameters into the driver.

This tunable white system is compatible with light management
systems capable of communicating via DALI-2 for type 8 devices.

The installation of the OSRAM Tunable White System is
straightforward. The OPTOTRONIC TW LED Driver and PrevaLED TW Light Engine is integrated into the luminaire during the manufacturing process. Contractors simply install the luminaires and OSRAM TW Wallstation into the
application space and run a quick wiring test.
