OSRAM – New range of 24V DALI LED drivers for tunable white lighting applications


OSRAM has introduced a series of 24V DALI drivers which offers a constant-voltage output for use in tunable white lighting applications.

The OTi DALI drivers produce flicker-free light. They have a particularly small cross-section of only 32mm x 22mm, and support dimming down to 0.1%.

These LED DALI drivers can be used with various control devices, including the OSRAM tunable white rotary dimmer, the DALI MCU TW, or the latest OSRAM DALI Professional systems. The drivers are also compatible with building-automation solutions from well-known manufacturers.

OTi DALI drivers can be combined with products from the OSRAM LINEARlight Flex TW family to create a perfectly matched lighting system. In combination with the LED Flex modules, they are also suitable as drivers offering individual four-channel control in whitelighting systems based on Red/Green/Blue (RGB) LEDs.
