Tunable White and HCL solutions with OSRAM LED drivers the easy way
Optimal LED solutions for Tunable White and HCL applications in offices and industrial facilities – the new OTi DALI D NFC TW L in 35 and 75 W seamlessly combine maximum functionality, excellent lighting quality and versatile usability in proven OSRAM quality.
The new OPTOTRONIC INTELLIGENT OTi DALI D NFC TW L in 35 and 75 W are simply ideal for Tunable White and HCL lighting in office and industrial applications.
Perfectly matched with the PrevaLED Linear TW module (available soon), these two non-isolated drivers provide simple and cost-efficient solutions for appealing Tunable White and HCL lighting. In addition to the DALI DT8 Tunable White functions, they can be operated as 2-channel drivers in DT6 mode (e.g. for direct/indirect lighting). The drivers seamlessly combine excellent lighting quality (low current ripple, AM/PWM dimming selectable, DALI dimmable in the 1…100 % range), high reliability (5-year guarantee, 100,000 operating hours at Tc -10 °C), highly flexible module use (wide operating window) with NFC as well as DALI programming (all TW functions simply programmable via Tuner4TRONIC).
