The OPTOTRONIC® 50W indoor linear programmable LED drivers by eldoLED represent a premium class of constant current solutions, developed exclusively for North America to meet the most demanding architectural and commercial lighting requirements. These drivers combine high efficiency, flexibility, and advanced programmability, making them ideal for applications such as linear, indirect, direct, and recessed lighting. Each unit operates within a programmable output current range of 400–1400mA and supports universal input voltages of 120–277V and 347V, providing unmatched compatibility and adaptability across various lighting environments.
Engineered for precision and reliability, the OPTOTRONIC® 50W indoor linear drivers are equipped to dim smoothly down to 1%, ensuring precise light control and superior performance in spaces that demand fine-tuned ambiance. Architectural-grade functions such as Dim to Off, Vaux auxiliary output, and synchronized ON/OFF timing contribute to seamless integration with modern lighting control systems. These intelligent features enable lighting designers and specifiers to implement energy-conscious, visually balanced solutions that maintain aesthetic and operational consistency across installations.
A standout member of this line is the OPTOTRONIC® 50W indoor D4i certified (DALI) LED driver. This model enables bi-directional digital communication between the driver and fixture-integrated components, allowing the exchange of real-time luminaire-specific data. Such functionality supports smart lighting systems, streamlines configuration processes, and contributes to creating truly interoperable luminaires. By adhering to D4i and DALI standards, these drivers provide a foundation for intelligent, connected lighting environments that simplify commissioning, monitoring, and maintenance.
The OPTOTRONIC® programmable dimmable family exemplifies flexibility and precision for OEMs. Through the intuitive OPTOTRONIC programmer, manufacturers can configure output current with 1mA resolution, allowing perfect alignment between driver performance and LED load requirements. Programming is exceptionally convenient—no AC power or live connection is required—ensuring safe and efficient configuration at any stage of production. Users can fully customize key features such as constant lumen maintenance, LED thermal protection, and end-of-life indication, enabling long-term reliability and consistent luminous output throughout the fixture’s lifetime.
Further enhancing its adaptability, the driver’s integrated 0–10V dimming protocol provides specification-grade dimming from true 1% to 10%, accommodating a broad range of lighting control applications. An optional auxiliary output powers low-voltage accessories such as sensors or control modules at 12V, 20V, or 24V, extending the driver’s versatility for complex control ecosystems. The slim linear housing facilitates easy integration into compact fixture designs while maintaining thermal efficiency and safety compliance through UL Class 2 rated outputs.
With high power factor performance, robust protection features, and compatibility across universal voltage inputs (120–277V and 347V, 50/60Hz), the OPTOTRONIC® 50W linear programmable drivers represent a sophisticated balance of precision control, reliability, and ease of use. They empower fixture manufacturers to produce innovative, high-quality luminaires that align with the growing demand for smart, connected, and efficient indoor lighting solutions.
