The OPTOTRONIC 190W two-channel constant current linear LED drivers are powerful, programmable solutions ideally suited for industrial, hazardous, and outdoor applications. These models are commonly used in mid-bay and high-bay luminaires, roadway and parking garage lighting, and fixtures operating in challenging environments. Each driver combines the strength of two 95W drivers into a single streamlined 190W configuration, maximizing performance and reducing system complexity. The drivers offer precise dimming control down to 1% and support analog 0–10V dimming interfaces, making them compatible with standard dimmers, energy management systems, and sensors. They also include an auxiliary DC power output for external sensor integration, supporting advanced control and automation functions.
The OPTOTRONIC 190W drivers are available in both standard (120–277V) and high-voltage (277–480V) versions, providing flexibility for various industrial and infrastructure installations. Each channel supports output currents between 700 and 2750 milliamps, enabling precise configuration for different LED loads and fixture designs. Housed within an IP66-rated enclosure, these drivers are built for durability in outdoor and industrial environments, ensuring protection against dust, moisture, and environmental stress. Programming is easily achieved using the OT Programmer, allowing manufacturers to configure parameters without connecting to an AC power source. The entire system is UL Class P listed and UL Damp Rated, confirming safety and reliability in demanding conditions.
The OPTOTRONIC programmable dimmable driver family is engineered to deliver exceptional flexibility and efficiency for outdoor and architectural lighting applications. Through one-click programming via the OT Programmer, OEMs can fine-tune output currents with 1mA precision to optimize LED performance. The built-in AstroDIM function provides autonomous night-time dimming based on an internal clock that can be configured for up to a full year, enhancing energy savings and fixture longevity. These drivers support multiple control protocols, including 0–10V, DALI, and D4i, with the 95W and 190W models offering 1% minimum dimming for refined light control.
Additional integrated features such as constant lumen maintenance, LED thermal protection, and an auxiliary output further enhance the adaptability and reliability of these drivers. D4i-certified versions enable two-way communication between the driver and luminaire components, offering diagnostic feedback and luminaire-specific data to centralized management systems. Built-in surge protection up to 6kV and EFT protection up to 4kV safeguard both the driver and the connected LEDs from transient electrical events, ensuring consistent performance in industrial and outdoor settings.
The OPTOTRONIC family is available across multiple input voltage configurations, including 120–277VAC, 347–480VAC, and 277–480VAC (specific to the 190W models), enabling compatibility with a wide range of electrical infrastructures. Thermal management is a key strength, with a maximum case temperature of 85°C (185°F) for the 190W models, ensuring stable operation and long lifespan. The drivers maintain full performance within ambient operating temperatures ranging from -40°C to 55°C (-40°F to 131°F), allowing deployment in both extreme cold and heat without compromising functionality.
Versatile in application, the OPTOTRONIC 190W linear drivers are suitable for a wide range of lighting designs including architectural building-mounted fixtures, bollards, cobra heads, decorative landscape luminaires, high-mast installations, industrial high bays, mini wall packs, roadway systems, and shoebox-style area lights. Exclusively available in North America, the OPTOTRONIC 190W two-channel drivers represent a robust, intelligent, and efficient solution for next-generation lighting systems requiring high power, configurability, and long-term reliability.
