The 50W programmable constant current LED driver is a versatile solution developed for high-performance outdoor and industrial lighting applications where precision control, durability, and flexibility are essential. It supports smooth, flicker-safe dimming to 10% using a 0–10V analog control protocol and includes an optional auxiliary power output for integrated control devices and sensors. The driver operates on a wide input voltage range of 120–277V (UNV) or 347–480V (HV), making it compatible with a broad range of installation environments. With programmable output currents ranging from 175mA to 2100mA, it enables fixture designers to optimize luminaires across diverse mounting heights and applications including bollards, wall packs, post-tops, pathway lighting, and low-bay industrial luminaires.
Built with robust surge protection and superior power quality, this driver provides 6kV common and differential mode protection and 4kV EFT protection for industrial-grade reliability. Its logarithmic dimming curve ensures a natural and consistent visual experience that complies with NEMA 77 flicker safety standards. The inclusion of an optional AUX power output—selectable at 12V, 20V, or 24V—eliminates the need for external power packs, simplifying integration with sensors, wireless controllers, and other connected devices. The driver also supports an “electronic dim-to-off” function, which allows lighting systems to meet energy code requirements and achieve deeper power savings during off-hours.
Encased in an IP66-rated, F-CAN form factor housing, the driver is engineered for outdoor resilience, maintaining reliable performance across an operating temperature range from -40°C to 55°C. Its compact design and rugged enclosure ensure protection from dust, moisture, and harsh weather conditions. The programming process is streamlined using the OT Programmer, allowing fixture manufacturers to configure output current settings with 1mA precision—without the need to power up or connect the driver to line voltage. This ease of programming makes the driver ideal for high-volume production and customized luminaire design workflows.
Part of a broader family of programmable dimmable LED drivers, this model shares the same intelligent control ecosystem that supports advanced lighting management and communication. The family includes options for 0–10V, DALI, and D4i control protocols, with dimming down to 10% across most models and down to 1% for select 95W and 190W versions. With integrated features such as AstroDIM, constant lumen maintenance, LED thermal protection, and auxiliary power output, these drivers empower OEMs to build connected and adaptable lighting systems. AstroDIM, in particular, provides autonomous night-time dimming based on an internal yearly programmable timer, enabling energy reduction without requiring an external control system.
In addition to flexible programming, the driver delivers exceptional resilience against electrical disturbances with up to 6kV transient protection for outdoor use and 4kV EFT protection for industrial settings. Available in universal input voltages (120–277VAC) and high-voltage configurations (347–480VAC), it meets a wide range of global standards. It is UL Class P listed, UL Damp Rated, and IP66 certified, ensuring long-term reliability and compliance in both architectural and commercial environments.
Common application areas include architectural building mounts, bollards, cobra heads, decorative landscape fixtures, high masts, industrial high bays, mini wall packs, roadway luminaires, and shoebox-style area lights. Its combination of programmability, protection, and communication readiness makes it a future-proof solution for OEMs developing smart, efficient, and connected outdoor lighting systems across North America.
