This constant current LED driver is a compact, high-quality power solution developed for reliable operation in a wide range of linear and area lighting applications, including offices, educational institutions, healthcare facilities, and general commercial environments. It supports dimming through a 0–10 V interface, allowing full control of light output across a 1–100% range, including standby functionality for further energy reduction. The driver meets UL8750 requirements with a Class 2 output based on UL1310, is UL Listed as Class P, and complies with FCC Part 15 Class A standards, ensuring compatibility with North American safety and electromagnetic performance regulations.
The device allows flexible current configuration, with output current adjustable between 100 and 1,050 mA using Near Field Communication (NFC) technology, enabling one driver to serve multiple LED modules or system setups. It delivers a maximum output power of 35 W and achieves typical efficiency up to 85.7%, maintaining stable operation while meeting the industry’s strictest flicker-free performance standards. The driver supports a nominal lifetime of up to 100,000 hours, ensuring long-term reliability in both dry and damp environments.
Constructed with a durable white metal casing, the driver provides an IP20 protection rating suitable for indoor use. It includes a 24 V auxiliary output for control gear or sensor integration and supports programmable fade-off timing for smooth dimming transitions. The internal protection system safeguards against overtemperature, short-circuit, overload, no-load, and input voltage anomalies. Users can configure the device via NFC for customized performance, including selecting between linear, logarithmic, or square dimming curves to achieve desired visual comfort. The unit’s operating window allows maximum compatibility with a broad range of LED modules and control systems, while compliance with California Title 24 regulations ensures energy code alignment for modern building standards.
Operationally, the driver supports a rated supply voltage range of 120–277 V AC and operates reliably within an input range of 108–305 V AC at both 50 and 60 Hz. Typical current draw is 152 mA at 277 V and 350 mA at 120 V under full load. Leakage current remains below 0.75 mA in all conditions, ensuring electrical safety. The device exhibits low in-rush current behavior—7 A at 277 V and 2 A at 120 V—helping prevent circuit overload during power-up. Maximum input power consumption reaches 40.1 W at 277 V and 40.4 W at 120 V, with standby power consumption kept below 0.5 W. No-load power consumption is exceptionally low, measured at approximately 1 W at 277 V and 0.5 W at 120 V.
The driver’s electrical performance includes a power factor of 0.95 at 277 V and 0.99 at 120 V, maintaining low total harmonic distortion (THD) below 10% across all input conditions. Startup time is under 0.5 seconds, ensuring rapid light activation, while power failure hold time remains below 0.02 seconds to prevent flicker during brief voltage interruptions. The output current tolerance is within ±5%, and output low-frequency ripple stays below ±5%, ensuring consistent light quality. The maximum output voltage (U-OUT) is limited to 60 V, suitable for Class 2 circuits.
For reliability, the driver incorporates robust surge protection—rated at 2 kV between line and neutral and 2.5 kV between line/neutral and protective earth—with an additional 0.5 kV surge tolerance on the output side. Its compact dimensions of 280 mm in length, 30 mm in width, and 21 mm in height allow easy integration into various fixture types. The driver is supported by a 5-year manufacturer guarantee and is built to deliver dependable performance throughout its service life of up to 100,000 hours.
Overall, this constant current LED driver offers an optimal balance of functionality, control, and longevity. Its precise dimming control, NFC configurability, comprehensive protection suite, and compliance with major safety and performance standards make it an ideal solution for high-quality, flicker-free lighting systems across commercial and institutional environments.
