This constant current LED driver combines precise dimming, robust protection, and extended operational life for demanding indoor applications. It operates with a 0 … 10 V interface including stand-by, offering a dimming range from 1 to 100% to suit various lighting scenarios. UL8750 compliance with class 2 output based on UL1310, UL Listed Class P certification, and FCC Part 15 Class A approval ensure adherence to strict North American safety and performance standards. The output current is adjustable via NFC between 150 and 1,400 mA, providing maximum flexibility, while the driver supports a maximum output power of 50 W and efficiency up to 86.7%. It meets the strictest flicker-free performance standards, making it suitable for sensitive environments, and carries a nominal lifetime of up to 100,000 hours.
The housing is constructed from white metal, providing durability and reliability for both dry and damp locations. Protection features include overtemperature, short-circuit, overload, no-load, and input voltage range safeguards. Additional functions include adjustable output current in 1-mA steps via NFC, a 24 V auxiliary output, and programmable fade-off time. The driver allows tailoring of dimming responses with Linear, Logarithmic, or Square dimming curves, offering maximum compatibility and configurability. Compliance with California Title 24 ensures suitability for energy regulations and code requirements, while the operating window supports widespread application across linear and area lighting projects.
Typical applications include office, education, healthcare, and general lighting environments where consistent LED performance and flicker-free operation are critical. The rated supply voltage spans 120 – 277 V AC with a voltage range of 108 – 305 V and a mains frequency of 50 / 60 Hz. Input currents at full load are 217 mA at 277 V and 488 mA at 120 V, with typical no-load input currents of 30 mA and 16 mA, respectively. Leakage current remains below 0.75 mA under full load conditions. Inrush current peaks at 15 A / 19 µs for 277 V and 4 A / 27 µs for 120 V, while maximum input power reaches 58 W at 277 V and 59.7 W at 120 V. Stand-by consumption is less than 0.5 W, with no-load input power ranging from 1.28 W to 1.44 W depending on voltage.
Efficiency values are 86.7% at 277 V and 84.5% at 120 V, with power factors of 0.95 and 0.99, respectively. Total harmonic distortion remains below 20% at 277 V and 10% at 120 V. Start time is ≤ 0.5 s at both supply voltages, with turn-off times under 0.03 s and hold times during power failure below 0.02 s. Output current tolerance is ±5% with a maximum non-repetitive peak of output current ≤ output current + 5%. Output LF current ripple is ±5%, and output voltage reaches up to 60 V with low flicker, meeting P_ST_LM ≤1 and SVM ≤0.4 standards. The driver supports a dimming range from 1 to 100% and withstands mains surge capabilities of 2 kV between L-N, 2.5 kV between L/N-PE, and a surge voltage at output of 0.5 kV. The IP20 protection rating ensures safety in indoor environments, and the compact form factor measures 360 mm in length, 30 mm in width, and 21 mm in height. Lifetime reaches up to 100,000 hours, backed by a 5-year guarantee.
