The fixed output DC-String constant voltage built-in LED driver provides reliable and efficient operation for a wide range of DC-String lighting applications. With compatibility across other DC-String components, this driver supports a maximum output power of 100 W while achieving up to 94% efficiency, ensuring optimal energy utilization. Certified to FCC 15 Class A and B standards, it delivers electromagnetic compatibility suitable for commercial and residential environments. The driver has a nominal lifetime of up to 50,000 hours, making it a durable choice for long-term installations.
Housed in a low-profile metal casing with a white cover, the driver offers IP20 protection and is suitable for dry and damp locations. Its compact design allows for seamless integration into various luminaire assemblies without compromising aesthetics or space. The driver incorporates intelligent protective features, including an Intelligent Temperature Guard that provides overtemperature protection, as well as short-circuit and overload safeguards, ensuring safe operation under varying electrical conditions.
The driver operates within a wide supply voltage range of 120 – 277 V AC, with an AC voltage tolerance of 108 – 305 V, and a mains frequency of 50 / 60 Hz. At full load, the typical input current measures 383 mA at 277 V and 886 mA at 120 V, while leakage currents remain below 0.5 mA. During no-load operation, the typical input current is 48.4 mA at 277 V and 34.8 mA at 120 V, with input power of 2.3 W and 2.6 W respectively. Full-load efficiency reaches 93.6% at 277 V and 91% at 120 V, with total harmonic distortion below 15% at 277 V and under 10% at 120 V. The output voltage maintains tight tolerances of -2.1% to +8.4%, and the low-frequency output current ripple remains within ±1%, ensuring stable and consistent performance.
For installation flexibility, the driver supports variable secondary cable lengths as specified in the data sheet, while electrical safety is reinforced with surge capabilities of 1 kV between L-N and 2 kV between L/N and PE, with output-side surge protection of 2 kV. Backed by a five-year guarantee, this DC-String constant voltage LED driver combines reliability, safety, and efficiency in a compact, robust package suitable for diverse lighting systems.
