The dimmable constant current LED driver (SELV) is an independent power supply unit developed to ensure reliable performance for small-scale lighting installations requiring smooth dimming and compact design. It supports both leading-edge and trailing-edge phase dimmers, with trailing-edge control offering the advantage of quieter operation and reduced electrical noise. The driver maintains a dimming range between 5 and 100 percent, depending on the connected dimmer, enabling precise light level adjustment for diverse lighting environments. With a maximum output power of 6.3 watts and an output current of 150 mA, it is an optimal choice for low-power LED luminaires such as decorative fixtures and compact downlights. The driver is suitable for luminaires marked with F, M, or MM symbols according to EN 60598, VDE 0710, and VDE 0711 standards, ensuring compliance and safety in professional lighting installations.
Encased in a white polycarbonate housing, the driver combines durability and low weight with an IP20 protection rating, making it ideal for indoor applications. Its extra-flat form factor allows for effortless integration into confined spaces such as small ceiling cutouts and low ceiling voids. The unit is equipped with push-in terminals and includes two separate strain relief components—one for input cables and one for output cables—each secured with highly robust clamps that enhance mechanical stability during installation.
The driver incorporates multiple protection mechanisms, including overload, short-circuit, and no-load protection, ensuring long-term reliability and safety under a variety of electrical conditions. It also prevents any output current overshoot during mains on/off transitions, thus protecting connected LEDs from sudden electrical stress.
Operating within a rated supply voltage of 220 to 240 volts and an AC voltage range of 198 to 264 volts at 50 or 60 Hz, the driver maintains dependable functionality even in regions with voltage fluctuations. It provides overvoltage protection up to 320 V AC for one hour and has a total harmonic distortion (THD) of less than 20 percent at minimum load and less than 13 percent at full load, ensuring consistent and flicker-free light output. The driver achieves a start time and turn-off time of less than or equal to 0.5 seconds, ensuring instantaneous response when powered on or off, while the hold time during power failure is zero seconds, eliminating residual current draw.
Output performance is characterized by low-frequency current ripple below ±3 percent, guaranteeing stable light quality with minimal flicker. Both P_ST_LM and SVM values remain within standard limits (≤1 and ≤0.4, respectively), making the driver suitable for environments where visual comfort and compliance with flicker standards are essential. It withstands mains surge voltages of up to 1 kV between line and neutral, 2 kV between line/neutral and protective earth, and 1 kV for mains bursts, along with 2.5 kV surge voltage resistance on the output side against protective earth.
The driver operates reliably in ambient temperatures ranging from -40 to 80 °C, demonstrating resilience in varying installation environments. Its nominal lifetime reaches up to 50,000 hours, providing long-term operational stability and reduced maintenance requirements. Backed by a five-year guarantee, this dimmable constant current LED driver stands as a compact, durable, and technically refined solution for high-quality indoor lighting systems where space constraints and smooth dimming are key priorities.
