Information about the MEAN WELL SPWM-75-12DA2Q
The MEAN WELL SPWM-75-12DA2Q is a highly sophisticated 75W LED driver engineered for professional multi-channel lighting solutions requiring Tunable White or RGBW capabilities. Equipped with four output channels and a specialized DALI-2 DT8 (Device Type 8) interface, this driver allows for simplified control of color and color temperature through a single DALI address. Its constant voltage PWM output ensures that light quality remains consistent and free of color shifting across the entire dimming range, even at the ultra-fine 0.1% minimum level. The driver features a flicker-free design that complies with the latest CE ErP lighting regulations, making it an ideal choice for high-end residential spaces, galleries, and health-conscious work environments. The ultra-slim plastic housing with Class II isolation allows for easy installation in tight architectural spaces without the need for a safety ground connection. With active Power Factor Correction (PFC) and high energy efficiency of 90%, it operates with minimal heat dissipation and maximum reliability up to a case temperature of 90°C. This combination of digital precision and robust power delivery makes it a premier component for advanced building automation and interactive lighting design.
