Information about the MEAN WELL SPWM-240-48DA2Q
The MEAN WELL SPWM-240-48DA2Q is a premium 240W LED driver optimized for 48V systems requiring advanced Tunable White, RGB, or RGBW color control. By utilizing the latest DALI-2 DT8 protocol, this driver allows for the sophisticated management of four independent output channels through a single DALI address, significantly simplifying professional lighting installations. A standout characteristic is the fixed 3.2 kHz PWM output frequency, which ensures a completely flicker-free lighting experience in full compliance with the CE ErP directive, making it ideal for high-end residential and commercial environments. The unit features an ultra-slim linear housing with a height of only 28.5 mm, allowing it to be easily concealed within narrow architectural profiles, furniture, or cove lighting applications. In addition to DALI control, the integrated PUSH dimming interface provides a flexible alternative for manual control of brightness and color temperature via standard momentary switches. With a high efficiency rating of 93% and a fanless design for silent operation, this driver is engineered for maximum reliability, offering a typical life expectancy of 50,000 hours and a comprehensive five-year manufacturer warranty.
