Information about the MEAN WELL PWM-60-24DA
The MEAN WELL PWM‑60‑24DA is a 60 W constant‑voltage LED driver with 24 V DC output and PWM‑style regulation, tailored for medium‑voltage LED strips and 24 V LED modules in DALI‑ or DALI‑2‑based lighting systems. Its PWM output helps maintain consistent brightness and colour appearance along longer runs of 24 V strips, even when they are dimmed down to low levels.
This model’s strengths include its solid typical efficiency around 89 %, the wide 90–305 V AC input range with active power factor correction, and the fully potted IP67 enclosure that supports use in dry, damp and wet locations. The wide case temperature range from −40 °C to +85 °C, together with robust protection features (short‑circuit, overload, overvoltage, overtemperature), makes the PWM‑60‑24DA a reliable option for both indoor and outdoor architectural, commercial and industrial lighting projects.
A distinctive characteristic of the PWM‑60‑24DA is its native DALI / DALI‑2 support (device type DT6), which enables precise, addressable dimming and grouping in modern building management and lighting control systems. Combined with its long MTBF, comprehensive safety and EMC certifications, and constant‑voltage PWM behaviour optimised for 24 V LED strips, this driver is well suited for cove lighting, linear accent lighting, signage and other 24 V LED applications where stable dimming and centralised DALI control are key requirements.
