Mean Well PWM-90-24DA2 Power Supply 90W 24V DALI2

Yes. The PWM-90-24DA2 implements DALI2, the updated standard that adds enhanced device identification, status reporting, and multi-instance support compared to the original DALI protocol. It is suitable for integration into modern DALI2 smart building systems.

Yes. The IP67 waterproof rating protects against dust ingress and temporary water immersion, making it suitable for coastal or high-humidity outdoor environments. The operating range of -40°C to +85°C also covers conditions in warm, humid climates.

With a 90W output at 24V (3.75A), this driver can power 24V LED strip up to 90W total. For example, strip rated at 12W per meter supports 7.5 meters (90W ÷ 12W/m = 7.5m). For continuous duty, derate to 80% capacity (72W) — about 6 meters at that rating. Check your strip's specific rated power per meter.

Yes. The DALI2 interface allows this driver to integrate directly into a DALI2 office lighting control system, supporting scene setting, occupancy-based dimming, and individual zone control. At 90W it can handle a meaningful strip load per zone.

The PWM-90-24DA2 accepts input from 24–305VAC, giving it a lower minimum input voltage than most sibling models that start at 90VAC. This wider low-end range can be useful in installations with non-standard or stepped-down supply voltages.

Yes. The IP67 waterproof rating allows outdoor placement, and the -40°C to +85°C operating range covers year-round exterior conditions. The DALI2 interface supports integration into facade lighting control systems that require addressable, dimmable zones.
