Frequently Asked Questions
Does the PWM-90-24DA2 support the DALI2 protocol for smart lighting integration?
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.
Is the PWM-90-24DA2 appropriate for outdoor LED lighting in coastal or high-humidity environments?
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.
How much 24V LED strip can the PWM-90-24DA2 drive?
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.
Can I use the PWM-90-24DA2 to power 24V LED strips in a DALI2-controlled office lighting retrofit?
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.
What is the minimum input voltage for the PWM-90-24DA2 and why does it differ from other PWM-90 models?
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.
Can the PWM-90-24DA2 be used for 24V LED architectural lighting on building exteriors?
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.
