Frequently Asked Questions

Can I use the PWM-90-12DA2 with a DALI2 smart lighting controller?

Yes. The PWM-90-12DA2 implements the DALI2 protocol, which is the updated standard offering enhanced device query and reporting capabilities compared to original DALI. It is compatible with DALI2-compliant controllers and backward-compatible with many DALI systems.

Is the PWM-90-12DA2 suitable for outdoor LED signage exposed to rain?

Yes. With an IP67 waterproof rating, this driver is protected against dust ingress and temporary water immersion. It is appropriate for outdoor LED signage and illuminated outdoor displays as long as the enclosure is not permanently submerged.

How much 12V LED strip lighting can the PWM-90-12DA2 support?

The driver provides 90W at 12V (7.5A maximum output). A strip rated at 7.2W per meter, for example, would allow approximately 12.5 meters (90W ÷ 7.2W/m ≈ 12.5m). Always verify your strip's rated power per meter and limit continuous load to 80% of rated capacity (72W) for long-term reliability.

Can the PWM-90-12DA2 power 12V LED strips in a museum or gallery accent lighting system?

Yes. Its DALI2 dimming capability allows precise, flicker-free brightness control suited to gallery and museum accent lighting. At 90W and 12V, it can drive a meaningful run of 12V strip, and the IP67 housing allows flexible placement within the installation space.

What is the input voltage range of the PWM-90-12DA2 and does it support low-voltage DC input?

The PWM-90-12DA2 accepts 12–305VAC input, which is a notably wide range that includes very low AC voltages. This is distinct from many other PWM-90 models that start at 90VAC, making this model suitable for non-standard or low-mains-voltage environments.

How does the PWM-90-12DA2 differ from the PWM-90-12DA?

Both are 90W, 12V, 7.5A IP67 drivers, but the PWM-90-12DA uses the original DALI protocol while the PWM-90-12DA2 uses the newer DALI2 standard. DALI2 adds enhanced device interoperability and diagnostics. The DA2 model also has a lower minimum input voltage (12VAC vs. 90VAC). Dimensions and certifications are identical.
