Frequently Asked Questions

Can the PWM-120-48DA be controlled by a DALI building automation system?

Yes. The PWM-120-48DA has a DALI interface that allows it to be individually addressed and dimmed by any IEC 62386-compliant DALI controller or building management system. This makes it a standard choice for commercial 48V LED installations requiring centralised control.

Is the PWM-120-48DA waterproof enough for outdoor use?

Yes. The IP67 rating certifies protection against dust and temporary submersion up to 1 metre, making it suitable for outdoor signage cabinets, building facade lighting, and covered wet-area installations. Operating temperature range is -40°C to +90°C.

How many meters of 48V LED strip can the PWM-120-48DA power?

The driver supplies up to 120W at 48V and 2.5A. To find the maximum strip length, divide 120W by the strip's rated watt-per-meter figure — a 15 W/m strip, for example, allows up to 8 m. Confirm your strip's rated power per meter before planning the run.

Is the PWM-120-48DA suitable for DALI-controlled museum or gallery display lighting at 48V?

Yes. Museum and gallery lighting often requires precise, programmable dimming scenes, which DALI supports natively. The PWM-120-48DA's DALI interface integrates into such systems, and the PWM-style output produces smooth, artifact-free dimming on 48V LED strips.

Can I use the PWM-120-48DA in a DALI Zone controlling multiple fixtures?

Yes. DALI allows up to 64 individually addressed devices per bus, and the PWM-120-48DA is DALI-addressable. Multiple drivers can operate in the same DALI zone while responding to individual addressing or group commands from the controller.

What is the key difference between the PWM-120-48DA and PWM-120-48?

Both are 120W, 48V, 2.5A drivers with IP67 rating and identical physical dimensions. The PWM-120-48 uses built-in 3-in-1 dimming (PWM signal, 0–10V, resistance); the PWM-120-48DA replaces that with a DALI interface for addressable DALI network integration.
