Mean Well PWM-120-36DA Power Supply 120W 36V - DALI

Yes. The PWM-120-36DA is equipped with a DALI interface, allowing it to be addressed and controlled by any DALI-compatible building management or lighting control system. This makes it suitable for commercial installations where centralised dimming control is required.

Yes. The IP67 waterproof rating means the driver is protected against dust ingress and temporary submersion, making it suitable for outdoor signage, facade lighting, and covered wet areas. Its operating range spans -40°C to +90°C.

With a maximum output of 120W at 36V and 3.4A, the PWM-120-36DA can power a strip run calculated by dividing 120W by the strip's watt-per-meter rating — for instance, a 12 W/m strip allows up to 10 m. Check your specific strip's rated power per meter.

Yes. The DALI interface lets this 120W, 36V driver integrate directly into DALI-based control systems used in commercial cove and accent lighting. The PWM-style output delivers smooth, flicker-free dimming on 36V LED strips installed in cove or recessed channels.

Yes. Retail environments often use DALI for zone-by-zone scene control, and the PWM-120-36DA's DALI interface supports individual device addressing within a DALI loop. At 120W and 36V it can handle medium-sized display lighting loads.

The PWM-120-36DA receives its DALI control signal from the DALI bus in your installation; the DALI bus itself requires a separate small DALI power supply (typically provided by the DALI controller or a dedicated bus supply). The driver's load output is the 36V DC supply to your LEDs.

Both share the same 120W, 36V, 3.4A output and IP67 rating. The key difference is the dimming interface: PWM-120-36 uses built-in 3-in-1 dimming (PWM, 0–10V, resistance), while PWM-120-36DA uses a DALI interface for integration into DALI addressable lighting systems.
