Frequently Asked Questions

Can the PWM-120-24KN control 24V LED lighting directly from a KNX building automation system?

Yes. The PWM-120-24KN has a built-in KNX interface, enabling direct integration with KNX networks for scene-based and zone lighting control without requiring a separate KNX-DALI gateway. It outputs 24V at 5A (120W) with a PWM-style constant voltage output for 24V LED strips.

Is the PWM-120-24KN suitable for outdoor or wet-location LED strip installations?

Yes. Its IP67 rating provides protection against dust and temporary water immersion, making it appropriate for outdoor enclosures and wet indoor locations. The -40°C to +90°C operating range accommodates demanding outdoor environments.

How many meters of 24V LED strip can the PWM-120-24KN drive?

The PWM-120-24KN delivers up to 120W at 24V. For a 20W/m strip, that supports up to 6 meters (120 ÷ 20); for a 14.4W/m strip, approximately 8.3 meters (120 ÷ 14.4). Always check your strip's rated power per meter and maintain a 20% headroom margin.

Can I use the PWM-120-24KN for 24V LED strips in a KNX-controlled commercial building without additional gateways?

Yes. The integrated KNX interface eliminates the need for a separate KNX-DALI gateway, simplifying the installation. Standby power consumption is less than 0.5W, which is relevant in large commercial buildings with many drivers that may idle for extended periods.

Is the PWM-120-24KN appropriate for 24V LED signage in a retail environment controlled by KNX?

Yes. The 120W, 24V output can power 24V LED modules and strips used in illuminated retail signage. The KNX interface allows the signage lighting to be scheduled and dimmed as part of the broader KNX retail environment control system.

How does the PWM-120-24KN differ from the PWM-120-24 for a KNX lighting project?

Both deliver 120W at 24V/5A with IP67 protection. The PWM-120-24 uses built-in 3-in-1 dimming (PWM, 0-10V, resistance) and requires a separate gateway for KNX integration. The PWM-120-24KN has a native KNX interface built in, removing the need for that gateway and reducing the overall component count in a KNX installation.
