Frequently Asked Questions

Can I use the PWM-120-12KN to control 12V LED lighting directly from a KNX building automation system?

Yes. The PWM-120-12KN has a built-in KNX interface, allowing direct integration into KNX building automation networks without requiring a separate KNX-DALI gateway. It outputs 12V at 10A (120W) with a constant voltage PWM-style output compatible with 12V LED strips.

Is the PWM-120-12KN suitable for outdoor or covered wet-area LED lighting installations?

Yes. The IP67 rating makes the PWM-120-12KN suitable for outdoor enclosures and covered locations exposed to rain or moisture. Its -40°C to +90°C operating temperature range also covers demanding outdoor climates.

How many meters of 12V LED strip can the PWM-120-12KN drive?

The PWM-120-12KN supplies up to 120W at 12V. For a 10W/m LED strip that is approximately 12 meters (120 ÷ 10); for a 14.4W/m strip, approximately 8.3 meters (120 ÷ 14.4). Confirm your strip's rated power per meter and apply a 20% derating buffer.

Does the PWM-120-12KN require an external gateway to work on a KNX network?

No. The KNX interface is built into the driver, so no external KNX-DALI gateway is needed. This simplifies panel wiring and reduces the number of components in KNX lighting control installations.

Can the PWM-120-12KN be used for 12V LED strip lighting in a hotel corridor managed by a KNX system?

Yes. The PWM-120-12KN is designed for this type of application, providing 120W of 12V constant voltage output with direct KNX control. Smooth PWM-style dimming is compatible with 12V LED strip lighting commonly used in hospitality corridor and accent lighting.

How does the PWM-120-12KN's standby power compare to the standard PWM-120-12?

The PWM-120-12KN specifies a standby power consumption of less than 0.5W, which is beneficial in large building installations where many drivers may be in standby. The standard PWM-120-12 does not publish this standby figure; it uses a 3-in-1 dimming interface rather than KNX.
