Frequently Asked Questions

Can the PWM-120-24DA2 be used in a DALI2 smart lighting system controlling 24V LED strips?

Yes. The PWM-120-24DA2 implements the DALI2 standard, offering bidirectional communication and enhanced device-type features for integration into modern DALI2 smart lighting systems. It outputs 24V at 5A (120W) with a PWM-style output suited to 24V LED strips.

Is the PWM-120-24DA2 suitable for outdoor LED lighting applications?

Yes. The IP67 rating provides full dust ingress protection and resistance to temporary water immersion, making it suitable for outdoor enclosures and covered wet-area installations. The operating range of -40°C to +90°C covers a wide range of outdoor climates.

How many meters of 24V LED strip can the PWM-120-24DA2 power?

With a 120W output at 24V, the achievable strip length depends on the strip's power per meter. A 24W/m strip supports up to 5 meters (120 ÷ 24); a 14.4W/m strip supports approximately 8.3 meters (120 ÷ 14.4). Confirm your strip's rated power and apply a 20% derating buffer for reliable operation.

Can the PWM-120-24DA2 be used for 24V LED cove or indirect lighting in a commercial office under DALI2 control?

Yes. The DALI2 interface provides precise, addressable dimming control appropriate for commercial office lighting. The 120W, 24V PWM-style output is compatible with 24V LED strips used in cove and indirect lighting installations.

What advantage does DALI2 provide over DALI in the PWM-120-24DA2 for lighting control projects?

DALI2 introduces standardized device types, backward compatibility with DALI, and bidirectional communication that allows the controller to query device status. In the PWM-120-24DA2, this means more reliable commissioning, better interoperability with DALI2 controllers, and the ability to report operating status back to the lighting management system.

Can the PWM-120-24DA2 be installed in a sealed outdoor enclosure for landscape lighting?

Yes. The Class II design requires no functional ground connection, and the IP67 rating allows installation in sealed outdoor enclosures exposed to rain and temporary submersion. The wide operating temperature range of -40°C to +90°C ensures reliable performance in outdoor landscape conditions.
