Frequently Asked Questions
Can the PWM-120-24DA be integrated into a DALI building management system for 24V LED lighting?
Yes. The PWM-120-24DA includes a DALI interface, enabling it to be addressed, grouped, and dimmed by any DALI-compliant building management or lighting control system. It outputs 24V at 5A (120W) with a PWM-style waveform compatible with 24V LED strips.
Is the PWM-120-24DA suitable for outdoor or wet-area LED strip lighting installations?
Yes. Its IP67 rating provides full dust protection and resistance to temporary water immersion, making it appropriate for outdoor enclosures and wet indoor applications. The -40°C to +90°C operating range covers extreme outdoor temperatures.
How many meters of 24V LED strip can the PWM-120-24DA support?
The PWM-120-24DA outputs 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 verify your strip's rated power per meter and apply a 20% derating margin.
Can the PWM-120-24DA be used for DALI-controlled 24V LED strips in a hotel lobby or conference room?
Yes. The DALI interface supports scene-based dimming and group control, making it well suited for hospitality and commercial spaces where multiple lighting zones need to be managed from a central DALI controller. The 120W, 24V output can drive the 24V LED strips typical of these environments.
Does the PWM-120-24DA support operation in outdoor installations during winter in cold climates?
Yes. With an operating temperature starting at -40°C, the PWM-120-24DA is rated for harsh winter climates. The IP67 enclosure also provides protection from rain, sleet, and temporary submersion.
How does the PWM-120-24DA compare to the PWM-120-24 and PWM-120-24DA2?
All three deliver 120W at 24V/5A with IP67 protection. The PWM-120-24 uses 3-in-1 dimming (PWM, 0-10V, resistance). The PWM-120-24DA uses the original DALI interface for integration into DALI lighting networks. The PWM-120-24DA2 upgrades to DALI2, adding bidirectional communication and enhanced device-type support.
