Frequently Asked Questions
What is the DALI interface on the ELG-150-24DA and what systems is it compatible with?
The DA suffix indicates this driver has a DALI (Digital Addressable Lighting Interface) input compliant with IEC 62386. DALI is a two-wire digital bus used in commercial building lighting control systems, allowing each driver on the bus to be individually addressed and dimmed from a DALI controller without additional analog wiring.
Can the ELG-150-24DA be used to retrofit DALI-controlled LED strip lighting in a commercial office?
Yes. The ELG-150-24DA is designed for this use case. It accepts DALI commands to smoothly dim 24V LED strips and can be individually addressed on a shared DALI bus, enabling scene control and occupancy-based dimming as expected in commercial office environments.
Is the ELG-150-24DA suitable for outdoor DALI-controlled signage or facade lighting?
Yes. The IP67 waterproof rating allows the ELG-150-24DA to be placed in outdoor enclosures subject to rain and moisture. Combined with its -40°C to +90°C operating range, it is appropriate for outdoor DALI lighting networks controlling facade strips or illuminated outdoor signs.
How much 24V LED strip can the ELG-150-24DA support?
The driver delivers up to 150W at 24V (6.25A maximum). For a 9.6 W/m strip, that supports approximately 15.6 m (150 ÷ 9.6). For a 20 W/m high-output strip, about 7.5 m (150 ÷ 20). Confirm your strip's rated wattage per meter before sizing the installation.
Can the ELG-150-24DA replace a non-dimmable 24V driver in an existing LED strip installation if DALI control is added later?
Yes. The ELG-150-24DA is electrically compatible with 24V LED loads and operates as a standard 24V driver when no DALI signal is present (typically defaults to full output). Adding a DALI controller and bus wiring later enables dimming without replacing the driver again.
Does the ELG-150-24DA work across a wide mains input range, including 277V?
Yes. The input range is 100–305VAC, accommodating all common single-phase supply voltages from 120V to 277V without any selector switch. This makes it suitable for North American commercial buildings wired at 277V as well as international 230V installations.
