Frequently Asked Questions

Can the XLG-240-M-DA2 power LED downlights in a multi-zone commercial space with DALI controls?

Yes. The XLG-240-M-DA2 provides 239.4W at 1400mA constant current (90–171V CC range) with DALI2 dimming, making it suitable for mid-to-high power LED downlight arrays in commercial spaces managed by a DALI building automation system. Dimming is supported down to an 8% minimum level.

Is this driver appropriate for large LED signage modules that need DALI-based scheduling?

Yes. The IP67 rating and –40°C to +90°C operating range suit outdoor sign enclosures. At 239.4W and 1400mA with a 90–171V constant current region, it can drive medium-current LED sign modules with DALI2-controlled brightness scheduling.

Can the XLG-240-M-DA2 be used in architectural or hospitality LED array installations requiring smooth DALI dimming?

Yes. The DALI2 interface provides smooth 8%–100% dimming compatible with hospitality and architectural control systems. The 239.4W output at 1400mA with a 90–171V CC range accommodates multi-module LED arrays in hotels, theatres, and similar venues.

What is the current adjustment range of the XLG-240-M-DA2?

The output current is adjustable from 700mA to 2100mA, with 1400mA as the nominal rating. The DALI2 minimum dimming level is 8% of the configured output current.

Can the XLG-240-M-DA2 be installed in damp or cold outdoor environments?

Yes. The driver is rated IP67 waterproof and operates from –40°C to +90°C, supporting installation in outdoor enclosures, unheated plant rooms, and cold storage facilities. The 100–305VAC input covers global mains voltages.

How many LEDs can be connected in series to the XLG-240-M-DA2?

The constant current output region spans 90–171V at 1400mA. The number of LEDs in a series string depends on each individual LED's forward voltage — no fixed count can be given. Ensure the total string forward voltage is within 90–171V at the chosen drive current.

How does the XLG-240-M-DA2 compare to the XLG-240-H-DA2 and XLG-240-L-DA2?

All three are 239–240W, DALI2, IP67 drivers in the XLG-240 series. The XLG-240-H-DA2 outputs 4900mA over a 27–56V CC region; the XLG-240-M-DA2 outputs 1400mA over a 90–171V CC region; the XLG-240-L-DA2 outputs 700mA over a 178–342V CC region. Select based on your LED string's forward voltage and required drive current.
