FAQ

Can the XLG-50-L-DA2 drive a long series string of LED modules in linear signage?

Yes. The driver's CC voltage range of 60–142V allows a longer series string than lower-voltage variants, making it well suited for linear LED signage arrays where multiple modules are daisy-chained. The exact number of modules depends on each module's forward voltage.

Is the XLG-50-L-DA2 appropriate for LED downlights that require a mid-range series voltage?

Yes. At 50W with a 60–142V constant current region and 700mA output, this driver works with LED downlight strings whose combined forward voltages fall within that range. The adjustable current (300–700mA) allows you to match the driver's output to the fixture's rated current.

Can I use the XLG-50-L-DA2 in an outdoor LED display or signage cabinet?

Yes. The IP67 waterproof rating and -40°C to +85°C operating temperature range make this driver suitable for outdoor enclosures, including roadside signage cabinets exposed to weather and temperature swings.

How many LEDs can the XLG-50-L-DA2 support in a series circuit?

The driver's constant current region spans 60–142V, so the LED count depends on the forward voltage of each LED in the string. Select LEDs whose combined forward voltages fall within 60–142V at your desired operating current of up to 700mA.

What is the minimum dimming level of the XLG-50-L-DA2 when used with a DALI2 system?

The minimum dimming level is 8%. This is the lowest output the driver will sustain under DALI2 dimming commands before shutting off, which is suitable for most architectural dimming scenarios.

How does the XLG-50-L-DA2 compare to the XLG-50-H-DA2?

Both are 50W DALI2 drivers with IP67 ratings and the same compact 105 × 63 × 30 mm housing. The XLG-50-L-DA2 targets higher-voltage, lower-current strings with a CC region of 60–142V and adjustable current of 300–700mA, while the XLG-50-H-DA2 targets lower-voltage, higher-current strings with a CC region of 27–56V and adjustable current of 500–1400mA.
