FAQ

Can the XLG-240-M-AB be dimmed using a standard 0-10V lighting controller?

Yes. The AB suffix indicates a built-in dimming interface compatible with 0-10V DC, 10V PWM signal, and resistance control signals. This allows the driver to integrate with occupancy sensors, daylight harvesting systems, or building management systems.

Is the XLG-240-M-AB appropriate for dimmable LED high-bay or pendant fixtures in commercial spaces?

Yes. With 239.4W of constant-current output and a 90–171V CC voltage range, the XLG-240-M-AB is well matched to medium-voltage LED module strings used in commercial pendants, high-bays, and linear architectural fixtures where dimming control is required.

Can I install the XLG-240-M-AB in an outdoor enclosure exposed to rain?

Yes. The IP67 waterproof rating confirms protection against dust and water immersion, making the driver suitable for outdoor or wet-location luminaire housings. Its -40°C to +90°C range also handles extreme ambient temperatures.

Will the XLG-240-M-AB work with LED modules in the 100–150V forward voltage range?

Yes. The CC voltage range of 90–171V encompasses LED module strings with forward voltages between 90V and 171V, which includes many medium-voltage commercial module arrays. The driver regulates output current at 1.4A within that window.

How does the XLG-240-M-AB differ from the XLG-240-M-A?

Both share the same 239.4W output, 90–171V CC voltage range, 1.4A output current, and IP67 rating in the same enclosure. The XLG-240-M-AB adds a 3-in-1 dimming control input (0-10V, PWM, resistance) alongside the built-in potentiometer; the XLG-240-M-A offers only manual current adjustment via potentiometer. Choose the AB variant when external dimming is needed.

Does the XLG-240-M-AB support universal input voltage for global or multi-site deployments?

Yes. The 100–305VAC input range covers 120V, 230V, 240V, and 277V mains supplies without any manual reconfiguration, making it practical for projects spanning multiple regions or voltage standards.
