FAQ

Can the XLG-50-AB be used to drive dimmable LED strip in an outdoor architectural lighting scheme?

Yes. The XLG-50-AB is IP67-rated for outdoor and wet-location use and includes dimming capability, making it suitable for exterior architectural cove lighting, garden path lighting, or outdoor accent strip installations where brightness control is required.

What LED strip length can the XLG-50-AB drive reliably?

The XLG-50-AB is a constant power LED driver with a rated output of 50W. It operates in a constant current region of 22~54V with a current adjustment range of 0.53~2.1A. For a 24V strip rated at 10W/m, the driver can support approximately 5 meters at full load. Confirm your strip's voltage and power per meter rating to ensure it falls within the driver's constant current region and power limits.

Can I use the XLG-50-AB for a dimmable LED display or illuminated sign that needs to run outdoors?

Yes. The combination of IP67 waterproofing and built-in dimming makes the XLG-50-AB a practical choice for dimmable outdoor sign cabinets, illuminated menu boards, and exterior display lighting where the driver must tolerate rain and dust. Its -40°C to +90°C operating range also handles outdoor thermal extremes.

Is the XLG-50-AB suitable for humid or splash-zone environments such as pool surrounds or outdoor bars?

Yes. The IP67 rating certifies protection against complete dust ingress and temporary water immersion to 1 meter for 30 minutes. This makes the XLG-50-AB appropriate for pool surround accent lighting, outdoor bar lighting, or similar wet-area LED strip applications, subject to applicable local electrical codes.

Can the dimming function on the XLG-50-AB be controlled by a standard 0-10V lighting controller?

Yes. The XLG-50-AB features a 3-in-1 dimming function compatible with 0~10VDC, 10V PWM signals, or resistance. You can control the dimming level by applying a 0~10VDC signal between the DIM+ and DIM- terminals. Note that DIM- should not be connected to Vo-.
