Frequently Asked Questions

Can I use the XLG-320-48-ABV to power 48V LED strip lighting in an outdoor sign cabinet?

Yes. The XLG-320-48-ABV is rated IP67, meaning it is fully protected against dust ingress and temporary water immersion, making it suitable for outdoor and enclosed sign cabinet installations. It supplies 48V at up to 6.5A with a 312W capacity, which is appropriate for driving 48V LED strip runs in signage applications.

Can this power supply drive a long run of 48V LED strip for architectural lighting?

Yes. At 312W and 48V, this driver can support up to 312W of 48V LED strip load — for example, roughly 31 meters of 10W/m strip or 20.8 meters of 15W/m strip. Always check your strip's rated power per meter and derate to 80% of the driver's max load for continuous use. The flicker-free constant voltage output also suits high-visibility architectural installations.

Does the XLG-320-48-ABV support dimming for tunable or dimmable LED strip systems?

Yes. This unit includes a 3-in-1 dimming function supporting 1-10V, PWM, and resistance dimming methods. The output is specified as flicker-free CV dimming, which is suitable for photography studios, retail displays, or any application sensitive to flicker.

Is the XLG-320-48-ABV suitable for wet or outdoor environments?

Yes. The IP67 rating means this driver is dustproof and can withstand temporary immersion in up to 1 meter of water for 30 minutes. Its operating temperature range of -20°C to +85°C also covers most outdoor climates. It is appropriate for exterior architectural lighting, outdoor sign boxes, and covered wet-location LED installations.

Can I adjust the output voltage on the XLG-320-48-ABV to fine-tune strip brightness?

Yes. The output voltage is adjustable, allowing you to trim the 48V output within a range to compensate for cable voltage drop in longer runs or to optimize LED strip brightness. This is particularly useful in constant voltage LED strip systems where precise voltage delivery affects uniform brightness along the strip.

How does the XLG-320-48-ABV compare to other 320W XLG models?

The XLG-320 series includes constant current (CC) models at high voltages (H, L, M variants) and constant voltage (CV) models like this one and the XLG-320-V-A. The XLG-320-48-ABV provides 312W at 48V (CV) with dimming, while the XLG-320-V-A offers 312W at 24V (CC) without dimming, and the H/L/M variants use constant current at much higher voltages for series LED string applications.
