Frequently Asked Questions

Can I use the XLG-320-H-A to drive LED downlights in a commercial building?

Yes, the XLG-320-H-A is well-suited for powering LED downlight arrays in commercial settings. It delivers 312W at a constant 5600mA over a 30–56V output range, making it compatible with high-power downlight modules that operate in that voltage window. Its IP67 rating also allows installation in ceiling cavities or damp locations.

Is the XLG-320-H-A suitable for outdoor LED signage?

Yes, the IP67 waterproof rating means this driver can be mounted in outdoor enclosures or direct-exposure signage cabinets. It handles an input range of 142–431VAC and operates down to -40°C, so it performs reliably across harsh outdoor temperature extremes.

Can the XLG-320-H-A power a large LED array in an architectural lighting fixture?

Yes, the driver's 312W capacity and 5600mA constant-current output are appropriate for high-wattage architectural LED arrays whose total forward voltage falls between 30V and 56V. Because it operates in constant-current mode, LED count depends on each LED's forward voltage — you should verify the string voltage stays within the 30–56V CC range.

What LED forward voltage range is compatible with the XLG-320-H-A?

The XLG-320-H-A regulates constant current over a 30–56V output range. LEDs connected in series must have a combined forward voltage that falls within that range at the rated 5600mA. The exact number of LEDs depends on the forward voltage of each individual LED.

Can the XLG-320-H-A be used in cold-storage or refrigerated environments?

Yes, the operating temperature range of -40°C to +85°C covers typical cold-storage and refrigeration environments. The IP67-rated metal enclosure also protects against condensation and moisture ingress common in such installations.

How does the XLG-320-H-A differ from the XLG-320-H-AB in the same series?

Both models share the same 312W output, 5600mA current, 30–56V CC range, IP67 rating, and 246×77×39.5mm dimensions. The key difference is that the XLG-320-H-AB adds analog dimming capability, while the XLG-320-H-A supports output adjustment only and has no built-in dimming interface.

Does the XLG-320-H-A work with universal mains voltage worldwide?

The XLG-320-H-A accepts 142–431VAC input, which covers most global mains voltages including 200–240VAC systems common internationally. It carries CB, CE, UL, CCC, EAC, ENEC, and c_rcm certifications supporting broad international deployment.
