Frequently Asked Questions

Can the XLG-320-L-AB power dimmable LED modules in large indoor commercial fixtures?

Yes, the XLG-320-L-AB delivers 315W at 1400mA with a 150–300V CC output range and includes an analog dimming interface. This makes it suitable for large commercial fixtures using high-voltage LED strings that require adjustable light output without a separate external dimmer driver.

Is the XLG-320-L-AB suitable for outdoor LED street or area lighting that needs dimming?

Yes, the IP67 rating enables outdoor mounting, and the -40°C to +85°C operating range covers demanding climates. The built-in dimming input allows integration with outdoor lighting controllers for adaptive dimming in street or area lighting systems running LED strings in the 150–300V range.

Can the XLG-320-L-AB be used in high-bay LED luminaires with long LED strings?

Yes, high-bay fixtures often use series LED strings with accumulated forward voltages in the 150–300V range — exactly the CC operating window of this driver. At 315W and 1400mA, it can power substantial LED arrays in industrial or warehouse high-bay applications.

What forward voltage range must the LED load present to the XLG-320-L-AB?

LED strings must present a combined forward voltage between 150V and 300V at the 1400mA operating current. The actual number of LEDs in the string depends on each LED's individual forward voltage, and total dissipated power must remain within 315W.

Can the XLG-320-L-AB be installed in wet or outdoor locations?

Yes, the IP67 waterproof rating confirms dust-tight and temporary immersion protection, suitable for outdoor luminaires, wet-location fixtures, and enclosures subject to rain or washdown. Temperature operation spans -40°C to +85°C for year-round outdoor service.

What is the practical difference between the XLG-320-L-AB and the XLG-320-L-A?

Both drivers share 315W output, 1400mA current, 150–300V CC range, IP67 rating, and the same physical dimensions and certifications. The XLG-320-L-AB includes an analog dimming input that allows brightness control; the XLG-320-L-A provides output adjustment only and has no dimming interface.

Does the XLG-320-L-AB support wide input voltage for global installations?

Yes, the driver accepts 142–431VAC input, accommodating both 200–240VAC and higher-voltage mains supplies. CB, CE, CCC, UL, EAC, ENEC, and c_rcm certifications support international deployment across North America, Europe, Australia, and China.
