Frequently Asked Questions

Can the XLG-320-L-A drive high-voltage LED strings used in commercial linear lighting?

Yes, the XLG-320-L-A outputs constant current at 1400mA over a 150–300V range, making it compatible with long series-connected LED strings typical of commercial linear or architectural luminaires. Its 315W capacity supports high-power linear runs where LED string voltages accumulate to the 150–300V window.

Is the XLG-320-L-A suitable for powering LED modules in large outdoor signage at high voltages?

Yes, the IP67 waterproof rating and -40°C to +85°C operating range support outdoor signage enclosures. The 150–300V CC output range targets LED strings with many series-connected LEDs, common in large-format illuminated signs where high string voltages reduce total current.

Can I use the XLG-320-L-A in a streetlight or roadway LED fixture?

Yes, the driver's 315W output, wide CC voltage range of 150–300V, and IP67 rating align well with outdoor streetlight and roadway fixture requirements. The operating temperature extends to -40°C, supporting cold-climate roadway installations.

How many LEDs can the XLG-320-L-A drive?

The number of LEDs depends on each LED's forward voltage — there is no fixed count. The combined forward voltage of all series-connected LEDs must fall within the 150–300V constant-current operating range at 1400mA. Verify the string voltage sum stays within those bounds at the operating current.

Is the XLG-320-L-A suitable for permanent outdoor installation without an additional enclosure?

The XLG-320-L-A carries an IP67 rating, providing dust-tight and temporary-immersion protection. It is appropriate for outdoor luminaires and can be mounted in pole or wall fixtures that expose the driver to weather, operating across -40°C to +85°C.

What distinguishes the XLG-320-L-A from the XLG-320-L-AB in the same series?

The XLG-320-L-A and XLG-320-L-AB share identical output ratings — 315W, 1400mA, 150–300V CC range — as well as the same dimensions, weight, IP67 rating, and certifications. The XLG-320-L-AB adds a built-in analog dimming interface; the XLG-320-L-A supports output adjustment only with no dimming input.

Does the XLG-320-L-A accept 400VAC three-phase derived input voltages?

The XLG-320-L-A accepts 142–431VAC single-phase input, which encompasses rectified phase-to-neutral voltages derived from 400VAC three-phase supplies. It is certified to CB, CE, CCC, UL, EAC, ENEC, and c_rcm standards covering both single-phase and relevant international grid voltages.
