Frequently Asked Questions

Can the XLG-320-M-A power LED downlights that require a mid-range output voltage?

Yes, the XLG-320-M-A provides constant current at 2800mA over a 74–148V output range, suitable for LED downlight modules or arrays with combined forward voltages in that window. Its 310.8W capacity supports high-power commercial downlight installations.

Is the XLG-320-M-A suitable for driving LED modules in outdoor area or sports lighting?

Yes, the IP67 waterproof rating and -40°C to +85°C temperature range support outdoor sports and area lighting fixtures. The 74–148V CC range accommodates mid-string-length LED arrays common in high-power outdoor luminaires at 2800mA.

Can the XLG-320-M-A be used in industrial high-bay LED fixtures?

Yes, 310.8W at 2800mA with a 74–148V operating range suits the LED string voltages found in many industrial high-bay designs. The metal case and IP67 rating also help in dusty industrial environments where ingress protection is required.

How many LEDs can the XLG-320-M-A drive in a constant-current string?

The number of LEDs is determined by each LED's forward voltage — there is no fixed count. The total forward voltage of all series-connected LEDs must fall between 74V and 148V at 2800mA, and total power must stay within 310.8W.

Can the XLG-320-M-A be installed in an outdoor pole or wall-mount luminaire?

Yes, the IP67 rating provides dust-tight and temporary-immersion protection, making the driver appropriate for outdoor pole-mount and wall-mount luminaire housings. Operating temperature extends to -40°C for cold-region outdoor installations.

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

Both models share 310.8W output, 2800mA current, 74–148V CC range, IP67 rating, and the same physical dimensions, weight, and certifications. The XLG-320-M-AB adds an analog dimming interface, while the XLG-320-M-A provides only output adjustment with no dimming input.

Does the XLG-320-M-A accept high-line input voltages common in industrial facilities?

Yes, the driver accepts 142–431VAC input, covering industrial supply voltages such as 277VAC (common in US commercial lighting) and 380–415VAC single-phase legs. CB, CE, CCC, UL, EAC, ENEC, and c_rcm certifications support global industrial deployment.
