Frequently Asked Questions
Can the XLG-20-M power LED downlights in a commercial ceiling grid?
Yes. The XLG-20-M provides 21W at 500mA constant current with a 25–42V output range, suitable for mid-power LED downlight modules within that voltage band. Its IP67 rating also permits installation above damp-area ceilings where condensation may be present.
Is the XLG-20-M appropriate for driving LED modules in illuminated signage?
Yes. At 500mA and 21W with a 25–42V constant current range, it can drive LED signage modules whose forward voltage falls within that range. IP67 protection supports outdoor sign cabinets subject to rain or washdown.
Can I use the XLG-20-M for a small LED array in track lighting?
Yes, provided each LED array's combined forward voltage falls between 25V and 42V at a 500mA drive current. The driver's metal case and high efficiency (up to 90%) limit heat dissipation in tight track fixtures.
What is the operating temperature range of the XLG-20-M, and can it be installed outdoors?
The XLG-20-M operates from –40°C to +80°C and carries an IP67 waterproof rating. It can be installed in outdoor enclosures exposed to rain, dust, and cold-climate temperatures.
Does the XLG-20-M support dimming?
No. The XLG-20-M (without a '-B' suffix) does not include built-in dimming circuitry. For dimming capability, the XLG-20-M-B variant adds 3-in-1 PWM, resistance, and 1–10V analog dimming support.
How many LEDs can be driven in series by the XLG-20-M?
The driver outputs 500mA over a constant current range of 25–42V. The number of series LEDs depends on each individual LED's forward voltage — no fixed count applies. Confirm the total string forward voltage is within 25–42V at 500mA.
