## Long description

The mean well XLN-40-12 is a constant-voltage LED power supply delivering 12V DC at up to 3.4A (40W).

How to use
Install the mean well XLN-40-12 on a stable surface or within an enclosure that allows adequate heat dissipation. Connect the AC input to a compatible mains supply following local electrical codes and ensure proper grounding. Connect the 12V DC output to the LED load, observing correct polarity. Verify total LED load does not exceed the rated 40W and allow the unit to cool during continuous operation. If used outdoors, position connections and any exposed wiring to maintain the IP67 integrity of the installation.
Usage recommendations
Confirm total LED wattage and cable lengths to avoid voltage drop; use appropriately sized conductors and keep the environment within the specified temperature range. For long-term reliability, avoid mounting directly on surfaces that inhibit heat dissipation and protect terminal areas from prolonged submersion despite the IP67 rating.
