FAQ

Can I use the XLC-25-12-S to power 12V LED strips in a pendant luminaire or hanging fixture?

Yes, the XLC-25-12-S is a good choice for pendant or hanging luminaires where the output cable may experience mechanical stress from the fixture's weight or movement. The strain-relief feature secures the cable exit point, reducing the risk of wire fatigue at the connector. The driver supports up to 25.2W at 12V, suitable for short to medium runs of 12V LED strip.

Is the XLC-25-12-S suitable for use inside a 12V LED downlight housing?

Yes, the XLC-25-12-S is designed for built-in use and its compact 147.0 × 32.0 × 40.0 mm body fits within many downlight or recessed luminaire back boxes. The wide operating temperature range of -25°C to +85°C accommodates the heat that can build up inside enclosed downlight housings. The flicker-free output is beneficial for occupied spaces where flicker sensitivity matters.

Can I use the XLC-25-12-S in a 12V LED under-cabinet lighting strip installation?

Yes, the XLC-25-12-S is well suited for under-cabinet 12V LED strip lighting where the driver may be mounted inside a cabinet or behind a panel with the cable routed through a cutout. The strain-relief prevents mechanical stress on the cable at the driver exit, and the 25.2W capacity can power up to approximately 1.75 m of 14.4 W/m strip (25.2 ÷ 14.4 ≈ 1.75 m) — check your strip's rated power per meter for exact sizing.

How much 12V LED strip can the XLC-25-12-S drive?

The XLC-25-12-S outputs up to 25.2W at 12V and 2.1A. Divide 25.2W by your strip's rated watts per meter to get maximum length — a 10 W/m strip gives up to 2.52 m, while a 14.4 W/m strip gives approximately 1.75 m. Always check your specific strip's rated power per meter, and for continuous use plan for no more than 80% of the driver's rated output.

What certifications does the XLC-25-12-S hold, and is it approved for use in the EU?

The XLC-25-12-S carries ENEC, EAC, and UL8750 Class P certifications. The ENEC mark confirms compliance with European safety requirements for luminaire power supplies, and the UL8750 Class P designation confirms suitability for use in the US and Canada. It is suitable for use throughout the EU, EEA, and North America.

Is the XLC-25-12-S rated for outdoor or wet locations?

The XLC-25-12-S does not carry an IP ingress protection rating listed in its specifications, which means it is not rated for direct outdoor exposure or wet locations. It is intended for dry, built-in installations inside luminaires or enclosures. For outdoor-exposed or damp-location applications, a driver with an appropriate IP65 or higher rating should be selected.
