Information about the MEAN WELL XLN-40-H

With the XLN-40-H, MEAN WELL offers a compact, fully encapsulated 40W Constant Power LED driver built inside an IP67-rated Class II plastic case. This driver is specifically designed to provide high flexibility for modern LED fixtures requiring precise current adjustment.

A primary feature of the XLN-40-H is its programmable output current via NFC technology. Using the official MEAN WELL mobile app, installers can wirelessly configure the output current between 600 mA and 1400 mA while the unit is powered off (factory default set to 1050 mA). The power supply automatically adjusts its output voltage between 9 and 54 VDC to maintain constant power performance.

The unit supports a universal input voltage range of 100 to 305 VAC as well as DC input (141–400 VDC), making it compliant for emergency lighting installations (EL function per EN61347-2-13 Appendix J at 176–280 VDC). Featuring high operational efficiency up to 88% and a fanless convection-cooled design, it operates reliably across case temperatures ranging from -25°C to +90°C.

Engineered to satisfy EU ErP lighting directives, the XLN-40-H provides flicker-free lighting and consumes less than 0.5 W in standby mode. Combined with built-in protections against short circuits, overvoltage, and thermal overload, the driver guarantees outstanding reliability. Backed by extensive international safety certifications (UL8750 Class P / Type HL, ENEC, EAC) and a 5-year warranty, the XLN-40-H is an optimal choice for downlights, panels, and commercial lighting setups.
