Information about the MEAN WELL XLN-40-H-B

With the XLN-40-H-B, MEAN WELL introduces a highly versatile, fully encapsulated 40W Constant Power LED driver featuring integrated 3-in-1 dimming control. Built inside an IP67-rated Class II plastic case, this driver is designed for modern, analog-controlled lighting systems.

A standout capability of the XLN-40-H-B is its programmable output current via NFC technology. Using the official MEAN WELL mobile app, system integrators can wirelessly adjust the output current from 600 mA to 1400 mA while the driver is powered off (factory set to 1050 mA). The power supply dynamically manages its output voltage between 9 and 54 VDC to maintain constant power performance.

The unit supports a universal input range of 100 to 305 VAC as well as DC input (141–400 VDC), making it fully compliant for emergency lighting installations (EL function per EN61347-2-13 Appendix J at 176–280 VDC). Featuring universal 3-in-1 dimming, it allows smooth brightness adjustments via 0–10V DC, a 10V PWM signal, or resistance (potentiometer).

Engineered for compliance with ErP lighting guidelines, the driver provides flicker-free performance and consumes less than 0.5 W in standby mode. Combined with multi-stage overtemperature derating and complete circuit protections, the unit guarantees high operational safety. Backed by global approvals (UL8750 Class P / Type HL, ENEC, EAC) and a 5-year warranty, the XLN-40-H-B is a premium choice for recessed lights, commercial panels, and architectural lighting.
