Output specifications

Parameter Specification
Full model XLN-40-H-B
Model code XLN-40 identifies the series; H identifies NFC-adjustable constant-current operation within a constant-power envelope. B identifies 3-in-1 dimming.
Output mode Multiple-stage constant power with selectable constant current.
Rated power 40 W, subject to input and temperature limits.
Default output current 1050 mA
NFC current adjustment 600–1400 mA; disconnect input power before NFC programming.
Constant-current operating region 9–54 V overall. The maximum permissible LED voltage depends on the selected current; 54 V is not available at every current setting.
Recommended current / voltage settings 600 mA: 9–54 V; 700 mA: 9–54 V; 800 mA: 9–50 V; 900 mA: 9–45 V; 1050 mA: 9–38 V (default); 1200 mA: 9–33 V; 1300 mA: 9–31 V; 1400 mA: 9–29 V. These are the catalog’s rounded recommended windows; observe the rated 40 W power envelope and I–V plot together. The plot labels 1400 mA at 28.6 V while the rounded table lists 29 V.
Open-circuit voltage 60 V; the output hiccups under no-load conditions.
Current ripple <4% at full load.
Current tolerance ±5% in the specification table. The NFC procedure separately states a set-current versus actual-current numerical error within 2%; it does not replace the overall tolerance.

Control and current setting

Parameter Specification
Fitted control function Built-in 3-in-1 dimming with dim-to-off.
NFC app and device Use an NFC-capable phone and the MEAN WELL app. The catalog specifies Android 4.1 or iOS 12 updates. Locate the phone antenna and driver NFC sensing mark.
NFC programming sequence Turn off the driver input supply. Enable phone NFC; open MEAN WELL → Installation Manual/APP → PowerNFC, approach the sensing position and read the model and settings. Enter the required output current, tap Write, bring the phone antenna close to the sensing mark, and confirm the app displays Success. The interface also provides Read, Default and password controls.
3-in-1 control inputs Apply 0–10 VDC, a 10 V PWM signal at 300 Hz–3 kHz, or 0–100 kΩ resistance between DIM+ and DIM−. Typical dimming-source current: 100 μA.
Dimming floor and off Minimum dimming is about 8%; output current is undefined between 0% and 8%. Output can fall to 0% at approximately 0 VDC, 0 kΩ, or 0% duty of the 10 V PWM control signal.
Synchronized resistance control The chart scales full-level resistance as 100 kΩ / N, where N is the number of drivers under synchronized dimming.
Control wiring restriction Do not connect DIM− to the negative LED output (−V). Direct connection to compatible LEDs is suggested; do not cascade an additional LED driver.
Dimming-off standby <0.5 W, measured at 230 VAC with dimming off.
NFC commissioning Use an NFC-enabled phone or tablet and the MEAN WELL app (Power NFC). Read and write parameters only with AC power off; otherwise internal magnetic interference can prevent normal current setting.
NFC reading and verification Keep the phone antenna less than 5 cm from the NFC tag. Read the current, edit the setting, then hold the antenna near the tag and select Setting. After Success, read the driver again to confirm that the intended current was saved.
NFC password The factory default has no password. A user password may contain up to 8 case-sensitive English letters or digits, with no special characters, and must be entered for subsequent writes. The password cannot be reset externally; retain it safely. Default restores the output current to its factory value.

Environment and derating

Parameter Specification
Working case temperature Tcase −25 to +90°C; maximum case temperature 90°C. This is a case limit, not the ambient operating limit.
Ambient temperature / load Horizontal mounting: the 100% load boundary runs from −25°C to +40°C at 110 VAC and to +50°C at 230 VAC for this output type. The plotted boundaries end vertically; they do not authorize operation beyond those limits.
Case-temperature / load The horizontal-mounting plot shows 100% load up to Tcase 90°C. Apply case, ambient, input and output limits together.
Low-input derating Static characteristic at 60 Hz: approximately 80% load at 100 VAC, rising to 100% at 110 VAC; 100% from 110 to 305 VAC within thermal limits.

Working and storage humidity Working: 20–90% RH, non-condensing. Storage: −40 to +80°C, 10–95% RH.
Temperature coefficient ±0.03%/°C over 0–50°C.
Vibration 10–500 Hz, 2G; 10 minutes per cycle, 60 minutes each along X, Y and Z axes.
Life expectancy >50,000 hours typical when the marked Tc point is about 75°C or less; a temperature-dependent expectation, not a guaranteed service-life duration.
Performance curves THD, PF and efficiency plots use the H model at Tcase 75°C, with 1050 mA and 1400 mA settings. Do not apply these curves as fixed-voltage-model guarantees.
