Output specifications

Parameter Specification
Full model XLN-25-H-DA2
Model code XLN-25 identifies the series; H identifies NFC-adjustable constant-current operation within a constant-power envelope. DA2 identifies DALI-2 and PUSH dimming.
Output mode Multiple-stage constant power with selectable constant current.
Rated power 25 W, subject to input and temperature limits.
Default output current 700 mA
NFC current adjustment 300–1050 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 300 mA: 9–54 V; 350 mA: 9–54 V; 400 mA: 9–54 V; 500 mA: 9–50 V; 600 mA: 9–42 V; 700 mA: 9–36 V (default); 900 mA: 9–28 V; 1050 mA: 9–24 V. These are the catalog’s rounded recommended windows; observe the rated 25 W power envelope and I–V plot together.
Open-circuit voltage 60 V; the output hiccups under no-load conditions.
Current ripple <4%.
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 DALI-2 DT6 digital dimming and primary-side PUSH dimming; minimum DALI dimming level 0.1%.
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.
DALI protocol DALI-2 DT6; IEC 62386-101, -102 and -207. Connect the DALI controller to the DA+ / DA− pair according to the catalog diagram.
PUSH control wiring Primary-side PUSH uses the DA+/PUSH lead through a momentary push button to AC/L, and DA−/N to AC/N. This is a mains-side connection; follow the manufacturer’s wiring diagram.
PUSH timing Factory dimming level: 100%. Short push 0.1–1 s toggles on/off; double click within 1.5 s sets 100%; long push 1.5–10 s changes brightness and reverses direction on each long push. Pulses shorter than 0.05 s do not change status.
PUSH system limits Up to 10 drivers on one common push button; maximum cable length from the button to the last driver is 20 m.
DALI startup condition The specified startup timing requires a DALI controller supporting the DALI power-on function; otherwise startup can exceed 0.5 s.
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 +85°C; maximum case temperature 85°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 85°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.
Cooling and altitude Free-air convection. Above 2000 m, derate the allowed ambient temperature by 3.5°C per additional 1000 m for this fanless model.
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 70°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 700 mA and 1050 mA settings. Do not apply these curves as fixed-voltage-model guarantees.
