Rated power / current
74.9 W / 700 mA
Constant-current region
53–107 V; the LED operating point must remain in the shaded I–V envelope.
Full-power current range
700–1050 mA; constant-power operation within the specified envelope, subject to temperature and input-voltage derating.
Maximum open-circuit voltage
115 V
Output-current adjustment
350–1050 mA via built-in potentiometer; adjustment and full-power ranges are different.
Current ripple / tolerance
5.0% at full load / ±5%; tolerance includes setup, line regulation and load regulation.
I–V selection boundaries
350 mA/107 V; 700 mA/107 V; 1050 mA/71 V; 1050 mA/53 V; 700 mA/53 V. These plotted boundary coordinates are rounded reference points; select within the shaded region and rated power, not an unrestricted voltage/current rectangle.
Nominal constant-power operation
The series feature describes full-power operation over 70–100% of its constant-power region; use the exact model current and I–V limits above.
Auxiliary output
This exact 50–100 W DA2 model has no specified 12 V/250 mA auxiliary output. That option belongs to the DA2-A versions in the 150–320 W families.
DALI-2 control
Control interface
DALI-2 control between DA+ (purple) and DA− (pink), with 16 groups and 64 addresses. The first dimming step is fixed at 8% of output.
Protocol
IEC 62386-101, -102, -207 and -251; device type 6 (DT6). Output and dimming circuitry use isolation as described in the datasheet.
Setup time
500 ms at 230 VAC; 1200 ms at 115 VAC, measured at the first cold start. Repeated ON/OFF switching can increase the setup time.
DALI startup condition
IEC 62386-101/102 timing and interruption testing requires a DALI controller supporting the DALI power-on function; otherwise setup may exceed 500 ms.
Standby power
The <0.5 W dimming-off figure is specified only for the standard version; it is not assigned to this India version.
Input and electrical performance
Input range / frequency
100–305 VAC / 142–431 VDC / 47–63 Hz.
Typical efficiency
90% at the model-specific specification conditions.
Power factor
≥0.97 at 115 VAC, ≥0.95 at 230 VAC and ≥0.92 at 277 VAC, at full load.
THD
<10% at ≥50% load for 115/230 VAC, and ≥75% load for 277 VAC.
AC input current
1 A / 0.45 A / 0.38 A at 115 / 230 / 277 VAC respectively.
Cold-start inrush
50 A, 360 μs pulse width measured at 50% of peak, at 230 VAC; per NEMA 410.
16 A circuit-breaker loading
8 units on type B / 14 units on type C at 230 VAC.
Leakage current
<0.75 mA at 277 VAC.
Input-voltage derating
At 60 Hz, the static graph permits 100% load across 100–305 VAC, subject to the separate thermal and operating-region limits.
Typical-curve conditions
PF is plotted in constant-current mode at Tcase 75°C. THD and efficiency graphs use XLG-75-L-DA2 at Tcase 75°C and 115/230/277 VAC; these are typical curves, not additional guaranteed ratings.
Switching-frequency references
PFC 50–120 kHz; PWM 65 kHz.
Protection
Short-circuit protection
Hiccup mode or constant-current limiting; automatically recovers after the fault is removed.
Overtemperature protection
Stage 1 reduces output to 75% loading; stage 2 reduces output to 50% loading. Operation recovers automatically after the fault condition is removed.
Input-overvoltage protection
320–390 VAC protection range for this India version: shuts down output when input exceeds the protection threshold and automatically recovers after the fault is removed. The 440 VAC / 48-hour withstand statement is a fault-stress capability, not the normal operating-input range.
Surge immunity
4 kV line-to-line / 6 kV line-to-earth; BS EN/EN 61000-4-5.
Temperature and reliability
Case temperature
Tcase −40 to +90°C; maximum case temperature +90°C. Case-temperature ratings are separate from ambient-temperature limits.
Ambient-temperature derating
Horizontal mounting with free-air convection: at 230 VAC, 100% load through Ta 60°C, reducing to 60% at Ta 70°C; at 100 VAC, 100% through Ta 50°C, reducing to 60% at Ta 60°C. The curves end at those limits; do not extrapolate them.
Cold operation
The −40 to −30°C portion is specified for 230 VAC input only. Below 120 VAC at −30°C, restarting may occur within 5 seconds after power-on.
Case-temperature load curve
The horizontal-mounting curve maintains 100% load to Tcase 90°C and ends there; it does not extend the ambient-temperature range.
Working humidity
20–95% RH non-condensing.
Storage
−40 to +80°C; 10–95% RH, non-condensing.
Temperature coefficient
±0.03%/°C over 0–60°C.
Vibration
10–500 Hz, 5 G; 12 minutes per cycle, 72 minutes on each X, Y and Z axis.
Altitude derating
Above 2000 m (6500 ft), reduce permitted ambient temperature by 3.5°C per additional 1000 m for this fanless model.
Life expectancy / warranty
Typical operating life >50,000 hours when the tc point (TMP per DLC) is about 75°C or below; 5-year warranty subject to MEAN WELL terms. The lifetime graph is a temperature-dependent estimate, not an extension of the warranty.
MTBF
2489.3 K hours minimum, Telcordia SR-332 (Bellcore); 245.7 K hours minimum, MIL-HDBK-217F at 25°C.

Model availability
Confirm this exact standard or India version and the required certification when ordering. Datasheet catalog stock notes are not live store inventory.
Installation manual requirements
Installation safety
Disconnect the mains supply and prevent accidental reconnection before installation or maintenance. Have faults examined by a qualified technician; do not open the power-supply case yourself.
Ventilation and mounting
Keep ventilation clear and do not stack objects on the unit. Keep 10–15 cm clearance when the adjacent device is a heat source. Follow this model’s mounting, ambient-temperature and output-derating requirements.
System wiring and protection
Use approved primary and secondary wiring rated for at least the applicable unit current. Connect the fitted PE/FG lead to protective earth according to the model wiring. Provide suitable system-level insulation and an enclosure around single-insulated wiring; verify EMC again in the completed system.
Environmental and load limits
Do not immerse the unit or install it near fire or above its specified ambient limit. Keep output current and power within the model’s rated operating envelope. If a fitted external flexible cable is damaged, replacement is limited to the manufacturer, its service agent or a similarly qualified person.
Connection seals and support
If waterproof connectors are fitted, secure their connections to prevent water entry. Verify the mounting structure and luminaire strength; use safety cables for bay-light applications.
Adjustable-unit weather protection
This IP67 model has a built-in output-current adjustment function. Install it indoors or in a location sheltered from rain outdoors, as required by the installation manual. IP67 does not permit immersion.
DALI-controller installation
Verify the compatibility and capacity of the DALI controller and network for the actual installed units. For standalone use with DALI conductors smaller than 18 AWG (0.75 mm²), use SELV controllers/networks; contact MEAN WELL for guidance before using FELV control. Follow this exact model’s DALI wiring.
Confirm the exact LED load, operating temperature, control interface and installation requirements against the linked datasheet and manual before commissioning.
