Output and operating envelope
Rated output
239.6 W; default current 4900 mA.
Constant-current voltage region
27–56 V, subject to the I–V operating envelope.
Full-power current range
4280–6660 mA. Full power requires a compatible LED forward voltage inside the published boundary.
Current adjustment
2400–6660 mA via the built-in potentiometer. The catalog describes full-power operation in its 70–100% constant-power mode; use the exact boundary below and do not exceed the LED load rating.
I–V boundary points
Catalog vertices in mA / V: 2400 / 56; 4280 / 56; 6660 / 36; 6660 / 27; 4400 / 27. These delimit the operating area; voltage and current maxima cannot be combined as an unrestricted rectangle.
Open-circuit voltage
65 V maximum.
Current ripple / tolerance
5% ripple at full load; current tolerance ±5%, including setup tolerance, line regulation and load regulation.
Efficiency
93% typical in the specification table. With the auxiliary output delivering its full 3 W, the catalog specifies a 1% efficiency drop.
Auxiliary output
12 V / 250 mA; tolerance ±10%; ripple 200 mVp-p. This DA2-A configuration is supplied by request. Its auxiliary output is separate from the main LED output.
Dimming and configuration
DALI-2 interface
IEC 62386-101, -102, -207 and -251; device type 6 (DT6). Apply the DALI signal between DA+ and DA−. The protocol provides 16 groups and 64 addresses; the first dimming step is fixed at 8% of output.
Control configuration
DA2-A: DALI-2, built-in current adjustment and auxiliary supply; by request. This I model is the India input-protection version, supplied by request.
Input and power quality
Input supply
100–305 VAC or 142–431 VDC; 47–63 Hz for AC. Observe low-line load derating. The emergency-installation approval has the narrower DC range stated under safety.
AC input current
2.7 A at 115 VAC; 1.3 A at 230 VAC; 1.1 A at 277 VAC; typical.
Power factor
Typical PF ≥0.97 at 115 VAC, ≥0.95 at 230 VAC and ≥0.92 at 277 VAC, at full load; active PFC.
Total harmonic distortion
THD <10% at load ≥50% with 115/230 VAC; THD <10% at load ≥75% with 277 VAC.
Cold-start inrush
85 A typical at 230 VAC; 500 µs width measured at 50% of peak, per NEMA 410.
Circuit-breaker reference
Maximum catalog count at 230 VAC on a 16 A circuit breaker: 2 B-type / 4 C-type. Confirm the actual breaker and installation conditions.
Leakage current
<0.75 mA at 277 VAC.
Setup time
500 ms at 230 VAC; 1200 ms at 115 VAC. Measured at first cold start; repeated ON/OFF operation can lengthen setup time. High internal temperature can further lengthen it. The 500 ms timing requires a controller supporting the IEC 62386-101/-102 DALI power-on function; otherwise setup can take longer.
Input/load derating
At 60 Hz: 80% load at 100 VAC, increasing to 100% at 110 VAC; 100% from 110 to 305 VAC.
Protection
Short circuit
Hiccup mode or constant-current limiting; automatic recovery after the fault condition is removed.
Overtemperature
Stage 1 derates to 75% loading; stage 2 derates to 50% loading. Automatic recovery after the fault condition is removed.
Input overvoltage protection
India I version only: 320–390 VAC protection range; the output shuts down when the input exceeds the protection voltage, then recovers automatically after the fault is removed. Survival of 440 VAC input stress for 48 hours is specified; 440 VAC is not a continuous operating-input rating.
Cooling and reliability
Case-temperature rating
Working Tcase −40 to +90°C; maximum case temperature +90°C. This is a case rating, not an unrestricted ambient rating.
Ambient/load derating
For horizontal mounting: 110 VAC, this DA2-A version: 100% through +35°C, then 50% at +50°C. 230 VAC: 100% through +50°C, then 50% at +60°C. Each curve ends at its stated final point. Meet the ambient-load curve and case-temperature limit together.
Case/load curve
For horizontal mounting, 100% load is plotted through Tcase +90°C and the curve ends there.
Low-temperature startup
The −40 to −30°C portion of the temperature curves is for 230 VAC input only. Below 120 VAC at −30°C, restarting may occur within the first 5 seconds after power-on.
Cooling and altitude
Fanless free-air convection. Derate nonstandard mounting as required. Above 2000 m, reduce allowed ambient temperature by 3.5°C per additional 1000 m.
Humidity and storage
Working: 20–95% RH, non-condensing. Storage: −40 to +80°C, 10–95% RH, non-condensing.
Temperature coefficient / vibration
±0.06%/°C over 0–60°C. Vibration: 10–500 Hz, 5 G; 12 minutes per cycle, 72 minutes along each X, Y and Z axis.
Performance-plot conditions
PF curves use Tcase 75°C. THD and efficiency curves use the L-DA2 example at Tcase 75°C; they do not replace this output branch’s tabulated efficiency.
Lifetime / MTBF
Typical life >50,000 hours when the marked tc/TMP point is about 75°C or less. MTBF minimum estimates: 1988.7 K hours, Telcordia SR-332; 170.5 K hours, MIL-HDBK-217F at 25°C.

Application and installation 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.
ErP switching requirement
Use this driver behind a switch; it must not remain permanently connected to the mains.
Application selection
Catalog applications include street, flood, stage, fishing, horticulture and bay lighting. Select a compatible LED module, DALI controller and enclosure; observe this exact output branch’s safety and environmental restrictions.
