Catalog pages 40–46; specification revision 2026-02-04. Use the exact model and suffix when selecting wiring and operating conditions.

Output and operating envelope

Rated output	310.8 W; default current 2800 mA.
Constant-current voltage region	74–148 V, subject to the I–V operating envelope.
Full-power current range	2100–2800 mA. Full power requires a compatible LED forward voltage inside the published boundary.
Current adjustment	1050–2800 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: 1050 / 148; 2100 / 148; 2800 / 111; 2800 / 74; 2100 / 74. These delimit the operating area; voltage and current maxima cannot be combined as an unrestricted rectangle.
Open-circuit voltage	180 V maximum.
Current ripple / tolerance	5% ripple at full load; current tolerance ±5%, including setup tolerance, line regulation and load regulation.
Efficiency	93.5% typical in the specification table.

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: DALI-2 and built-in current adjustment; standard control configuration.
Standby power	<0.5 W with dimming OFF, for this standard DA2 version.

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	3.2 A at 120 VAC; 1.6 A at 230 VAC; 1.3 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 <15% at load ≥75% with 277 VAC.
Cold-start inrush	45 A typical at 230 VAC; 1200 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. 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 120 VAC; 100% from 120 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.

Cooling and reliability

Case-temperature rating	Working Tcase −40 to +85°C; maximum case temperature +85°C. This is a case rating, not an unrestricted ambient rating.
Ambient/load derating	For horizontal mounting: 120 VAC, this DA2 version: 100% through +40°C, where the low-line curve ends. 230 VAC: 100% through +45°C, then 95% at +50°C, where that curve ends. Meet the ambient-load curve and case-temperature limit together.
Case/load curve	For horizontal mounting, 100% load is plotted through Tcase +85°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.
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 85°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: 1397.7 K hours, Telcordia SR-332; 145.1 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.
