Rated output
42 V DC; 11.4 A; 478.8 W
Constant-current region
21–42 V. Keep the LED operating voltage within this region for direct constant-current operation; stay within the rated and derated current/power envelope.
Output mode
Constant voltage + constant current. Actual CV/CC transition depends on the LED load. The operation diagram also illustrates CV supply of an external DC/DC stage; the dimming restrictions below apply to dimmable versions.

250 mVp-p
Voltage tolerance
±1%, including set-up, line and load regulation
Line / load regulation
±0.5% / ±0.5%

Efficiency
95% typical at 230 VAC; 95.5% typical at 277 VAC
Setup / rise time
500 ms / 80 ms at both 115 and 230 VAC. Catalog timing is measured at the first cold start; repeated ON/OFF operation may increase setup time.

Circuit-breaker loading
Catalog reference: 2 / 3 units on B-type / C-type 16 A breakers at 230 VAC. Confirm breaker characteristics and the actual installation; these are configuration-dependent catalog values.

Input/load derating
At 60 Hz: 90 VAC: 80% load; 110–305 VAC: 100% load. Between plotted endpoints, follow the catalog curve; this does not authorize overload.
Over-current protection
95–108% of rated output; constant-current limiting, with automatic recovery after the fault is removed.
Short-circuit protection
Constant-current limiting; automatic recovery after the fault is removed.
Over-voltage protection
46–55 V; Output shuts down; re-power to recover.
Over-temperature protection
Output shuts down; re-power to recover.
Control and option-specific functions
Smart timer
By-request smart timer dimming. Adaptive proportional timing follows the supplied profile; arrange the customer schedule with MEAN WELL. The D01/D02/D03 plots are examples, not a promise that this DX order includes a particular preset.
Catalog timer examples
Elapsed hours from switch-on: D01 = 0–6 h 100%, 6–7 h 70%, 7–11 h 50%, 11–14 h 70%; D02 = 0–1 h 50%, 1–3 h 80%, 3–8 h 100%, 8–11 h 60%, 11–14 h 80%; D03 = 0–1.5 h 70%, 1.5–11 h 100%, 11–14 h 70%. Use the elapsed-time tables; the example clock labels contain inconsistencies.
Thermal and environmental limits
Cooling / ambient derating
Fanless free-air convection. Horizontal mounting: at 110 VAC, 100% load through +50°C; on the curve labeled above 230 VAC, 100% through +60°C. Both reach 60% at +65°C. The plotted ambient range starts at −40°C. The catalog gives a typical +60°C maximum ambient at rated constant current and 230 VAC.
Case temperature
Working case temperature Tc = −40 to +90°C; +90°C maximum. Use the Tc point in the mechanical drawing. Ambient temperature and Tc are separate limits.
Case-temperature measuring point

Measurement and installation conditions

Performance-curve conditions
Power-factor, THD and efficiency plots use Tc = 75°C; the THD/efficiency plots are for the 42 V model. Example-model curves do not replace the efficiency and operating limits listed for this exact SKU.
LED compatibility
Select an LED load compatible with the voltage/current window, startup behavior, thermal limits and the selected control option. Consult the catalog and manufacturer for configurations outside the illustrated operating regions.
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. 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.
Protective-earth installation
Connect the fitted FG/PE conductor or protective-earth terminal to PE according to this Class I model’s wiring diagram.
Timer ordering
This DX version uses customer-defined smart-timer dimming by request. Confirm the ordered profile and operating procedure with MEAN WELL; DX does not mean DALI or DALI-2.
