Output and function

Rated output 1050 mA constant current; 320 W rated power.
Constant current region 152.4–304.8 V. Select the LED load within this range; the highest output voltage depends on the system configuration. Contact MEAN WELL for compatibility questions.
Open-circuit voltage 311 V maximum.
Current accuracy Current tolerance: ±5%. Current ripple: 5% maximum at rated current.
Function and ingress rating D2 type; IP67. Built-in smart timer dimming with a programmable function, available by request.
Current adjustment No internal user-adjustable current potentiometer is specified for this suffix.
LED connection This series operates in constant current mode to drive LEDs directly. The exact current option and function suffix determine the operating limits.
Smart timer profile Adaptive proportional current profiles may run for up to 14 consecutive hours. The actual profile must be agreed with MEAN WELL; examples do not establish the factory program for this SKU.
Residential example D01 Elapsed time after power-on: 100% for 0–6 h, 70% for 6–7 h, 50% for 7–11 h, then 70% for 11–14 h.
Street example D02 Elapsed time: 50% for 0–1 h, 80% for 1–3 h, 100% for 3–8 h, 60% for 8–11 h, then 80% for 11–14 h.
Tunnel example D03 Elapsed time: 70% for 0–1.5 h, 100% for 1.5–11 h, then 70% for 11–14 h. These intervals follow the software tables; some clock-time examples in the catalog are inconsistent. Confirm the commissioned schedule.
Programming interface The purple and pink control pair is PROG+ / PROG− for D2. It is not the B-type analog DIM input. D2 denotes the programmable option and does not mean the D02 example profile.
Catalog option By request; confirm specification and availability with MEAN WELL.

Input and performance

Input range 180–528 VAC or 254–747 VDC; 47–63 Hz AC. Apply the voltage-specific thermal limits.
AC current and power factor Typical AC current: 1.1 A at 347 VAC; 0.8 A at 480 VAC. Full-load typical PF: ≥0.98 / ≥0.97 / ≥0.95 / ≥0.93 at 230 / 277 / 347 / 480 VAC.
Efficiency and harmonic distortion Typical efficiency: 93.5%. THD <20% at loads ≥50% at 230, 277 and 347 VAC; 60% at 480 VAC.
Set-up time 500 ms at 230, 347 and 480 VAC. Measured at first cold start; repeated power cycling may increase set-up time.
Mains loading Typical cold-start inrush: 50 A; 920 µs pulse width measured at 50% Ipeak at 480 VAC, per NEMA 410. Maximum units on a 16 A type B / type C circuit breaker at 480 VAC: 2 / 4.
Leakage and measurement conditions Leakage current <0.75 mA at 480 VAC. Unless otherwise stated, specifications use 347 VAC, rated output current and 25°C ambient. Separate rise-time, hold-up-time and idle-power values are not stated.

Protection

Short circuit Constant current limiting; automatic recovery when the fault is removed.
Overvoltage 320–351 V; shuts down output voltage; re-power to recover.
Overtemperature Shuts down and latches off output voltage; re-power to recover.

Temperature and reliability

Case and ambient limits Operating case temperature: −40 to +90°C, with maximum Tcase +90°C. Horizontal installation: at 180 VAC, 100% load from −40 to +50°C, then 60% at +60°C; at 230 VAC, 100% through +55°C, then 60% at +65°C; above 277 VAC, 100% through +60°C, then 60% at +70°C. The case-temperature load curve shows 100% from −40 to +90°C. Meet both case and ambient limits; free-air convection cooling.
Input and altitude derating The 60 Hz static graph shows 100% load from 180 to 528 VAC; the notes still require assessment of low-input derating. Follow the separate voltage-dependent ambient-temperature curves. Above 2,000 m altitude, reduce allowable ambient temperature by 3.5°C per 1,000 m for this fanless design.
Environment Working humidity: 20–95% RH, non-condensing. Storage: −40 to +80°C, 10–95% RH. Temperature coefficient: ±0.03%/°C over 0–60°C. Vibration: 10–500 Hz, 5 G, 12 min/cycle, 72 min along each X, Y and Z axis.
Operating curves PFC switching frequency 45 kHz; PWM switching frequency 50 kHz. PF curves use Tc 80°C; THD and efficiency examples use the 700 mA model at Tc 80°C, distinguishing 230, 277, 347 and 480 VAC. These examples do not guarantee identical performance for every current option.
Life and reliability Typical lifetime >50,000 hours at Tc / TMP about 80°C or lower. The lifetime graph indicates approximately 100,000 h at Tc 20–70°C, 70,000 h at 75°C, 50,000 h at 80°C, 35,000 h at 85°C and 25,000 h at 90°C. MTBF: 1721.7K hours minimum, Telcordia SR-332 (Bellcore); 146.9K hours minimum, MIL-HDBK-217F at 25°C.
Warranty Five-year manufacturer warranty, subject to its warranty statement and the specified operating conditions.

System integration The driver is a component; final equipment manufacturers must re-qualify EMC for the complete installation. For the stated ErP luminaire requirement, use behind a mains switch without a permanent unswitched mains connection. The product is intended for North American and EU lighting equipment; contact MEAN WELL for other uses.

Applications

Applications LED street, high-bay, parking-space and fishing-lamp lighting.

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. 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 to PE according to this Class I model’s wiring diagram.
Programmable timer installation This D2 version provides smart-timer dimming and a programmable function. Its purple and pink control wires are PROG+ and PROG−, respectively. Confirm the required programming equipment, procedure and ordered profile with MEAN WELL; D2 does not mean DALI-2 or the analog DIM interface.

Confirm the exact LED load, operating temperature, control interface and installation requirements against the linked datasheet and manual before commissioning.
