| Case and ambient limits |
Operating case temperature: −40 to +80°C, with maximum Tcase +80°C. Horizontal installation: 100% load from −40 to +60°C ambient, then derate to 60% at +70°C. The case-temperature load curve shows 100% from −40 to +80°C. Meet both case and ambient limits; free-air convection cooling. |
| Input and altitude derating |
The 60 Hz static-input graph shows 100% load from 180 to 528 VAC, while its caption says low-input derating is needed. Obtain MEAN WELL confirmation for low-input operation; the graph does not provide a separate numerical breakpoint. 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 65 kHz; PWM switching frequency 75 kHz. PF curves use Tc 70°C; THD and efficiency examples use the 700 mA model at Tc 70°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 75°C or lower. The lifetime graph indicates approximately 100,000 h at Tc 20–65°C, 70,000 h at 70°C, 50,000 h at 75°C and 35,000 h at 80°C. MTBF: 2164.4K hours minimum, Telcordia SR-332 (Bellcore); 202.8K hours minimum, MIL-HDBK-217F at 25°C. |
| Warranty |
Five-year manufacturer warranty, subject to its warranty statement and the specified operating conditions. |
